Mongoose R1602... | Answered on Aug 20, 2009

Mongoose full-suspension mountain bikes, like the Ledge 3.1, have a little bit of height adjustment for the handle bars. See the manual at https://www.mongoose.com/pages/product-manuals . The current link to the appropriate manual is https://p.widencdn.net/brqquy/OMMGFS-1_Mongoose_FullSuspension_OM . Start at page 18 (20 of the manual in the browser) and determine the type of stem on your version of the bike. The quill stem version has minimum insertion marks that must be below the top of the headset and not visible. For the threadless stem version of the mountain bike, you adjust where the handlebars clamp onto the steerer tube. However, this is very imited since there should be only 1/8" to 3/16" gap between the top of the handlebar stem and the steerer (stem) tube. The is where the top cap and bolt to replaced on the handlebar stem and thread into the steerer tube.

I hope this helps.

If you have no idea what's wrong then you probably would not be able to fix it either. If a brand new bike then contact the seller for help, see if there's a bike co-op in your town, or go to a bike shop for diagnosis.

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.

Google "mongoose serial number". That is what anyone here would have to do to answer your question. You may or may not be able to determine the age from serial number, but bike condition is far more important than age..

"Size of what? chainwheel, crank length, Bottom bracket spindle length? Not possible to say in any case, as manufacturer specs can change, even in a model year. Take to a bike co-op or bike shop for advice or search online for "replace crankset".

You can buy the unspecified gear you want anywhere that particular gear is sold.

Loosen rear axle nuts.
Pull back on the rear wheel until the chain is tight, then move forward just a bit and tighten both sides with your hands at the same time. Try to keep the wheel centered.
Tighten the right axle nut, center the wheel and then tighten the rear.
Turn the crank slowly. The chain should have slight play at the tightest point in the crank rotation.
If the chain is too tight or too loose loosen the right nut and move the axle forward or back, tighten and retest.
When tension seems OK loosen left nut and center the wheel, then retest.
