    Foes FXR ISCG replaceable mount doesnt fit

    I have an email in to Foes, but in the mean time I would see if anyone else has seen this.


    2010 FXR, replaceable iscg05 mount, 'dont fit!:

    I got to talk to a guy at Foes and he said that the frame isnt designed to work with the iscg plate. Does anyone else have an FXR that does work? I'm curious to see any differences in these. Thanks!

    Well, despite the issue, I decided to take it to the next level. To get the ISCG tab to work here, you need to remove part of the webbing on the rear triangle to get that mount to sit. I did a rough cut to sink it down and its been working. This is extremely rough and graphic, yes I cut into the frame, yes I know it could cause future failures, no I'll never sell it to pawn it off on someone else, I love this frame and NEED this to work properly. As you can see in the one picture, I loose the chain into the inside of the crank set and is gouging it fairly bad, that alone set me off and now I just dont care any more, so here's what I have. I also "modified" aka hacked an E13 LS1 chain guide to work with this setup. I'm probably going to revisit that and try different guides out to see if they'll work better. I also need to change the bottom roller to a fat rubber one instead of the sliding roller. I've ridden it and its worked fairly well so far.

    Mine fits: Foes-specific ISCG '05, splined, replaceable thingy.

    However...even tho the ISCG mount does fit, I have yet to find an actual chainguide that is usable when bolted on, usually coz the lower section of the guide fouls the chainstay of the swingarm. (Seems kind-of pointless why they made the ISCG mount...altho Foes did have Gamut make a custom design that works with the 'dropped chainstay' design on the Foes swingarm)

    That's why I ended up using a Bionicon C-Guide chainguide - never dropped a chain once, including heavy backcountry trails in the French Alps (and the guide is really quiet too; and v. light. And low price). I never took the ISCG mount off - it's still there, working as an over-engineered BB spacer...
