Building on the award winning, tried and tested Rear Mudhugger design, we have now added 3 signficant improvemnts over the original 2012 Rear Mudhugger design.1. Utilising reusable quick release velcro straps to fit to the helitape protected seat stays makes fitting and removing a matter of seconds.2. Where the Mudhugger 'sits' on the seat stays we have incorporated rubber inserts which aid grip and improves damping.3. An all new push fit BB extender. Designed to protect bearings and the BB area from mud and debris build-up, in even the most extreme conditions.
