Designed by ICE, this optional chain ring guard is a light-weight and durable unit made from heat treated aluminium alloy. The guard is an added safety feature but is also very good at preventing you from accidentally brushing against the oily chain rings and avoiding the tell-tale prints on your legs or trousers.The guard may be fitted without removing the chain set by means of its convenient 2- bolt fixing. A chain ring of up to 58 tooth size can be fitted.
