. In theory, the lower thermal conductivity of carbon fiber can cause heat to build up in the rim during a descent and enough heat will cause a latex tube to fail. I think you and I may have touched on this the other night while discussing the location of brake tracks relative to rim beds: the location is chosen so that the rim bed can serve as thermal mass.Right and in regard to the other thread that was started regarding tires. Enve doesn't even advise latex tubes. I used latex tubes with Enve no problem but it does give me some pause.
That's a deal-breaker right there...I had forgotten about that.
I wonder if that has anything to do with their decision to use hookless beads? I can imagine a latex tube could possibly "jack" the bead right off...
Damn...all this strange stuff people will put up with just because they can't accept that perhaps making a bicycle rim ONLY out of carbon fiber composite might not be the best overall solution for performance :-/
Did not even consider the hookless beads. Do any other manufacturers do that?
IIRC, mostly MTB rims (for example, I believe Stan's rims are hookless), but those are typically all run tubeless AND at much lower pressures.
