Bsa C15 Rear Shock (length)

[dot1dog]

hi i am busy converting a road c15 to trials was wondering if i should fit standered length rear shocks or should they be longer, my concern would be lifting the rear end to high and making it look really stupid

cheers

Use 340 mm ones on mine. Seems fine and this length is widely available. A lot depends on the length of your forks and the steering angle you are trying to aquire.

One other thing to be aware of is if you go too long the chain will try to saw its way through the swing are spindle

thanks for the info,was reading a article on bsa b40 trials about inserting 1" spacer in top frame tube to alter the rake and trail would this be the same for the c15 cheers

Yep know the article you mean. Mod works for the C15 same as B40. However before i started taking an hacksaw and welder to the frame i would fit the longer rear shocks. As i saids before longer shocks lift the back end and increase ground clearence but also steepen the front fork angle. Think of it like a see saw.

You may not need to fit a spacer after fitting the rear shocks

If you go too steep with the rake the bike tends to "tuck under" on tight turns so i would try it first and see how you like it as is.

Personally i prefer not to hack the frame unless i have to.

Good luck

thanks for the advice,still along way to go on the conversion tho as it takes as much money as it does time and her indoors does not have the same priorities as i do when it comes to spending , but i will get there one day.
