e*thirteen xcx chain guide

More and more customers are deciding to build or convert their mountain bikes to 1×9 or 1×10’s.  The conversion is pretty darn simple, but you do require some sort of chain guide to keep the chain on the single front chainring.  Enter the XCX Chain Retention System.

The XCX, by e*thirteen, has won the Men’s Elite Silver medal in the 2009 UCI World Championship Cross Country race and is the first chain retention system in the world to podium at a international World Cup XC event.

The bottom bracket mount model pictured here has a pretty close to universal fit, and is even indexed to tell you exactly how to set it up based on the number of teeth you’re running on your front ring.  It’s also available in white, and there’s a seat tube mount version if you’d prefer.  We have a handful in stock now for $45 a piece, so get building that 1×10 now!|
