Hi i have a koxx xtp 20 and today i went to fit my chain to it i have a kmc chain. one big problem is that i have to have the wheel as far foward as pos so the brake can be set up to the rim but then the chain is too loose, But if i tension the chain its night and tensioned but thwen too far from the brake, but when i take a link out of the chain it wont eithen fit on the bike. Any suggestions for me ? split link ? if so where from.
