For purchase is a Cartridge and Internals Replacement Kit to upgrade the performance of your 41.7 mm M1R Forks. This is a complete kit and will allow you to replace all of the original internals of your Marzocchi M1R forks for upgraded race kit.
Currently, our kits are available for the larger 41.7 mm and 41 mm Marzocchi M1R forks. If there is enough interest we could take a look at building kits for the 35 mm forks. However, currently, we are not able to offer for the 35 mm forks.
We do ship internationally and share my deep discounts with the various shipping services.
