stripped crank + popped tire
ok... so i was riding XC the other day and the left crank was loose but i kept peddling on it (bad idea). After i pedaled on it for about 5 minutes it came off. I found it was stripped a little. I tightened it up, thinking it was good to go, but now it loosens up every 30 minutes. Do i need to buy a new crank set?
Also, I was urban mtb'ing today and jumped a six stair and my back wheel popped. (with a Kona Kikapu [full suspension])
the funny thing is, i jumped the same set of stairs with a $200 full suspension walmart bike and it was fine.
How is it that my kona tire popped but not the walmart bike?
