Can’t See the Forest for the Trees

It’s been pointed out to me twice in the last 24 hours that this place has become too silent.  I’ve been struggling with blogger’s block of late if I’m honest.  Still out there riding, sweating and swearing but when I sit down here, the day evaporates and I find myself reading the things I said I wouldn’t and not writing anything.

I’ve managed to avoid the “this piece of laser-guided, alien-inspired carbon-billet doo-daddery that weighs precisely 3 french fries less than your current one is a must-have at only $1500″ pseudo magazine articles however in my on-going dithering about a new bicycle, I’ve been scouring the internet endlessly.

The Stevens Carbon Team in all it’s Germanic perfection…without disc brakes sadly.

After 10 days of waiting, the you need to show more interest than going down there 3 times to tell them you’re interested before they’ll respond to you bike shop finally responded to my subsequent interest-expressing email with a very reasonable quote on a Stevens Carbon Team frame build.  It was good enough to pique my interest despite the lack of one of my key want features – disc brakes – but their so-low-pressure-sales-we-won’t-do-anything schtick eventually wore me down and I moved on.    Just as well, I want those disc brakes.  In my three previous interest-expressing trips, I’d expressed my desire for a Stevens Vapor – the only one with discs – but was eventually told via Guru Thomas that they wouldn’t order it because they didn’t want to get stuck with it.  I’m not going beg you to take my money…

Now disc brakes on bikes are the subject of all sorts of internet and bike-shop debate from the barely reasonable – they add weight to the utterly ridiculous – they’re too powerful and lots of inexperienced riders will crash after they lock up their front wheel while blazing down the mountain pass in the rain.  Yeesh.

In fairness, they are heavier – about 300 grams to go from cantilever to disc.  Less than a 2nd water bottle.  I’m not in the pro or amatuer or any peloton nor do I see the 300 grams of extra brake as a deal-braker when I’ve got an easy 3000 10,000 grams around my middle I could shed.  The latter argument – too much power – doesn’t warrant an actual rebuttal it’s so utterly cockamamy.

I would like to comment on another reason I’ve been given to avoid disc brakes – they’re not hydraulic.   Disc brakes come in two fashions – mechanical/cable operation or hydraulic operation.  If I was given the choice, I’d certainly pick hydraulic over cable.  At the moment there is precisely one manufacturer making a hydraulic brake system for road/’cross bikes (yet numerous for mountain, this due to the UCI – the cycling version of the FIA, only just approving discs for cyclocross bikes) and they’ve not released anything to the public yet, rather continuing to work with Colnago on their beautiful C59 road bike.  I’m not sure which would cost more however – the C59 or the divorce that would inevitably result subsequent to it’s purchase.

Mechanical/cable versions are very simple – pulling the brake lever pulls a cable.  The other end of the cable is attached to a lever that is attached, for the purposes of illustration, to a threaded ram.  Pulling on the cable pulls the lever which causes the ram to rotate, which causes it to move in towards the disc by virtue of the thread.   A brake pad is mounted to the end of the ram and thus when the ram is rotated inwards, it pushes the pad into contact with the disc.  Bicycle brake discs are thin (1.5mm or ~0.060″) and somewhat flexible so as the pad is pushed into it from one side, it flexes away from the pad and makes simultaneous contact with a pad on the opposite side, ultimately sandwiched between the two pads.  A spring on the ram rotates the pad/ram/lever assembly back out when the lever is released and the disc, now unstressed by the pad, returns to it’s previous position, no longer contacting the inside pad.

Absolutely simple and quite effective – certainly more effective, and more importantly impervious to the elements than any rim brakes currently available.  Granted, it’s subject to cable-related issues – stiction, cable stretch and jacket collapse among others.  These issues have existed since motorcycles were introduced as they’ve used, for a century or so, cables for operation of the clutch, throttle and even early drum brakes.  Mechanical brakes also require consistent maintenance as there is no automated means to compensate for pad and disc wear.  This takes all of 5 minutes every Sunday evening as I prep the Rescue Bike for another week of riding.  If I get around to it (the maintenance that is).

Hydraulic brakes function like scaled-down versions of motorcycle brakes.  Powerful, linear, exceptional and capable of both tremendous stopping power and remarkable modulation.  Using the principle of Pascal’s law, they use fluid under pressure in place of a cable and a piston (or pistons) in place of the ram.  The spring is replaced by a deformable D-ring seal – the D shape of the seal allows the piston to slide out while deforming slightly as the piston, under pressure from the fluid, pushes towards the disc.  That seal deformation in combination with subtle piston-chamber design pulls the piston away from the pad (and thus disc) when the brake lever is released.  Hydraulic discs are more refined than mechanical to be sure – you don’t have to adjust them for wear – the action of the D-rings seals and piston motion serve to automatically adjust position every time they’re used though a dirty or poorly maintained setup will drag the pads on the disc.  They’re powerful, far more so than mechanical and infinitely more than rim brakes.  Their single drawback (in my eyes – I don’t care much about weight or being too powerful after all) is the brake fluid.  When it’s clean and bled properly, there’s no issue but air in the system can be a nightmare to get out.  This isn’t a use issue of course, just maintenance related.  Take care of them and they’ll take care of you.

