I have two road bikes. One is a cheap-o fixie that I use to pull the kid's trailer and do town runs. The other's I use as a 25 mile round trip workhorse through a hilly and stop-filled commute. In the fall, it doubles as a CX racer.
The spine of this build is a few years old. The FlyXII FR-602 (superseded by the FR-603
, which I believe is identical but has a redesigned fork less prone to cracking). Very cheap now. Wasn't too much when I bought it either - around $550 USD shipped?
I was using this frame with a SRAM 10 speed drivetrain and TRP spyre brakes. Since the main use of the bike to commute I stop a lot. Also, my route is hilly. Plus it rains. So disc. But I was not super happy with the brake system. Lever feel only felt fine within a few months of running new housing and cables. I felt like I had to tweak the brake pad adjust every week. The sensible thing to do would be to try the TRP HY/RD or the Juin Tech X1, but I'm not sensible. Plus I was getting really upset I could NOT get the front derailleur to reliably shift the front ring. It felt like I could only get it set up to almost
shift or drop the chain.
I wanted two things: hydraulic disc and reliable shifting. There also was the complication that my wheelset wasn't 11 speed compatible. I ended up with a 9170 Di2 shifter - XT M8050 rear derailleur - RS785 caliper - 1x11 system. I went Shimano since I read that their hydraulic brakes performed better than SRAM and went Di2 partially because the it is the only way to get non-humongous shifters. I wanted the 8070 shifters, but they still aren't available. Since I didn't want the new build the miss this CX season I did the stupid thing and bought the 9170 shifters.
The goal was to get the bike under 8 kilos and I surprised that I actually did it. Surprised because the bike was lighter than the build sheet said it should be. With a fancier carbon frameset and a $1000+ wheelset this build could approach
7.5 kilos for a CX race.
Future tweaks include SRAM Red hollowgram crank arms, Wolf Tooth chainring, and carbon spacers for the steering tube. Plus a bath.
The bike. After a muddy CX race. Still needs a proper cleaning.
Beautiful 9170 levers.
The awesome new Shimano 11-34 cassette that fits on a 10 speed hub.
Sram Force crank arms with Look Quartz pedals (still works fine even in heavy mud)
China saddle and Ritchey WCS seatpost. Could save another 50 grams with a fancier non set-back seatpost
MT800 'Junction A'
RS785 calipers (post mount frame) and A2Z two piece 160mm rotors
