Trek Scratch Suspension F.A.Q.

How do I properly adjust the Trek Scratch suspension for my weight?

To adjust the Trek Scratch suspension for your weight, start by setting the sag. Wear your full gear, and use a shock pump to adjust the air pressure until the sag is about 25-30% of the total suspension travel. Check the manufacturer's guide for specific pressure recommendations based on rider weight.

What is the recommended maintenance schedule for the Trek Scratch suspension?

Perform basic maintenance such as cleaning and inspecting the suspension after every ride. Every 25-50 hours of riding, check for oil leaks and lubricate the seals. A full service including oil change and seal replacement is recommended every 100-200 hours, depending on riding conditions.

How can I troubleshoot a squeaky noise coming from the suspension?

A squeaky noise may be caused by dry or dirty seals. Clean the suspension thoroughly and apply a small amount of suspension lubricant to the seals. Check for any loose bolts or worn-out bushings as well.

What should I do if my Trek Scratch suspension feels too stiff?

If the suspension feels too stiff, reduce the air pressure in the shocks slightly and adjust the rebound setting to a slower speed. Ensure that the suspension is properly lubricated and check for any obstructions that might restrict movement.

How do I replace a damaged suspension seal on my Trek Scratch?

To replace a damaged suspension seal, first, release all air pressure and remove the suspension from the bike. Carefully remove the old seal using a seal puller tool. Clean the area thoroughly and install the new seal by gently pressing it in place, ensuring it is seated evenly. Reassemble and test for leaks.

Can I upgrade the suspension on my Trek Scratch, and if so, how?

Upgrading the suspension is possible. Check compatibility with your frame and select a suspension that matches your riding style. Consider consulting a professional mechanic for installation to ensure optimal performance and safety.

What type of lubricant is recommended for Trek Scratch suspension maintenance?

Use a suspension-specific lubricant to maintain the seals and bushings. Avoid general-purpose lubricants as they may degrade the materials. Always follow the manufacturer's recommendations for the best results.

How can I quickly check if my Trek Scratch suspension is functioning properly?

Perform a bounce test by pressing down on the bike while it's stationary to ensure smooth and even compression and rebound. Listen for unusual noises and check for any oil leaks around the shock area.

What signs indicate that my Trek Scratch suspension needs servicing?

Signs that your suspension needs servicing include reduced performance, unusual noises, oil leaks, and excessive sag. Regular checks and adherence to the maintenance schedule can prevent these issues.

How do I set the rebound on my Trek Scratch suspension?

To set the rebound, locate the rebound adjustment knob on the shock. Turn it clockwise for a slower rebound and counterclockwise for a faster rebound. Test different settings to find the one that offers the best control and comfort for your riding style.