So if a rider wants to step into a road or cyclocross bike, wants disc brakes and wasn’t born into a family of investment bankers, the choice today remains mechanical/cable.  Amusingly, those that would advise me to fore-go the mechanical discs because they’re only cable, not hydraulic somehow miss entirely that the rim brakes they’re admonishing us to stick with are – yup – cable operated.

In the event you’re confused by the cyclocross reference, see here.  An insanity originating in Belgium it involves pavement, mud, grass, snow perhaps, steep climbs,cow bells and barriers that require you to carry your bike.  The course is unrideable by design – but it’s spawned the ultimate do-everything bike.

 

Never say Never

The problem with saying never is you’ve immediately made a commitment.  Some, like saying I’ll never smash my fingers with a hammer for entertainment are pretty easy to keep admittedly, but saying something as foolish as I’m never riding in the rain…again…until I get rain gear are arbitrarily limiting, and who likes arbitrary limits?

I started off last year avoiding the bike if it even looked like it might rain.  This wasn’t so much a fear of rain as an excuse to take the day off.  The introduction of our Gentlemen’s Wager (first to 1000km) rewarded riding in the rain, doubly so when my competition wouldn’t.  While I wouldn’t say I embrace riding in the rain, I wasn’t letting it stop me.

Tuesday afternoon, I rode home in a rain that had me sloshing about within the first two kilometers.  It was a miserable ride with miserable rain and a miserable headwind.  I did not enjoy the ride as one might infer and I vowed no more riding in the rain until I was properly outfitted.  That arbitrarily limiting statement stood three days before it became a challenge.  A challenge to which I quickly succumbed.

Ordinarily one might think of failing a challenge to be failure.  In this scenario I think failing to live up to the statement I’m not riding in the rain is in fact the preferred course of action.  I am, after all, not made of a water-soluble exterior (at least not while I’m still moving and breathing), and the gear that I have keeps me reasonably warm.  Or so I thought.

It started innocently enough.  A check of the forecast this morning showed a light rain turning to snow as the day wore on.  The radar map showed a large green (IE rain) mass heading from the west but the timing showed the worst of it arriving about the time I was due back.  I questioned my wisdom as I geared up, stuffing my pockets with enough road fuel for a 3-hour trip, strapping on my sort-of water proof Gore-Tex pants and my not-water-proof riding jacket but forged ahead with my ride.

The relative lack of puddles and the dry spots around parked vehicles suggested a lack of significant precipitation.  The wavering trees confirmed the presence of the 33km/h NW wind.  Did I forget to mention that bit?  Oh – yes, in addition to the precipitation, there was a wee wind.

The geographical location of home base presents some logistical issues when faced with a north westerly wind.  We are higher than the primary north/south pathway system, which lies to the east.  We go down to the path and up to home.  Heading south on the path is, with a handful of exceptions fairly flat – easy pedaling – and as such, my desired direction.  However, while it would be a fast and easy trip south, it would mean the entire return journey faced into the aforementioned wind.  Not appealing.

Head west or north from home base and you’re climbing.  It’s not huge elevation nor is it killer-steep.  It’s a long, steady slog up the hills and today, into the wind.  I opted to tackle the hills and the wind first, riding north and west as far as I could before heading home both downhill and with a tailwind.  Excellent plan.

I don’t often ride in the northwest as I have no destination there.  This means I’m not overly familiar with the path system or even the road network.  I can’t keep track of which trail or boulevard is going which way.  While the City of Calgary has done a commendable job signing the bike routes on the roads, there are some gaps and I could not for the life of me figure out how to get over – or if I wanted to – Beddington Trail while staying on the path.  It didn’t help that with the overcast skies and the lack of streets or avenues (so one might be able to figure out what direction he was pedaling), I had no idea what direction the road  was going.  I knew I wanted to go north, but I no longer knew where North was.  I headed down dead-ended bike paths, back-tracked up hills and generally confused myself a great deal.

I could have used my gadget to look at a map, find my position on it and then reference the fantastic City of Calgary Pathway and Bikeways app to figure out how to get where I wanted to go.  I didn’t do that.  I didn’t do that because that’s not what I do, apparently.

