Sweet hat that fits nicely under the helmet and is awesome at keeping sweat out of the eyes. It doesn't seem to make me have that feeling of overheating like other skull cap type underhelmets have in the past. I give it thumbs up
This jersey fits well and the material seems to do a good job of keeping climate control. Nice optic wipe built in and a neat audio interface( basically a pocket with a specially placed hole for headphone cords) make it even better. Plus they look cool!!
If your asking about rim brakes specifically, then no. To my knowledge there are no hydro rim brakes. Nothing else compares to hydro discs. Not only because of modulation but also stopping power and performance in adverse conditions such as mud or water.
