The ICE chainring guard is a light weight and durable unit made from heat treated Al Alloy. The guard is an added safety feature but is also very good in preventing you from accidentally brushing against the oily chain rings and avoiding the recumbent rider tell tale prints on your legs or trousers.
The guard is fitted without removing the chain set by clamping the guard to the bottom bracket shell. A chain ring of up to 58T can be used.
Can be used on some other brands. Inquire before ordering for fit confirmation.
