I have finished building up my second R5ca, I now have compact rings on my first one. I took a picture with my RZR wheels because they are lighter and I thought it would be fun to post a lighter bike.
Cervelo 51cm R5ca
Campy 2011 Levers, FR, RD, Chain
Zipp VumaQuad crank with Fibre lyte rings
Speedplay X pedals with Ward Ti spindles
Ax Lightness AX3000 brakes with BTP - Bike Tuning Parts Cable Fixing Bolt
Ax Lightness Daedalus Seatpost L1
Ax Lightness Zeus Stem
Ax Lightness AX4100 Compact handlebar
Ax Lightness cages
I-Link cable housings/liner with Power Cordz
Campy 11-25 cassette
Fizik Antares 00
Tune Carbon Top Cap
Arundel Cork handlebar wrap
Tune U20 Skewers
Conti 4000 tires
On this build I tried the Fibre-lyte chainrings and Power Cordz inside i-link housings. I will need more time on the chainrings, the Power cordz seem to shift better than the steel cables.
I never installed the Cane Creek AER headset with norglide, I went with a FSA Orbit IS-CF Headset for the upper headset. I went with the Tune carbon top cap, it helps keep the headset from getting loose.
I will probably have the RZR wheels on my bike that has the compact rings. The Obermayers will most likely be on this one.
I have a couple thousand mile on the Ax Lightness water bottle cages and so far have not lost a water bottle. I like the easy entry as well.
I included a picture of how I set up the brakes with Power Cordz. This was my best guess at the most secure way to install them.
I have a Recon 11-27 cassette that I will try now that I am using the Power Cordz, I did not care for the shifting when using the I-Link steel cables. If that works that will take some weight off.
I have a THM M3 crank on order, that may lower the weight a little more.
I have tried some all carbon saddles, it would save weight but I don't think they are for me.
