Milestone

This weekend saw a milestone in build #0, that being the first time the main triangle had been fitted together.  Since the dimensions I knew were that the top and seat tubes were 585mm center to center, these were the ones I laid out first on my plywood template.  Once these were cut to length and fitted, the fixed angle of the bottom bracket between the seat tube and down tube revealed the length to cut the down tube at the head tube junction.

Main triangle tubes fitted together for the first time.

Each lug required grinding down the inside surface where it mates with the appropriate tube.  Early on, my reluctance to remove too much material led me to follow a procedure that was like, grind, test, grind, test, grind, test, before finally arriving at a good fit.  By the last lug, this was more grind, grind, grind, test, grind, ok.  It feels good to be learning and getting the hang of it.

I cut each of the copes using a tube angle jig that worked with a 1/2" drill motor and a hole saw arbor that a buddy loaned me.  I cut the correct end of each tube, indicated by a bit of paint at the end to cut, as the thicker butted section is longer at one end than the other.  This is especially important on the seat tube, as it's only butted at the bottom bracket end and requires no cutting to fit into the seat lug.

Once the tubes were able to be fit through the lugs, I marked each tube's cutline with a Sharpie and scribe by laying the tubes on the template and setting each tube on its centerline.  These marks can be seen on the sides of the tube in the picture below.  I also scratched a small file mark at the point of each lug so that the tubes could be placed into the cutting jig horizontally, as once one end is coped, the tube's orientation is established.

Finally, once each tube was cut, I fit it into the lug and ground the end flush with the lug.  The remaining tasks to complete prior to brazing the front triangle together are to cut the head tube to length and figure out how I'm going to hold it together and in alignment whilst brazing.

Bikegasm

I've always wanted to build myself a custom lugged steel bike frame.  A current gap in my employment as an IT professional, combined with just enough cash to get some parts, and some awesome encouragement from my Velomihottie (thanks, babe!) recently had me going from just thinking about this, to ordering a Columbus SL Tubeset with lugs and all the rest.

Uncut tubeset and lugs roughly laid out on my template board.

Upon receipt of the package, I set out the tubes and lugs to see if the angles and sizes were roughly correct.

Once this was confirmed, I decided to start with the top tube/head tube junction, filing the lug and removing the burrs from the edges to fit it to the top tube.

The idea is to build a classic steel road frame with lively 74 degree angles like the steel racers I rode as a kid.  I plan on it being a size 58.5 center to center because this is the only way to get that size, and that's my size according to Greg LeMond's formula of taking one's inseam and multiplying it by 0.65. It'll have enough clearance for fenders, and I'm still deciding whether it should have rack mounts as well.  I want it to be versatile, but at the same time, I'm a bit leery of cluttering the frame too much with braze ons.

Thought Replacement

Cycling often functions for me as a microcosm of life.  It's a smaller, rather more controlled circle of limited boundaries in which to try things out.  Since much of the focus is on the physical aspect of power against the forces of wind and climbing, it's sometimes easy to forget that it is the mind which ultimately powers every endeavour.

I've been experimenting with saying one word from a mantra or validation phrase on every third stroke of the pedals and synchronizing this with the breathing.  That is, on the first right stroke, I will breathe out, focus on pushing the pedal hard, and saying in my mind the first word of the affirmation.  Then I will soft pedal the next left and right strokes, giving both legs a brief respite.  Finally, I'll breathe out, push hard, and say the second word of the affirmation on the next left.  And so on.

The natural tendency is to synchronize the breathing with one or the other leg, but this leaves things unbalanced.  Focusing on every third revolution balances the effort between legs and repeating whatever affirmation during moments of hard effort replaces any thoughts of the suffering with what I choose to put in my head.  It can be as simple as "keep going."

Risk

Today is two years to the day since Wouter Weylandt died racing his bike in the Giro.

We all take risks every day, in cycling and in life, and often it is the seemingly innocuous little things we don't see that can have tragic consequences.  In Wout's case it was some low stonework that he clipped on a descent, and instantly he would never see his wife and child, nor race a bike again.  And yet, the man died doing what he loved.

RIP.

Souplesse Workout

I did this simple workout the other night to emphasize the Souplesse of my pedaling action.  Yes, it's Springtime in Seattle, and it's generally more attractive during the dark months of Winter than now, but I had been puttering around the shop working on and cleaning bikes.  After taking the Bridgestone out for a few mile test spin, I came back to the shop and rode the rollers.

Rollers are excellent for increasing cadence and fluidity in the pedaling stroke because the primary resistance to keeping the wheels moving is the friction between tire and roller, and there is very little mass to store the energy of the pedaling.  This combination results in immediate feedback to the rider in the form of a smooth whirring sound if the stroke is smooth, or alternately a kind of whoompa-whoompa-whoompa if power is being applied only during the downstroke.  I always begin roller sessions with the awareness of the sound and concentrate on pedaling faster while keeping the whirring going.

Once I'm good and warmed up from this, I clip in only one foot at a time and do sets of rotations with only one leg at a time.  In addition to training the muscles in each leg to fire in the order necessary to rotate the cranks around the spindle, single leg reps will tend to provide information on relative leg strength in the different muscles.  Begin in a relatively easy gear and start by rotating the cranks until exhaustion, noting the number of cycles for each leg and the muscle group that tires first.

Next, go back to pedaling at high cadence while concentrating on keeping the whir going.  I find that this feels so easy with both legs compared with the difficulty encountered doing only one leg at a time.  This indicates that the training is working, and the key here is to focus on continuing to recruit the same muscles in the same order, while maintaining an quick and fluid pedaling motion.  I like to repeat alternating between the single leg muscle recruitment order training and the bi-pedal fluidity focused training until I can only pedal about 25% of the original reps till exhaustion per cycle.

If there are side to side discrepancies between cycles before exhaustion between legs, I might do 5-10 more reps on the weaker side during the alternations.  I also like to incorporate some yoga like poses or sequences to address the muscle groups that were the first to tire.

Happy circle making!

Discovery Park Hill Climb

This is a fun and short, but quite steep climb.  Having just descended this same route from the top of Discovery park, and turned around at the bottom while admiring the oft windswept shore to the west, we turn around and begin the climb to the flatter rolling area above the bluffs.

The climb starts out at a fairly reasonable gradient, but steepens just around the corner to the left.  The grade maxes out at 25.3%, according to the Strava segment for this climb, and it sure does feel steep for about half a km.  Indeed, it is a struggle to remain seated and spin up in even my lowest gears, and the proportion of the climb I can manage this is a generally good indicator of fitness.  But once it's been crested, there is some flat to be had before the road again stairsteps up and around to the descent down the other side of Magnolia.

This is only the beginning.

This climb frequently makes it into my coastal hill rides that are right around my area and more or less within Seattle city limits.

Bike Sharing Coming to Seattle

Puget Sound Bike Share has announced that Seattle will be joining other large cities in North America in and has selected Alta Bicycle Share as the implementation vendor.  Seattle joins a growing list of world cities embracing Bicycle Sharing systems.
