SERVICE NOTES FOR DUAL SUSPENSION
  • While the 4-Bar linkage system is very torsionally rigid and requires less maintenance than a single pivot design bearings and bushings will wear out. Bushing kits and replacement rear stays are available from Kona Mountain Bikes for all suspension frames.
  • Cartridge bearings give the suspension a smoother ride. These bearings also require more attention than do bushings. Contaminated bearings can rust & seize, and cause frame damage. Regularly inspect the bearings and make sure that they allow the linkage to move freely.
  • Whenever there is a pivot with minimal movement it is sometimes better to use a bushing. Bushings tend to be lighter and require less maintenance. They should still be checked and lubricated at regular intervals
  • Front suspension should be checked and serviced as per manufacturers Owners Manual.

SET-UP NOTES FOR SUSPENSION

FRONT SUSPENSION
For 2007 Kona models use a variety of suspension forks. Travel ranges from 1.2" to 7.9" depending on the model. For any suspension fork you have to adjust sag in order to get the best performance. Fork makers suggest that the sag measures ¼ of the total travel. Sag for all suspension forks can be measured the following way:
  1. Make sure that the stanchion protectors (dirt boots) won't interfere with your set-up. They can be removed or one can be zip strapped to the top of the stanchion tube right under the fork crown.
  2. Install a zip strap around the stanchion and slide it down until it makes contact with the dust seal located at the top of the fork leg.
  3. Sit on the bike with your feet on the pedals. Prop yourself against a wall. Do not bounce on the pedals or the saddle.
  4. Carefully get off of the bike without bouncing or compressing the suspension.
  5. Measure the distance between zip strap and the black seal to get the sag . Decrease sag by increasing the forks pre-load (turn knobs clockwise) or increasing the forks air pressure, increase sag by decreasing pre-load (turn knobs counter clockwise) or decreasing the forks pressure. Refer to chart below for recommended sag.

REAR SUSPENSION
Owners should look at manufacturer’s manual to determine features and adjustments that will aid in the performance of their rear shock. For any rear suspension it is necessary to adjust sag in order to get the best performance. Set-up is done best when you have someone that can help you.

  1. Refer to Suspension Set-Up chart to determine the eye to eye w/o rider measurement. This is the linear distance between the upper and lower bolts that attach the shock to the frame. Check to make sure that the bike has the correct length of shock.
  2. Sit on the bike with your weight in a neutral position (centered). Have an assistant measure the distance between the upper and lower shock mounting bolts (eye to eye w rider sag). For a good starting point, you want to match the measurement listed in the eye to eye w rider sag column.
  3. To increase the eye to eye measurement, add air pressure on Float shocks or tighten the pre-load spring on Vanilla or DHX shocks. To decrease the eye to eye measurement release air pressure (Float) or loosening the pre-load spring (Vanilla / DHX).
  4. Repeat steps 2 - 3 until proper sag is achieved.

FOX SHOCK TERMINOLOGY

  • Travel: The total amount the shock compresses
  • Shock Sag: The amount the shock compresses with rider sitting on bike in normal riding position. This is usually 15% to 25% of total shock travel. Cross country: 15% to 25% suggested, Downhill 25% suggested
  • Compression Dampening: This controls the rate at which the shock compresses
  • Rebound Dampening: Rebound dampening controls the rate at which the shock will extend
  • Preload: The initial force placed on a spring
  • Spring Rate: The amount of force required to compress a spring one inch
