Wondering if anyone is looking for one of those out front mounts. Since I changed to the farsports I'm not needing it anymore.

Strange..there was a test in October Tour magazine and fork side stiffness was not outstanding but still received 1.3 note, better than Trek Madone SL6 disc.

I haven't found on this thread for the rim brake build.
Nobody interested in building a weightweenies 2020 rim brake s6 evo eh ?
Despite the non-hi mod carbon, i still think it could be lighter than disc

Is anyone else suffering from brake rub under out of saddle accelerations? Having checked alignment of the rotor it does seem to be coming from flex. Is changing the thru axles for stiffer ones a solution at all?
No flex whatsoever here and I'm no lightweight.

Yes, I get an occasional bit of brake rubbing in the front. I've got SRAM Force AXS and have come to learn that the SRAM calipers hold the pads a little closer to the rotors than the Shimano calipers. It's not frequent and goes away quickly after a couple of applications of the brakes again. Maybe I just need to bleed the brakes.

Disc are here to stay

I think it looks cleaner with integrated hosings on the disc version compared to rim brake version. I choosed the SuperSIX Evo over Synapse because of just integration (and aero)

I'm on Dura-Ace so would've thought tolerance wouldn't be an issue for me, I've put 1000kms on them so was hoping it would've gone away by now...

might want to have your mounts machined with the Park tool or other. I don't think a lot of these frames are really being properly prepared, and disc brakes put a serious premium on correct mounting surface prep.

Finally someone put a small person bike. Want to see more 48s here.
Nice!
What's your saddle height? Looks like a 90mm stem from afar but I'm not quite sure. Did you have a chance to weigh just the frame/fork?

Saddle height from center bb to saddle is 66cm.
The stem length is 100mm
I haven’t got a chance to weigh the frame n fork,but I can feel the weight of the front is way more heavier than my previous bike (Trek Emonda SL6)...I guess the fork is stiffer due to disc brake....

This looks wayy nicer than I expected. Red color SS Evo size 48 is definitely on my interested list for sure.
However, based on stack reach and HTA calculation. To keep 5mm spacer under the stem, I need -17 degree stem 120mm long. Not sure if it'll look too disporposion to the top tube slope of the bike.
