New Abbey LL Chain Put on Device Measures Each Lateral & Linear Put on

Ever run right into a state of affairs the place the chain didn’t shift effectively, however your chain checker stated the chain wasn’t worn out? If you happen to’re operating a contemporary 1x drivetrain, Abbey Bike Instruments says that there’s a good probability that lateral, not linear, put on is the offender.

As 1x drivetrains have taken over and cassettes have gotten wider, that has pressured riders to basically cross chain on the extremes of the cassette. The angle of the chain then causes additional put on to the faces of the rollers which degrades the shifting over time. In accordance with Abbey, “Relying on situations and driving fashion this may occur effectively earlier than a series has reached alternative thresholds for linear put on, generally referred to as stretch. Whereas chains which have worn out laterally gained’t trigger undue put on to the remainder of the drivetrain, shifting efficiency positively suffers.”

So when the precision device maker needed to develop their very own chain put on gauge, they knew it needed to embody each lateral and linear measurements. That’s the place the brand new Abbel LL Chain Put on Device is available in. The precision device is machined from a single block of 6061 aluminum of their CNC mill. That enables for tolerances as tight as 0.00025″ which is able to influence chainwear measurements by 0.004%. In comparison with chain put on measurement instruments which are manufactured with CNC laser cutters, Abbey claims the CNC milling technique ends in a extra correct device.

Additional accuracy on the linear chain put on facet is assured by a V-shaped notch that locates the curler. When SRAM launched their Flattop chains, they included rollers that had been 0.010″ (0.254mm) bigger which is sufficient to skew the measurement on present chain put on instruments. How a lot? Abbey claims that when measuring 5 full hyperlinks, a standard chain device would underreport put on by 0.2%, which “with fashionable drivetrains that’s the distinction between changing simply your chain and your entire drivetrain.”

As an alternative, the V-notch locates the curler no matter measurement ready the place the middle of the pin is the true origin. You then merely line up the pin with a gap on the opposite finish of the device to measure linear put on.
