Picked up the 41. and after a bit of adjustments had this girl running like a champ. Took it for a ride around the neighborhood like 8 laps atleast, no problems. Haven't been this stoked since I lost my virg... oh safe for work. Came to a stop to let her cool down and check everything. Some cute college girls approached me asking about it and took pictures. Later went to the store and ol' timers where gawking at my creation. Still plan to replace this junk tensioner asap. But for now I'm just enjoying the ride!
