This is the e.thirteen XCX+ Chain Guide. This chain guide is the brainchild of an e*thirteen World Cup mechanic, the XCX Chain Retention System has literally been years in the making. The XCX+ has been regularly used and abused by friends and employees of e*thirteen since 2004 and has been proven at the highest levels of competition right out of the gate. Having won the Men's Elite Silver medal in the 2009 UCI World Championship Cross Country race, the XCX is the first chain retention system in the world to podium at an international World Cup XC event.
The XCX+ chainguide is an XC chain device specifically deigned to be used on a single front chain ring and with either a 9 or 10 speed cassette at the rear. The super lightweight design (only 56g) allows you drop your chain rings down to one and take off your front mech and front shifter further saving weight. E*Thirteen have extended the XCX range this year to include ISCG 05. Usability is also a great addition to this chainguide. You can easily change chains and chainrings without removing the wearplate. The Wearplate also has chainring size indicators for simple adjustment. 1.5mm backplate spacing with 0.5mm spacers for perfect set up.
