Le Tour Chainring Spacers

0.6mm spacers are ideal for retrograding Campagnolo 10 speed chain rings for use with 6,7,8 and 9 speed Campagnolo drivetrains. 

Simply place a 0.6mm spacer the BACK of the outer chain ring. If you have a Record 10 speed chain ring remove and discard the 0.4mm Campy spacer that sits between the FRONT of the ring and the crank arm. 

Use two kits to retrograde a Campy 10 speed triple crank set. Place Le Tour 0.6mm spacers on the BACK of the outermost ring and on the FRONT of the innermost ring. 

Use the spacers to widen the space between your front chain rings to improve shifting. Reduces chain rub on the inside of your outer ring when you are in a 39/12 or similar small ring/smallest cog combination. 

Le Tour makes two different inside diameters for their chainring spacers; female and male. The female inside diameter is larger and designed to fit precisely around female chainring nuts. The male size has a smaller inside diameter and only fits around male chainring bolts. 

Female spacers are 0.6, 1.2, 2.0 and 3.8 mm thick and packaged as a set of five. They will fit Campagnolo, Shimano, Sugino, SR, Sun Tour and most other brands of chain rings and chain wheel nuts. 

Male spacers are 2.2, 3.0, 3.5, 4.9, 4.3, 4.6, 5.0, 5.3, 7.1 and 8.3 mm thick and packaged as a set of five. They are widely used to properly space the innermost ring on a three ring crank.
