Proper Frame Sizing

Standover Height

Most K2 Bike frames are offered in four sizes. We design our bikes with as low of a standover height as possible. When sizing a frame, a minimum of three inches of clearance between the rider's crotch and the top tube of the bicycle is required. This room is needed due to the uneven terrain encountered when riding off road. The three inches should allow you to hop off of the pedals and straddle the top tube safely in a panic situation.

Correct Standover Height


Warning: Riding a frame that is too large or too small can lead to loss of control and injury.

Saddle Height and Position

You should adjust the height of your saddle to accommodate your leg length. When seated on the bicycle in a normal riding position, your knee should be slightly bent at maximum extension (pedal at lowest point). To set this height, sit on the bike and place one heel on a pedal. With the pedal at its lowest point (the down position), you should just be able to touch the pedal with your heel.

Raise or lower the seatpost by loosening the post binder bolt or using the quick release as you would a front or rear wheel quick release. Under no circumstances should the seatpost extend from the frame beyond its ”Minimum Insertion“ or ”Maximum Extension“ mark. On some K2 Bike models there is a maximum height hole on the back of the seat tube or seatmast. Do not extend the seatpost beyond this hole.

Correct Saddle Height


CAUTION: Adjusting the seatpost higher than the maximum height mark on post, or maximum height hole on frame can result in failure during use and severe injuries.

It is also possible to adjust the seat fore and aft, or to adjust the angle to enhance individual comfort. We suggest you start with the saddle in a middle position with the seatpost clamp centered on the seat rails, and with the top of the saddle level with the ground. Very small changes to saddle can have a substantial effect on comfort and performance. Consequently, whenever making changes to saddle position, do so in small increments until you have found the most comfortable position. Be sure to tighten all bolts after adjustment has been completed.

Handlebar Height and Reach

Saddle Position

Your K2 Bike is equipped with a stem which clamps on to the outside of the steerer tube of the fork. The height of this stem may be changed slightly by adding or removing headset spacers. If you need to adjust your handlebar position beyond these small adjustments, you'll have to get a longer or shorter stem with a higher or lower rise. Another option is a different handlebar with a different rise. Consult your dealer for any changes that you may feel are necessary. Be sure to retighten all bolts after adjustments have been completed.

Control Position

The brake and shifting controls on your bike are positioned where they work best for most people. The angle of the controls and their position can be changed. Ask your dealer for help with this adjustment.

Many bikes have brake levers which can be adjusted for reach. If you have small hands and find it difficult to squeeze the brake levers, your dealer can adjust the reach for you. Your brakes will require readjustment of the reach adjustment is changed. Refer to Maintenance : Brakes for more information on adjusting your brake levers.

Important: This is not a comprehensive maintenance checklist. If you suspect a problem with your bicycle, do not ride the bike until the problem has been corrected. If you are uncertain about the cause of, or how to correct, a problem, consult your authorized K2 Bike Dealer.
