Major design Flaw in Mavic R-Sys
Annecy, January 5th 2009.
As part of its ongoing commitment to customer safety and satisfaction, Mavic has announced a voluntary recall of its R-SYS front wheels as a precautionary safety measure.
Mavic has identified that the carbon tubular spokes of the R-SYS front wheel may break during use in certain circumstances and causing the rider to lose control and possibly fall, potentially sustaining injury.
All models of Mavic R-SYS front wheels are concerned (R-SYS, R-SYS test, R-SYS Premium), whether purchased separately or as part of a bicycle. The wheels must no longer be used.
Consumers should immediately return their front wheel to a Mavic dealer; and a new upgraded R-SYS front wheel will be delivered free of charge. This exchange will start from 31st of March 2009. Until this date, and to facilitate the continued use of your bicycle, Mavic will offer a set of Aksium wheel that customers will keep after they have received the replacement R-SYS front wheel.
For any further question, please ask your Mavic Dealer,

for USA and Canada: 1-800-664-9228
