SUMMUM CARBON R MX

£200

The SUMMUM CARBON R inherits all of the features from the CARBON RR but with more affordable components. It shares the same frame as the CARBON RR, and also offers the MX option with a 29" front wheel and a 27.5" rear wheel. Light and effective, it's a great bike for podium finishes in any DH race. In this case the geometry change kit is optional.
