About Groupsets & Build-kits
A groupset is a matched set of components from a single manufacturer that are designed to work well together. If you are upgrading your existing bike or specifying a new one, you can usually save money by buying a groupset rather than the individual parts. Pay close attention to whether all the parts will fit your frame - particularly the front derailleur. Most groupsets don't include hubs or pedals but there are many different configurations so read the component list carefully.
