Cheers guys. Yeah, not keen on going all out for something like the Onza T Pro, looking for 26" (or possibly 24") and some sort of saddle- a sort of mountain bike/street trials crossover, the Hex looks more like what I'm after.....small problem of the £400 frame price tag though!
I was thinking more along the lines of getting a small strong and light mountain bike frame that can get the saddle down low (like the 14" Trek 4500 Azonic DS-1 I have just seen on eBay) then gradually adding trials parts to it with my £40 per month budget. Bad idea? Are there any recommendations for cheap non-trials specific mountain bike frames that would work well for this for a 26" build? ....Im assuming that if I can find something strong, light, relatively small (considering I'm 6'3) and with geometry that can get the saddle out of the way then that would be a reasonable starting point?
