Hi all, i recently bought this trials bike as abit of a project from what i can tell its a Megamo Frame and crank not sure about the wheels allthough i took it to the locall bike shop today and he tols me he knew the previous owner and the wheels are worth alot alone The front brake is just a normal disc brake and the back one is a magura v-brake. I want to change basicly all the parts for new one eventually and just wanted some hints and tips on what to get and thought you guys will know alot more about me as this is my first project, so all info big or small will be very usefull to me. Thanks in advance! http://www.tartybikes.co.uk/cranksets/onza_zoot_crankset_with_bashring/c11p11433.html Is this crank any good? Allso not sure about what size rims to get or whether to buy them ready made? Ive seen alot of different pro riders with plenty of different size's i like the way they are now and feel comfitable is that all that matters?
