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.
Specialized SWorks SL8 light and fast. Sierra Bike Supply was helpful and responsive. Recommended online store.

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.
