스크랩 샥의 증상과 조치방법

[탐험가(박종수)]

Not using full travel, feels harsh, poor traction while making turns

CAUSES

Overly stiff springs or compression damping

SOLUTIONS

Lower air pressure; reduce compression damping; softer coil springs

Bottoms, soft throughout travel

CAUSES

Spring rate too low throughout travel, or too little compression damping

SOLUTIONS

More air pressure; increase compression damping; stiffer Coils Springs

Excessive sag, feels soft initially but doesn't bottom

CAUSES

Initial spring rate or preload too low; spring too progressive

SOLUTIONS

Add air pressure or increase spring preload

Harsh over small bumps but uses full travel

CAUSES

Initial spring rate or preload too high, springing not progressive enough, or too much compression damping

SOLUTIONS

Lower air pressure or install softer springs; reduce compression damping; reduce spring preload

Takes first bump in a series well but harsh over later bumps, poor traction in washboard corners

CAUSES

Too much rebound damping

SOLUTIONS

Reduce rebound damping if adjustable - Non adjustable - reduce oil weight

Too Much Compression

SYMPTOM

Ride is harsh, but not as bad as too much rebound. As speed increases, so does harshness. Rear end will want to kick when going over medium to large bumps ( shock resist movement even on medium size bumps)

SOLUTIONS

Decrease compression until harshness is gone

TIP

To learn what damping can do for your ride, experiment with the compression adjustments and rebound adjustments ( if your shock model has them ). We suggest you start with compression damping... Turn compression adjuster (blue knob Vanilla RC & Vanilla DH only) to full firm ride your bike for awhile and then turn the adjuster to full soft. This will give you an idea what compression damping can do. Like wise do the same with your rebound adjusters..... Feel what fast is ..... Feel what slow is

Wheel chatters over small bumps during braking or downhills

CAUSES

Too much preload (perhaps because of soft springs) causing suspension to top out; possibly too much compression damping

SOLUTIONS

Reduce preload decrease compression

Takes first bump in a series well but harsh over later bumps, poor traction in washboard corners

CAUSES

Too much rebound damping

SOLUTIONS

Reduce rebound damping if adjustable - Non adjustable - reduce oil weight

Front end springs back too quickly after bumps, poor traction in bumpy corners

CAUSES

Not enough rebound damping

SOLUTIONS

Increase rebound damping if adjustable

Rear Tuning tips

TIPS

There are three major adjustments for FOX Racing Shox for Bicycles: Springs / preload, Compression damping, Rebound damping. The spring preload sets the ride height of the bike and determines how much of the total travel will be available for compression and how much will be available for extension. Damping keeps the bicycle from behaving like an old Sacked out Cadillac - i.e., still bouncing 10 seconds after hitting a bump. Compression damping slows the shock when it is being compressed. Rebound damping slows the shock when it is rebounding.

Spring preload Tips

TIPS

PreLoad is adjusted at the shock body ( silver knurled ring ) Shaft sag setting too much - Increase preload - maximum two full turns. In many cases you will need to purchase a new spring for correct sag settings. Set up your bike correctly to keep repair cost down ! Shaft sag setting too little - Reduce preload or use a softer spring.

Fox rear shocks spring preload warning

WARNING

If you need more than two turns of preload you will need a higher spring rate. To much preload will cause the spring to coil bind and in some cases damage to the shock may result. Typical coil bind dam-age - Vanilla RC body end caps cracked or broken and Pre-load and spring retainers bent or broken... and in some cases bent damper shafts.

Not using full travel, feels harsh, poor corning and braking traction

TIPS

Overly stiff spring rate or compression damping, possibly too much PreLoad

Shock Damping Adjustment Locations

TIPS

Rebound adjustment (if applicable) is located at the shaft end of rear shock ( red knob ). Compression adjustment (if applicable) is located at the top of the Vanilla's reservoir (Blue Knob). The Float RL and the Vanilla RL have a blue compression damping lock out lever.

Too little Rebound

SYMPTOM

Ride the bike slowly off a curb and if you get after bounce ( Boing, Boing, Boing) you will know the setting a little to fast

SOLUTIONS

Increase rebound "gradually" until the wallow is gone and after bounce from curb drop gone

Too Much Rebound

SYMPTOM

Ride is harsh, suspension control is limited and traction is lost. Rear end will pack down, forcing the suspension of the bike to skip over bumps instead of following the terrain

SOLUTIONS

Decrease rebound "gradually" until harsh ride is gone and braking traction is regained. This will also keep the rear suspension from packing down

Rear shock lack of Compression

SYMPTOM

The rear suspension will feel too active (bounce and wallow excessively) After big jump landings the shock bottoms to easy

SOLUTIONS

Insufficient compression - Increase compression "gradually until the balance / feel is optimized. You will notice better control over the Bounce and wallow symptoms
