I’m running hope tech m4’s on 183/183 floating rotors on my bike at the moment. Annoyingly, I’m overheating the front fairly badly on longer descents, and I’m 15st plus gear so not a light lump! I’m debating how to stop the front overheating. The back is just about holding on for now. My options seem to be (whilst staying in the hope camp):
Put a 203 rotor on the front, but unsure there will really be any difference
Put a v2 with a 203 rotor on the front (I believe this will be enough, but not totally sure)
Go the whole hog and put a v2 with vented rotor on the front
Any opinions on which route would be the best in terms of cost and performance? Weight isn’t really an issue as the bike is pretty lightens a bit extra is no problem.
