Mefo Mousse MOM 21/G-BIG Groove (90/90-21 and 90/100-21 Large Casing) Universal Tyre inner foamRef : MEFO00030A / 9004407

MEFO MOM 21/G-BIG Groove Foam — replacement foam designed by MEFO for 21" front wheels. Ideal for off-road riders looking for better suspension feel without changing their tires.

The Groove stands out with a longitudinally patterned carcass that offers targeted flexibility during compression and rebound phases. This specific geometry aims to enhance contact and response of the wheel on off-road trajectories while limiting the weight of the solution compared to bulkier blocks. The result: a sharper riding sensation and optimized suspension management for obstacles, jumps, and accelerations.
