Abbey Bike Tools

The LL Chain Wear Tool - which stands for Linear and Lateral - lets you measure the wear of any chain accurately, without being thrown off by either the larger roller diameter of flat top chains or by the extra lateral demands cross chaining with 1x drivetrains puts on the chain. SRAM drivetrains feature flat top chains with a roller that's .010" (.254mm) bigger than any before it, which when measuring five links of a chain, can cause chain wear tools to under measure wear by .2%. When replacing chains with between .5% and .75% wear is standard, this margin can mean the different between replacing just the chain or the whole drivetrain if a worn chain is allowed to impact the rest of the components. Meanwhile, cross chaining to get the full range out of 1x drivetrains will put extra wear on the faces of the rollers, over time degrading the shifting performance. The LL Chain Wear Tool is your solution for both of these scenarios. It is machined with a V-shaped notch in which to locate t...
