【Scope of Application】 Telescopic spring piston in the hole (or groove), can conduct inner diameter detection, used with micrometer or caliper, with knurled locking device..
【Unique Design】 The spring tension of bore measuring tool gives uniform contact pressure, can detect the inner diameter in a hole (or groove).Spring of telescopic gauge loads with knurled locking knob and knurled holding area..

For use with Martin taper bushed, QD and stock, and finished bore roller-chain style couplings (sold separately).
Aluminum provides corrosion resistance and minimal additional weight to the coupling.
Synthetic rubber seals along the bore keep lubricants contained and keep contaminants out.
Two halves to facilitate installation, and has gaskets between the halves to prevent lubricant leakage or debris intrusion between the halves.

Hyper glide sprockets have a computer designed tooth configuration with contoured shift gates.
Close ratio gearing allows a more efficient use of energy through finer cadence control.
Sprockets are cut away to further reduce weight without reducing rigidity.
Nickel-plated finish offers hard wearing resistance to corrosion.
