Buying Guide for Single Speed Conversion Kit

Without a buying guide, you won’t know what to look for when checking out a kit. So, let’s look at some of the factors that contribute to the performance of your conversion kit.

Durability is of special importance when buying a speed conversion kit. If the components break off when you're on the road, then you'd have to drag the cycle all the way home. Check for the quality of materials - the main body of construction should be strong yet lightweight. Something that Chromoly steel would be perfect.
