without getting into the pros and cons of disk brake road bikes, has anyone managed to build up a sub 6.5 kg bike? what about a truly weight weenie build?

The Focus Izalco Max Disc with Red comes in at 6.83 kg. The dt rc 38 wheels are over 1400g so without much fuss I think that'd easily be sub 6.5kg.

I'm building a SS EVO HiMOd Disc with Etap HRD, frame should be here in a few weeks but everything else is ready go. Might do a build thread for this one as there aren't many for disc bikes yet.

Haven't weighed everything but based on a mix of actual and claimed weights it should end up around 6.3kg. Only truly exotic WW part on the bike will be the Berk saddle.

@jlok. Wheelset is Bontrager Aeolus 3 TLR D3 clincher. Still need to weigh them but should be around 1450g for the pair.

I'm hoping for 6.3kg but would be happy with 6.5kg which would still be 1.3kg lighter than my CAAD10 Black Inc Disc.

use this di2 combo: ST-R8070-L+ST-R8050-R or ST-R9170-L+ST-R9150-R - this sti have same shape
get front disc wheel (20h lacing 2x/1x no brake track) and rear rim brake wheel
saves a lot of rotating weight on rear spokes
you get extra stopping power and extra modulation where you really need (front)
you can save rear wheel brake track most of time (when it's safe to use front disc as primary brake)
saves your time on rear wheel operations, no need to re-align rear rotor

this will not work with mechanical shift, because mechanical sti for disc and rim sti have different shape

I'm interested in seeing this.

Which wheels will you be using? I'm looking for some wheel inspiration.

My bike has DT Swiss R23, about 1700g, bike is currently 7.3kg(inc pedals & Garmin) so absolutely no WW. I'd like to get it to about 6.8kg - just because.

How are the Biturbo wheels compared to standard spoked carbon wheels?
In anyway harsh riding?
