    170mm Fork on Ripmo?

    Anyone running a 170mm fork on their Ripmo?

    I have heard that this is how Robin Wallner runs his race bike and I think it would bring the bike more or less totally in line with who I want it to be - slightly slacker, bit higher BB but not loosing too much on the STA.

    Yep, running a 170 36. Also have a 160 with the Grip damper. There is a slight difference, but not massive. Still handles and climbs well with the 170.

    When I asked Ibis if they had some off-the-shelf geometry numbers for the Ripmo @170, was told by Chuck himself to keep the max front travel on the Ripmo to 160mm. So it would seem that 170 is not encouraged by Ibis.

    Unless he's changed since Feb, Robin is running 160mm with an angle set. He said he feels the 170 would not be balanced with the 145 rear.

    I did it, but it was because I was running the luftkappe. With the luftkappe the front sat about 5-6mm into travel with just the weight of the bike.

    Debatable. Reach isn't shortened as much with the angle set, stack is not changed, bb height gets slightly lower instead of higher, STA steeper instead of slacker. HA and WB are approx the same between 170 fork vs. angle set, so it really depends what you are looking for.

    I'm running a -1 angle set on my Ripmo and it's great. I would be interested to try the angle set AND the 170 fork because those numbers look pretty spicy on the geometry calculator

    I have the 170mm fork on my ripmo and works great, now looking for an angle set to slacken it a bit so it is more balanced.

    What did you notice when switching to the Luftkappe?

    I’ve luftkappe’d both of my 36s. Amazing upgrade. The small bump chatter that the fox forks are always talked about having is gone. Even with the new EVOL air shaft, luftkappe makes a noticeable improvement.

    170mm Fork on Ripmo?

    I’ve already removed the single volume spacer from my 2019 36 when I converted from 160 to 170 shaft. Luftkappe suggests removing 2 tokens from your pre Luftkappe setup.

    I would definitely benefit from small bump and early stroke compliance, but it sounds like the effect of Luftkappe installation will be like adding two VS. that will be way too fast ramp up mid stroke. At least this is my assumption.

    Experience with zero VS pre and post Luftkappe install?

    Anyone not happy with 170 mm that has gone back to 160 mm? Looking for a new fork and can not decide between 160 or 170 mm.

    Depends on how you ride it. If it is mainly a trail bike, stick with 160 and stock HA. If it is mainly a shuttle / gravity bike with fire road climbs to get to the trail head, go 170.
    I have tried both, 160 is nicer for flattish trails and techy climbs.

    It’s just a $40 airspring assembly. I swapped mine to 170mm, I definitely like it. Doesn’t turn as quick, which was expected, so at first I was running a tad wide on exit of corners, but got it dialed pretty well.
