50mm (ID) Nylon Lock Stop Saver. These are now made from WHITE nylon. They have been cut from a water and as such have a slightly rough finish to them.These universal lock stops fit around your fork tube and can be rotated to vary the amount of lock on the steering by placing the large cam in different places. They can save Frame damage and damaging the lugs on the yokes in the event of a crash, or can be used (most popular application) to reduce the lock on Track/Race bikes. They are universal and on some larger fork tubes a degree of fitting maybe required - we also supply longer bolts just in case!
