**Warning: EPS Groupsets will not work with 11/29 ratio cassettes. Use 12/29 instead.**
In competition every little detail counts; that's why steel and titanium were used when producing Record sprockets.
The perfect teeth design results in a perfect synchronization between shifting and chain movement.
The six larger sprockets are divided in triplets, which are mounted on special frames to increase rigidity.
* 8 steel sprockets
* 3 titanium sprockets
* nickel-chromed finish for steel sprockets
* light alloy carrier
* light alloy supports for the final two triplets
* 11x timing
* 11x tooth machining
* 11x light alloy lockring
* Thread 27 x 1
* Weight 201g
