  14. Alternative product: 34 mm Fork Seal Kit Low Friction Flangeless (Manitou)

    Kit includes 2 high quality Trelleborg Flanged seals, 2 foam rings and Slickoleum grease.
    Fits 34 mm stanchioned Manitou forks from 2006 to present.
    Flanged type for 44mm pocket.
    Special compound for low friction & extreme low temperature performance

    These flanged seals have the same fork compatibility as the flangeless option.
    Flangeless seals provide a tighter fit into the lower leg (to resist popping out with internal air leaks) which makes them more difficult to install than flanged seals.
    A seal press tool is not essential for installation of the flanged seals but it does make the job easier.

    Flanged type for 44mm pocket.
    Special compound for low friction & extreme low temperature performance.

    These flangeless seals have the same fork compatibility as the flanged option
    Flangeless seals provide a tighter fit into the lower leg (to resist popping out with internal air leaks) which makes them more difficult to install than flanged seals
    We recommend the use of a seal press tool for installation to keep flangeles seals straight and set depth correctly.
