SRAM 10-Speed PowerLock chain connector links are being recalled by the company. The recall pertains to 10-speed PowerLocks, not chains. PowerLocks stamped with "M" and "N" dated codes are targets of the recall. If your are using these links stop doing so immediately, as a failure could cause a dislodging of your bike chain. If for some reason you have modified a chain using one of these links on a fixed gear bike (a chain made for a 10 speed will ordinarily be too long for use on a fixie unless links are removed) the danger may be especially great. A dislodged chain on a fixed gear bike can be catastophic since the chain plays a pivotal role in stopping the bike.
