Colony Blaster Chris James BMX Shifters (Polished|25T)

Colony Blaster Chris James is a powerful BMX converter for freestyle bikes. Available in 25T and 28T versions. If you want to achieve higher top speeds, choose a larger chainring with more teeth. However, if you want easier pedaling and better acceleration, then you should choose a smaller chainring. The number of teeth affects the weight of the derailleur - fewer teeth means a lighter derailleur and vice versa. So if you're looking for light weight, choose a derailleur with fewer teeth. This Colony derailleur is designed with a 24mm center hole and includes 19mm and 22mm axle adapters for easy and near-universal fitment.
