Review on 🚲 Bikehand Bicycle Bike Chain Wear Indicator Tool Chain Checker – Compatible with Shimano Sram KMC and All 7-12 Speed Chains: A Must-Have for Bike Maintenance by Dino Burks

Don't be a fool and check your chain and then kick yourself spending a few hundred on a new transmission if you could catch it with this tool for 6 dollars. Bikes are expensive and a little preventive maintenance can save you a lot of money. If you're looking to buy a used bike, grab one and take it with you when you look at it. If the chain is badly worn, you know that the gearbox most likely needs to be replaced, and therefore have the opportunity to act, or at least find out what you are getting into. This takes about 2 seconds. to test your chain with this thing and really takes the guesswork out of wondering if your chain is any good.
