So with that in mind, what are you using, pro’s / con’s etc?
Road - 40cm - switched to these from a 44 for the aero benefit - but about to bump back up to 42. The 40s just feel a little too narrow and my upper back/ shoulders feel tight after riding with them.
Gravel - 44cm, lots more leverage and I find them more comfortable on longer/rougher rides (I also ride some singletrack/doubletrack as well as road/gravel on this bike, so the extra leverage is nice)
TT - 40cm, I don’t have the same issues with these as the 40s on my road bike, probably because I’m not on the bullhorns much.
