Update: June 2013
Got a little busy last year job hunting, and moving, so I never really wrapped up the progress on this bike. In terms of BOM (bill or materials), the following have been added:
- Shimano XTR Cassette (11-34t)
- Shimano XT Crankset (44-32-22t)
- KMC X9SL Chain
- SRAM X7 Long Cage Rear Derailleur (MTB)
- SRAM X7 Shifters (MTB)
- Thomson Elite Seatpost
- Brooks B17 Special Saddle
- Profile Design AquaRack (holds 2 bottles behind seat-post)
- Planet Bike 1 watt LED tail-light (I have these on all 3 bikes)
- Yokozuna brake and deraileur cables
- Michelin CIty 700 x 40 tires (usually)
- Some thingy to hold my phone
I bid on Brooks Swallow seats, with Ti rails for months, and finally got one for $180. I applied Obenauf's Leather Protector, and rode a few hundred miles, but never achieved the comfort of my Brooks B17s on the other bikes. It really looked beautiful - right for the bike, but I ended up getting another B17 - this one a green special (with copper rivets). It was more comfortable "out of the box", and now with a few hundred miles on it, the sitbones take at least 4 hours to feel sore.
I ride mainly on gravel trail, and on some rough roads, so I put big ol' Michelin City 700 x 40C tires on the bike - usually kept at 40-50 psi. I figure'd I'd ease into speed, and hang on to some comfort. It always feels so much faster than my mountain bike or my utility/commuter bike, that I haven't thought much about it. With a century coming up, I finally ordered some fast (low rolling resistance) road tires - Schwalbe Ultremo ZX 700 x 28C.
On some training rides for an upcoming century, I decided I'd try aerobars. Primarily for another riding position, and secondarily for an aero position for the time I spend riding alone. I've done 75 miles with them, making adjustments and feeling them out. I had to find a wide and raised position for the arm-rests so my knees clear my gut. For hard "sprints" the position feels good, but for "spinning along" in an alternate position, I bounce a bit more. I've done most of my riding, and learning a good "spin" in an upright position - I'm not as smooth leaned over.
With the aerobars, I've raised the seat 1/4", and tilted the nose down (from a somewhat tilted up position) about 1/4". I think it will move forward a little as well before I'm done.
In terms of speed/efficiency - each time I drop onto the aerobars, I shift up 1 gear to keep the effort about the same. Looking at gear ratios, that's around a 10% reduction in effort - which could prove pretty significant, even if I'm only "alone" and able to use the aerobars 10% of my time in the century.
I love the bike. It's comfortable, fast, quiet, smooth, and wierd - but perfect for me.
