sorry to bump this one, but a word of advice: i ride my bmx brakeless and can manual 50+ car park spaces but on my trials bike (which is an old school monty stock) i was struggling to get much more than 5 spaces...i realised it was because i wsa always covering my brakes and relying on that to save me from landing on my backside, so i just went death-grip without covering the brakes and it worked a treat! It's easy to hold a manual on a low bb trials bike as long as you can get locked in to it properly and dont grab a big handful of brake everytime you get scared, just balance it withh your body weight!
