Mongoose 26" Mens XR-75 Mountain Bike Questions & Answers
There are no threads on the crank arm to screw a pedal on. What do you do now?
1. replace the crank.
2. Purchase a Heli-Coil or other brand at an auto store. It looks like a tube with threads on both sides that will screw in to the stripped hole and there by install new threads. Bring the pedal to the auto store to make sure it will thread in to the "female" threads on the Heli-coil.
The problem is the pedal is steel and the crank arm is soft aluminum. Also, people damage them because one pedal is normal thread and the other is reverse thread meaning you turn clockwise to loosen.

Understanding Sag
In order to let the suspension work properly, we allow some of the rear-wheel travel to be used when supporting the rider's weight, this is called 'sag'. The basic idea is to have around 10-20% of your bike's total travel as sag. This allows the rear wheel to drop into dips in the trail and maintain contact and traction.
Adjusting Sag on Rear Suspension
Changing the amount of sag in the rear suspension is done by increasing or decreasing the spring rate of the rear shock. The rear shock's body is threaded and you will notice there is a nut on one end of the spring. Turning the nut in the direction that compresses the spring will increase the spring rate and reduce the amount of sag. Turning the nut in the direction that expands the spring will decrease the spring rate and increase the amount of sag. Never turn the nut to the point where there is space between it and the spring, this may cause damage to the shock.
