With the Park Tool CC-2 Chain Checker you can quickly and accurately determine the wear (or "stretch") of nearly any bike chain. Simply insert the Chain Checker’s pins into two links, lightly press the swing arm gauge, and then check the gauge window for an accurate reading. The CC-2 is compatible with most single-speed and derailleur chains, including Shimano XTR 12-speed chains.
5-to-10 speed chains: replace chain at or just before 0.75%
11-to-12 speed chains*: replace at or just before 0.5%
Single-speed chains: replace at or just before 1%
Check with manufacturer for specific replacement instructions

Great way to charge both the bike and range extender/extra battery at the same time reducing charging time and charging each one by one. Very convenient and useful.

Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.
