    over forking and shock extending 2018 or 2019 altitude

    Has anyone got a 2018 or 2019 Alititude with a longer stroke shock and/or longer fork setting? I'm interested in whether they can be made to work (safely) at 160mm rear 170mm front.

    I'm interested because I have a 2016 altitude and keen to upgrade soon. I use it primarily as an enduro bike, and occasional bike park

    I want something to deal with nastier and steepr trails better, a bit longer, slacker and with more travel. More modern geo, without the more modern wheelsize. Have demoed a few 29er enduro bikes and don't like em so much. I'm a bit short and get the butt buzz and so forth. And it doesn't generally feel great.

    So was wondering if a viable solution could be a new altitude with travel extended.

    I have a 2018 with a 170 fork, itís fine.
    The Ď16 and newer have the same wheel size, 27.5.
    Or did you mean tire size?

    If you're talking current platform you can run 170mm fork. You can probably even extend the fork it came with depending on model.


    Using offset bushings and only going in the slackest ride 9 position you can run an 8.5*2.5 shock. Check out Remi G's bike check from a few years ago. This'll put you at around 170mm rear though.

    Yes, I just got a 170 air shaft for the existing 36. Piece of cake.

    are they all imperial size shocks? anyone know which year they moved to metric? 170mm rear end could be a bit much, not sure.

    don't mind making the bike slacker (would prefer), although not so sure about making the BB heaps higher.

    i did run some offset bushings on another bike so familiar with that

    The offset bushings when switching to the longer shock help keep the BB in check, as will running more sag (as a true distance rather than strictly a higher percentage) . I doubt you'll have problems with BB height.


    The 2017-2020 (current platform) is metric shock sizing.


    If you're on the previous platform I know nothing about over forking and over shocking it.
