Pablo,
How long is the standard warranty on the shifter kit? What is the durability of the crank freewheel? and how hard is it to remove from the crank? Yesterday when i was coming home from a 15 mile trip, the crank freewheel locked up. IT was kinda startling as it threw my feet off the pedals. But now i can pedal in the easiest gear but if i need to use any torque it slips and if i do get the engine running i have to keep my legs spread...fun :/ Would it breaking have something to do with the supplied sprockets being slightle off center?
