There are a few skateparks around that won't allow disc brakes - there's a couple up in Scotland and I think a few more dotted around in England too. Reasons range from "If you break a hose we'll get oil everywhere" to "Disc rotors are dangerous" - i.e. bullshit
Hi Archie, yep there’s nothing against disc brakes in the park, a couple of the guys who ride here run double disc as it is. Out of curiosity why did you think there might not have been an allowance? Just wondering!
