Corrected ! Magura make a set. But more importantly, the whole world dosen't revolve around 4 bolt mounts. And to awnser the guy's question, If you are looking for a Trials specific frame i'm sure there is something out there. But if i were you i'd stick to a more streety frame, like a Leeson or a Curtis or a Pashley (if your really cool) Because all of these frames will work reasonably well with Suspension forks and have great Geo. Then once you've got it nailed move onto something trials specific ? Or, just buy a real cheap Stock and wreck it learning the basics. But remember, no buying or selling in NMC ! (Probably your best bet) Hurry up and Validate this guy so we can help him out ? Jarrod
