HI everybody! I am new to this forum but I remember 20 years ago being part of a forum that probably has disappeared since. I am a mountain biker and have been riding MTb and BMX since the 80's. I have to say trials have always inspired me and impressed me greatly. Only this year have I been able to take the time and motivation to really practice moves like the backwheel hop. I was so proud to hop 4 times within a few hours of practice I now know I could go further into it and learn techniques I never thought I would be able to do . Yes I am 42 and not extremely in shape, but I hold my own and will do MTB races in 2021. I just wanted to introduce myself and let you know that I am going to use a full suspension 29er bike. If you have any advice, please let me know. Is there a way to build a trials bike with my old GT BMX? I think I would just need very, very strong brakes and a new smaller crank but any advise is welcome. Thanks and ride on! J
