I had a few questions about some parts and stuff that dont really matter but are somewhat intriguing to me.. Why dont trials riders use titanium frames? I know nothing about them but arent they light/stiff and whatnot? How many people actually change gears while riding trials? Unles you ride to the place I havent noticed many people switching gears, so why not single speed on a stock bike? Would a Rohloff speed hub thing be good for trials? Minus weight maybe..? How do you distinguish a UCI from a BUI frame? I havent looked anything up on that, only thing I know is one uses bashguard and the other doesnt..and whats wrong with using a bashguard? How come people dont use the Knifen forks? Ive read alot about flex and all and then Ive read about that being a very stiff fork..why not use it? Thats all I can think of now, thanks for any answers.
