E*Thirteen XCX cyclo-cross chain device. The recent emergence of much wider gear ratios on either 10 or 11 speed cassettes mean that running a single chainring for cyclo-cross is a much more viable option. A single ring set-up has the obvious benifit of saving some weight, but also will not clog up with mud and water cause gear issues in the way that a double can. The E*Thirteen XCX chain device is a neat and very ligthweight (56g) device to make sure the chain does not derail in the absence of a front mech. It's bottom bracket-mounted, with a narrow 1.5mm backplate, which should ensure good compatiblity, and the nylon top slider offers loads of adjustment for a choice of chainring sizes, from 32-42t.
