The best 10mm locking rings on the market
Polini has cracked the code and has produced fantastic locking rings to hold the cross pin and piston, which are easy to mount thanks to the design which gives two ears you can catch with pliers and insert into the piston.
You get two pieces in this set, and for the price you will not find better. They are strong, easy to assemble and best of all, they are inexpensive.
NOTE: This set is for ø10mm cross pins and pistons.
