>>962974After about 40kph you spin out but at that point it's either too fast and rough to pedal or faster to drop the saddle and aero tuck. You can do ~35kph easy with a 28t up front which is fast enough for most trails. A few pro DH riders are only running 32t up front for extra ground clearance.
>>962975I have a couple grease tattoos from slipping onto big rings, people have been sliced open to the point of needing reconstructive surgery (see the UCI disc brake horseshit). I don't need that shit happening 20+kms from my car in Grizzly country. A big ass chainring on a MTB just gets in the way, not cool when you're riding along rocky exposed cliffs.
>>962976see pic related. I'll stick with my babby chainring and bash guard tyvm.
