When Should I Replace My Bike Chain?
Chains are a consumable part of the bicycle drive train. As you pile on the miles, your bike’s chain will wear out. The internal parts of the chain, the rivets and rollers, begin to wear and give the illusion of stretching. This wear can cause the chain to mesh poorly with cogs and chainrings, causing poor shifting, premature wear to the cogs and even skipping over the cogs.
Since it’s far more expensive to replace your cassette than it is to replace a chain, knowing when to replace your chain can actually save you some money in the long run.
Remember, using a chain beyond its intended wear limit will prematurely wear out your cogs and chainrings so staying on top of this routine maintenance task can save you a lot of cost and hassle in the long run.
