while all bikes can ride most things if really pushed to it, DH bikes are good for NOTHING other than DH.
shocking, perhaps not.
but a DH bike, and "a bike for dicking about on DH tracks and mini DH races, NOT proper DH" is quite different.
if you want to get from the top to the bottom as fast as possible, and nothing else, on no other trail than a DH bike, a DH bike is what you need.
be prepared for a bill at the end of every run if your properly giving it death, and probably 20-30 mins of actuall riding a day.
and having to pay mucho denarii to race.
or enter MINI DH and dont worry about winning so much, and just enjoy it.
in which case, a single speed 160mm dicking about bike 😀
