How to repair a touring bike

Traveling bike, that is, no matter where you are going to ride it for wandering, so if it breaks down during wandering, how should it be repaired? The following tips and tricks for you to repair your bike will hopefully help you.

1. Shift cable tube rubbing the frame, grinding off a piece of paint, and putting transparent tape on the place of contact.

2. Adjusting the rear derailleur still doesn't improve the noise and inaccurate shifting. The flywheel locking ring may be loose, causing the flywheel blade to wobble slightly and make noise when turning. You'll need a special tool to tighten the locking ring sufficiently, but you can use your fingers to tighten it as much as you can, enough to ensure a safe ride home or to a nearby store.

3. The flywheel is rusty. A small amount of rust won't speed up the wear on the flywheel blades, so don't worry about it too much. Usually, a little extra lubrication will prevent continued rusting, and riding the chain until the rust wears off.

4. The pedals appear to skip teeth when using certain gear ratios. There may be something between the flywheels. If you can see clumps of mud, weeds, leaves, twigs or any foreign objects stuck in the flywheel, dig them out. These things prevent the chain from biting into the flywheel properly. If there's nothing there, this piece of the flywheel may be worn out. The presence of this usually indicates that the chain and flywheel need to be replaced.

5. The front derailleur won't shift accurately onto a particular cogwheel. Check to see if the guides are parallel to the cogwheel (viewed from directly above), loosen and reposition the front derailleur as appropriate. If parallel, you may need to adjust the high/low limit screws, preferably by a store or someone experienced.

6. The rear derailleur makes a constant spiking noise. The guide wheel is out of oil and needs to be lubricated. Lubricate from the side and wipe off the excess lubricant.

7. Brakes feel weak, although the brake blocks do not need to be replaced. The brake line may be stretched. Turn the brake trim nut counterclockwise (usually near the caliper or brake brake brake, at the end of the brake line pipe) to bring the brake block closer to the rim. Adjust according to what you are used to. There is a dragging sensation when braking. The braking surface of the rim may have grooves or small pits. Impacting the brake block on every lap is disconcerting. Take the car to the store.
