Leave your sprockets the way they are and bolt on a turbo no need to worry about any other bike then but if you really wanna change sprockets i ran a 16-42 combo for ages no probs and then went to 17 - 42 and it was still fun your choice mate but be warned the front one is a bitch to get off if you havent got the right tools
