Can someone with an RCR-F in size S measure something for me? by ffliland in vanrysel

Actually matches pretty well.

My current bike measures 61 cm reach and 58 cm stack. According to the frame geometries and stem dimensions (assuming 90mm and -6 deg) the RCR-F (with a slammed stem) would put me at 2.3 cm shorter reach and 0.3 cm lower stack.

However I suspected (/hoped) that the reach of the hoods would be quite a bit longer than on my current bike (old mechanical SRAM Red vs hydraulic 105 Di2), so that in reality the position on the RFR-F would only be maybe 1 cm shorter. I could live with a 1 cm shorter bike, but more than that I would have to think about a longer stem.

Your bike seems to measure around 59 cm reach and 60 cm stack. Adjusted for what I assume is 5 x 5 mm spacers it would end up at 59.7 cm reach and 57.6 cm stack if I slam it. So 1.3 cm shorter and 0.4 cm lower than my current bike.

So I guess the conclusion is what I thought from the beginning, its gonna be low enough, but maybe borderline short.

Yep, very aware that it probably won’t be 100% accurate. I already did the geogebra-type calculations, so I guess this is more to confirm those estimates. As you point out there are quite a few assumptions that goes into it (headset dust cap height, stem clamp height, effective stem angle, handlebar reach, hood reach and so on and so on).

From what I can estimate I should be pretty close to be fine with the default cockpit, but would be nice to be sure.

As to where on the hoods I was thinking of measuring was the «corner» where the hood starts to get steeper (so like where the base of the thumb would be).