The precipitation was no longer a drizzle.  It was a full-on rain but I’d thwarted it with careful seam preparation and thick winters sock over my double-layer winter running socks, a gift from Best Wife.  While I was pretty sure parts of me were getting wet, I was still warm save for my face so I ploughed on trying to find a way over to Nose Creek park from the north side of whatever that road it s that runs east-west (that’d be Beddington Trail for future reference).  I continued to twist and turn until I crossed a pedestrian bridge over a multi-lane road (success!) and began heading east.

The quick blasts downhill stung my face with rain turning to something more solid and there was standing water on the flat sections now.  Slogging along up a long hill, I caught sight of another Porsche parked in someone’s driveway and thought to myself – what a strange coincidence, two convertible Porsches back into their…wait a minute… nooooooooooooooooooo!!!!!!!!!  Ah damn!  I was not going east.  I had not crossed the right road.  I was going in circles.

I pulled under the cover of the Husky gas pumps and ate a Honey Stinger waffle while I pondered my next move.  I had no idea where I was, how I got there or where I should be going.  I’d been riding for an hour and was no longer warm and dry, my feet squishing around in wet socks.  I picked a road at random and followed it until it turned into something I recognized and then followed that.  Slowly I picked my way back to Centre Street and Beddington something-or-other where I knew I’d find my path north.

Slowly I ground up the hill into the driving rain and headwind, knowing that some downhill salvation was waiting on the other side.  I was cold, wet and fully insane in my determination to get where I was going.  I pedaled down the hill to the underpass which would feed me into Nose Creek Park but stopped short.  Do I really want to do this?  I could turn around right now, slog it up this hill and then coast downhill almost all the way home.  Home, where it’s warm and dry and I can climb into a hot shower.

That’s the thing with insanity.  It’s insane.  I pedaled north, fighting with my clipless pedal that was refusing to clip (making it remarkably slippery as wet metal on metal tends to be).  I started talking to my pedal out loud which should have been a sign.  Finally clipped in, I rode into the deserted park and headed east.  The rain left large puddles on the trail and the drivetrain sprayed water up the back of my right leg until it finally found a way past the Gore-Tex, dripping it’s icy self down the back of my formerly dry calf.  I did not smile.

I chose the easy route out of the park, anxious to head for home, having accomplished my crazy, pointless mission.  The north wind was pushing me furiously and I found myself in the top of the big ring, making my first real speed of the day.  I checked my mileage and the time, thought about the consequences of going past my turn and decided to push for the river.  My gloves were soaked through, frozen fingers and frozen toes a constant distraction.  I rode on averaging 30km/h over the next 10km all the while the return trip looming in my mind.

I stopped under the Memorial Drive overpass, common sense finally trumping the enjoyment of speed.  I snarfed down a Clif bar with shockingly numb hands, making a futile attempt to hide from the wind behind a bridge pillar.  I could no longer ignore the pain coming from my wet toes and my fingers were all but non-functional they were so cold.  The rain had long turned to a heavy wet snow making a less-than-stellar ride that much more arduous.  I stuffed the empty wrapper in my jersey pocket and turned around for home.

The ride home was exactly as you might think.  A freezing, driving slush/rain, a fierce headwind and a Rescue Bike that was beginning to malfunction.  I couldn’t determine whether it was my inability to feel my fingers that was hampering the bike, or if it was the bike rebelling against the conditions.  I stared at a spot a few feet in front of the tire, shifted into the middle of the middle ring and tried not to think about my frozen appendages.

Half way up the bus trap hill, I determined that in addition to my own lack of digit-functionality, the Rescue Bike was indeed sick.  I tried to shift into the granny ring so I could sit and pedal slowly up the hill but it wouldn’t shift.  This is most distressing when you have already made the mental leap to a lower gear and it is the first time in memory I debated getting off and pushing rather than risk falling over with my feet frozen to their pedals.

I made it to the top of the hill and, knowing the rest of the climb that was waiting for me, I persuaded the chain onto the granny ring and climbed the last kilometer home.  I managed to get the Rescue Bike up onto it’s perch before making a bee-line for a hot shower.  My fingers howled in protest but my feet made no complaint at all, at first.  Without warning, my toes started signalling that they’d been run over by a truck, smashed with a hammer and stubbed against a table at running speed.  The pain was enormous.  I was paying the price for ignoring them when they signaled their increasing displeasure and finally their resignation during the ride.  Despite growing up and spending my I don’t need a toque just because it’s -30C years in a place that has an average winter temperature of -30 degrees, I don’t believe my toes have ever been that cold – they’ve certainly never shared their anger with such clarity before.  It was an excruciating 5 or 6 minutes before they started to calm down.

