The ultimate chainset, the XTR’s are simply stunning. So too is their price tag unfortunately, but quality of this standard costs money. The XTR’s are fiendishly lightweight and deceptively strong, dealing with all trail duties with ease. While they are not designed for freeride or downhill duties we have seen plenty of riders run them on the World Cup circuit looking for that extra weight saving. In their standard triple ring set up the shifting is unrivalled and those chainrings are unbelievable light, seriously you have to hold one to believe it!
