youcould just make some mount converters up...ive got a 26" to 24" vee converter that works pretty well.....the only bad thing is the bb height...e.g a zoot is +35, which equates to a plus +10 stock.......i was thinking about converting my woodstock originally which is zero.....when used with 24" wheels would make it feel somewhere in the minus bb range...not too great for trials

Don't think there many real options other than the frame having a standard disc mount. DMR bikes do removeable vee brake mounts on their frames but weather or not they will fit on todays trials frames is questionable.....doubtful. Not many fork options either.

Correct me if I'm wrong but I dont see how the bb height would change if you change wheel size. BB height is axle to BB rather than floor to BB, and as the axles are in the same place regardless of the size of the wheels the BB height wont change.

Could try finding a caliper brake to v brake adapter plate (like this), then see if you can position it so the bosses are in the right place, and there is enough plate covering the maggie mounts to allow you to drill holes into the plate and bolt it to the maggie mounts. Not sure if the adapter would have long enough arms though, or where the hell you could buy one from.

Yeah but you have to take into account that a 26" has a 25mm higher BB than a 24" with identical geo.

surly thats from the floor though, and so makes no difference to the bb height relative to the axle, which is what is quoted as bb height (as I understand it)?

I was confused by that too when i was gonna convert my 660 - put the 24s on it and it feels loads different! Just feels an awful lot lower. Great for bunnyhops, spins etc but was a bit of a dog on the back wheel with the neutral bb height. Was great fun though!

maybe this kind of booster from some RST fork could be used for converting brake mounts:

back side of the booster:

I guess in this case distance between those mounts doesn't fit ):

sorry for my english :b
