XCX cranks do not come with Chainline spacers. Boost/non-boost configuration is achieved by selecting the correct offset chainring:
- XCX Mountain Cranks
- e*thirteen Guidering UL direct mount rings are -5mm offset which achieves boost 148mm chainline spacing.
- e*thirteen Guidering SL direct mount rings are -8mm offset which achieves non-boost 135/142mm chainline spacing.
- XCX Gravel Cranks
- e*thirteen Guidering UL direct mount rings are used to achieve 135/142mm chainline spacing as spindle length is reduced.
While our other carbon crank are supplied with crank boots, our XCX cranks are not. The goal with our XCX crank project was to achieve the lightest possible XC Crankset and therefore crank boots were omitted. The TRS/LG1 boots will not correctly fit the XCX cranks.
*Some crank packaging and manuals included with cranks indicated chainline spacers and boots are included. This is not correct and packaging and manuals are now updated.