It’s now 12 hours since I embarked on my frozen adventure and I’ve recovered nicely.  My muddy clothes have all been washed and hang-drying in anticipation of another outing.  If it wasn’t for scheduling conflicts, I would be gearing up for a 2nd round as we speak.  Clearly I haven’t learned anything.

Do you see what happens when you say never?  It’s makes you crazy.

The Harder I Work, the Luckier I Get

Today was Clark’s funeral and I learned a few things about the man.  The place was standing-room only with vehicles lined up and down the streets for blocks.  It would seem the lasting impression he left with me, he left with many, many people.  A man devoted to family and to achieving excellence at work and at home.  The world was a better place with him in it.

Attending the funeral in the middle of the morning meant some time off work.  This translated to an extra half-hour on the bike in what has to be some of the coldest weather I’ve ridden yet.  The ride started out at 4 degrees and slowly dropped to 2 before climbing back up again by the end of the ride.  I know it’s just the end of April (as I write) and we’re just as likely to see snow as sun but I could use a few days of warm morning riding.

The biggest drawback to the cold temperature is the requirement for gloves to keep my hands from going numb with cold.  Of course thanks to a combination of hand position, seating position, bike size and good old fashioned biology, when I ride with gloves, my hands go to sleep instead – especially my thumbs.  There are two pads on the heel of your hand and the nerves run between them.  Using a padded (read “insulated) glove and positioning myself the way I do means that padding puts pressure on the nerves and the next thing you know I’m shifting gears instead of gripping the bars.  It’s rather annoying and occasionally problematic but it beats the typical cycling gripe (you know, the seat-related one that’s not a problem with your seat).

I managed to put on just shy of 50 kilometers this morning and found all sorts of new ways to torture myself with hills.  Newsflash – the only way I can avoid riding up hill to get home is to start out climbing up hill towards Nose Hill park.  The problem with doing that is it doesn’t get me anywhere near work and rather obviously – I’m still climbing hills.  In fairness to my progress, climbing hills is – I was going to say getting easier, but that’s misleading – getting less death-like.

I wouldn’t go so far as to say something ridiculous like I pulled out all the stops (ridiculous because I didn’t pull out all the stops – I stopped often and am stopped now) or even I gave it everything I have, because I haven’t done that either – I’m still quite spoiled in fact.  I did however learn one very important thing this weekend – if I don’t do it (it being whatever it is I’m doing) first thing in the morning, it probably isn’t going to get done and that (the not getting done bit) will make me short-tempered and agitated and pure pleasure to be around.

As I tried to catch up to Adam and Alberto, I’ve ridden as many miles as I could get away with without putting a strain on things at home.  I’ve been getting out a few minutes earlier in the morning and riding a few minutes longer in the evenings while keeping the home-front semi-stable.  This weekend I managed a 2 solid rides and an outing with the eldest for a bonus 7km (A quick topic-drift here – the eldest was amazing this weekend, pushing his Canadian Tire 40-pound bike up the steep, grass face to the top of Nose Hill because he wanted to ride around up there.  That’s determination.)

All of the effort was rewarded with a jump from 3rd to 1st place this (Monday) morning.  I leapt up to 473km.  Adam, thankfully, took the weekend off, I suspect to put some competition back into the competition, so is sitting at a solid 456km (as of 9:00 am) with Alberto, despite a huge 80+km effort on the weekend, sliding into 3rd, 150km behind 1st.  In fairness to him, he rides exclusively in the evening and I see he’s put up another 47km ride tonight so as long as I don’t ride for two more days (and he continues), he’ll almost be caught up.  Of course Adam will have continued riding so all that means is we’ll both be well behind him.  So – I’m afraid I’m going to have to keep riding.  Chris is having trouble with his electronic gadgets so updates are manual – I have no idea where he’s at now but he was a solid 115km on Friday.  Late entry Johan the Accountant was sitting at 110km and Jon the Safety Dude a solid 0.

By this time next week, this is anybody’s game however there’s a really big problem lurking.  Despite my attempts at having Adam shipped away on business for a few days, it is I who is heading off for 3 days next week.  That’s 3 days without riding.  That could put Alberto 50km in front of me (and Adam 105km if all he does is commute!).  I need a strategy.

I should take this opportunity to say I believe I am crushing all comers on the elevation race.  The First to 10,000 meters that I instituted last week – seems I neglected to directly inform (though I must say it was published publicly, accessible from pretty much anywhere in the world…) the rest.  They think it’s cheating, I think it’s clearly and obviously not.  And I’m winning.  :-D
