So many cyclists ride their bikes with a worn out chain. Why?
The bicycle chain is a consumable part of the bicycle’s drive train and needs to be periodically replaced if you want proper shifting and smooth, efficient pedalling.
The main issues are most cyclists just don’t know their chain is worn out. Or, some cyclists know they should replace their chain after a certain amount of time and have no choice but to take their bikes into a repair shop for an expert’s opinion.
Remember, a worn out chain can quickly and prematurely reduce the life of the entire drive train. Chain wear causes the chain to mesh poorly with a rear cassette cogs and the front chain rings causing poor shifting and dangerous slipping. A complete drive train replacement is an expensive repair that could easily have been prevented.
So how can you check your chain to know if it needs to be replaced?
There are a few different ways to check chain wear but most require a certain level of expertise and experience where accuracy can be an issue. The easiest and most accurate way to determine chain wear is by using a tool such as the IRIDIUM Chain Checker. Having a chain checker tool in your home tool box is such an easy way to make sure you are not stuck with an expensive drive train replacement down the road.
The IRIDIUM Chain Checker is so simple to use and provides an accurate measurement on all 5 to 12 speed bicycle chains. The IRIDIUM Chain Checker has an easy to read scale from a 0% to 100% wear indicator. Once your chain reaches the 75% wear, you know it is time to replace your chain. (So simple, and yet so important)
Just insert the rear pin between any outer chain plates and the front pin between two inner plates. Push down lightly on the black swivel lever until it comes to a stop. The reading in the center indication line will tell you what percentage of wear you chain is at. It’s that simple! Once the wear indication line passes 75% it is recommended to replace you chain.
