The new Mudhugger EVO is designed around the latest FOX 36 and 38's and Rockshox ZEB to avoid the problem of the crown hitting the mudguard at full compression that other mudguards suffer from (adapter bracket required for ZEB, see options) but still compatible with older (2017 onwards) FOX forks 34 and 36 (including Fox/Marzocchi) which have bolt holes. *not compatible with Marzocchi Bomber Z2 (no bolt holes in fork brace).For 2022 onwards Fox 34 you'll need to use the Quick Fit Kit For Front EVO Mudhugger kit as the fork brace is hollow and the bolts have very little to tighten to.Sadly the Fox 34 stepcast fork is too narrow to accept the EVO Mudhugger.More mud clearance.No more crown fouling at full compression.Optimum length, not too short, no longer than needed.Subtle kicker to keep the length as short as possible without compromising spray protection. Strong enough for DH racing at the highest level.100% recycled PP.Length - 390mm total - Rear extension 255mm, front extension 105mmWeight 100g, without fittings.PLEASE ENSURE YOU USE THE HELITAPE PROVIDED WITH MUDHUGGERS. INVISIFRAME OR ELECTRICAL TAPE ARE NOT SUFFICIENT TO PROTECT YOUR BIKES PAINT AND FRAME.
