A Quick Guide to Bike Chain Repair

A basic repair that every bicycle enthusiast should know how to perform is a chain repair. Rocks, sticks and the like that come in contact with the chain will typically cause it to jump off. On the other hand, if this happens repeatedly or occurs when pedaling normally or when riding at a fast pace, something may be wrong.

Start by examining the rear wheel to make sure this is in alignment. While riding, this can be difficult to see as you will have to turn around to observe, so a friend riding behind you is always a viable option. If one is not available, turn the bike upside down and pedal with your hand to check for any wobbling. Look over the derailleur to make sure it is properly aligned as well, since this is another make factor of a repeatedly popped chain. The last area to check is the teeth on the sprocket to make sure they are not worn and also the chain itself so that it is properly lubricated with neither too much nor too little grease.

Once you do realize that the chain has popped, stop immediately to prevent hooking on a stump or other debris. If the chain has slipped off the front sprocket, lift the rear tire off the ground and slowly start pedaling with your hand. The chain, with a little help, should lock back onto the sprocket.

If the chain slips off the rear sprocket, which is more frequent, it is almost the same process. I typically turn the bike upside down to have a better angle. Lay the chain over the rear sprocket and make sure the chain stays taught with the other hand. It does not matter which section of the sprocket you lay the chain on, as you will shift to the desired gear after the chain is completely back in place.

A bit of practice will have you back on the road or trail in no time. Again, if this happens repeatedly, check the rear wheel, derailleur and teeth. A chain that is too tight or too loose may cause repeatedly popping and this can be fixed at home with a chain tool or at a local bike shop. Keeping your hands clean is near impossible with chain repair when dealing with a properly oiled chain. Soap and water takes care of this problem.
