    Can't Get Rid of Play in RF Next Cranks

    I've got about one season on a pair of RF Next carbon cranks. They've been rock solid other than that stupid preload ring that I replaced with a beefier Cane Creek version.

    I noticed some wiggle in the non drive side arm so I took it all apart, cleaned it, re-greased it and reinstalled it and there is still a little wiggle in the non drive arm. I know the installation process is right and I know the drive side arm requires a lot of torque so its on there as tight as I can reasonably get it.

    I'm hoping for some insight on getting these cranks wiggle free.

    Sounds like play in the bearing

    Make sure the spindle interface of the crank arm isn't disbonding.
    Has happened to many, including me.
    Well known next sl problem, disbonding pedal insert of the crank arm as well...

    can you tighten up the pre loader?
    Looking for a Medium Scott Scale frame, preferably a 2012 in 26.

    this was my first thought.

    I don't want carbon cranks...but if I ever did, they wouldn't be Race Face. The Turbine CINCH cranks are pretty solid, though.

    Funny thing, I have just discovered my 2nd next sl is done. Didn't last a year. Just like the 1st one. And I am only 140lbs...

    Damn. So you're on your second pair? What keeps failing?

    You'd think these cranks would be more durable at the price they're charging. Might be time to go back to good ol' alloy Turbine cranks.

    This would be my guess too. Happened to my replacement after the first had a loose pedal insert.
    Second one had the crank insert get loose.
    3rd one is ok so far. Crossed fingers

    Do you know if there is a new warranty applied to the replacements?

    No, I don't believe so. I had 2 sets of Next SLs and I lost track of how many times they were replaced. At one time they replaced with G4s which were no better. The last time they replaced with Next Rs which have been holding up fine since winter.
    I got some bad ideas in my head.

    Hard to find any solid info about the warranty on their website. Is it 3 years for next sl? Non g4.

    I believe the G4 are finally being replaced by a new model. Asked my frame builder to get a price for some and was told that QBP has them clearanced/discontinued. Maybe G5 coming?

    I thought when they first came out they were longer warranty than 3 years, but I think it was removed from the website as I can't find anything about it anymore.
    Frustrating for sure.

    Well upon closer inspection, it is the spindle that has developed play where it connects to the non drive crank. I got these from a shop 2 states away over a year ago and have zero receipt so it looks like I知 S.O.L.

    I知 frankly kinda pissed. I致e been religiously using Race Face parts for over 20 years and when I invest in their high end cranks they fail after a season and I知 a stuck with them. Absolute crap product.

    I had one like that and it was only loose, tightening the crank to the spindle (non-drive) solved it.

    Yeah I tried that after watching a video on how to remove the spindle. At least I was able to narrow down the issue to the left arm. I値l call RF and see if they can send me just a left arm.

    Time to cannibalize another bike to get some functioning cranks. P.I.A.

    So I contact RF and they said I'm basically S.O.L. because I don't have a receipt. That's their policy, it is what it is. I'm hoping a shop can order me just a replacement left arm.

    Worst case, I was thinking of using epoxy to permanently bond the left arm to the spindle. I'll never have a reason to remove the left arm. Anyone see this as a terrible idea?

    An epoxy that is actually strong enough and doesn't crack due to the loads imposed on cranks/spindles? I doubt it'll work in the long term.

    Yeah I am rethinking the epoxy idea. I may try a Loctite type material that is meant for press fit bearings to see if that cures it. Otherwise, RF confirmed that I can order just a left arm from my local shop. Not ideal, but at least I'll get them going again. I'm dreading what RF will charge me for one arm.

    They ask you to cut them when they are replaced for warranty. My first set had to be sent back.
