Last time, we shared a timeline for damage to worn parts. Let's continue to see what else is worth our attention this time.
6 months
- Check the bearings and bolts for abnormal wear
This may require special tools because the bottom bracket requires a cup tool.
- Learn how to find warranty problems and complete them before they expire
The time between buying the bike and the warranty expires is valuable. If there is a problem, don't delay contacting after-sales for a long time.
- Check the chain/sprocket for wear
Most riders will use the chain for about a season and the rest of the drivetrain for several seasons. Replacing the chain before it wears out can prevent the rest of the parts from wearing out prematurely. For most riders, six months is a good time to check.
- Check the cable and housing for wear
A worn housing (outer lining) looks thinned, kinked, or worn inside the ferrule.
A worn shift cable (inner cable) is kinked or worn. If any of these symptoms occur, they should be replaced.
—If the front or rear doesn’t feel good, bleed the brakes
Hydraulic brakes that use DOT fluid will degrade quickly and do better if bled a few times a year. Brakes that use mineral oil can run without oil seepage, although the fluid level will change as the pads wear.
—If the wear is below the thickness of the return spring, or anywhere near the backing plate, replace the pads
—If using tubeless, add any new sealant if you haven’t done so by now.
More than one year
—Replace the chain if approaching a full season of use
The lifespan advantage to the rest of the drive train is worth it. Also, consider a chain checker to ensure you never ride a worn chain.
—Replace worn housings
Even if your shifting feel is still good, you’ll be surprised how much better the new cables feel.
—Replace pads/check rotors, especially if you’ve replaced the pads.
Most rotors should be able to handle four to six sets of pads, depending on the compound used. However, if your brakes feel more worn, new pads and new rotors will make them feel like new no matter how you adjust or bleed them.
— Check tires for wear and small cuts
If a tire has flat spots or is deformed, replace it immediately. If it is a tubeless tire, pull the tire off and check for embedded debris.
The sealant may have sealed this debris around without your knowledge.
