Hey guys I come from the mtb free ride kinda world. I recently wanted to get involved in 20" bmx racing. So I bought myself a dk fury, and its an ok little bike. But eventualy I want to upgrade, and most of the cranksets I have come over for the bmx market are wildly expensive. So i was wondering If anyone could tell me if mtb cranks will fit into bmx frames. I know they wont work with my fury (im not that big of a noob i know its a american bb) but Im talking for when i do finaly upgrade and get a race frame with a euro bb.
