    My Fantom Pro 29 frame is wearing out where the wheel sits in the frame!

    This is might be hard to understand, but here I go...

    The frame is wearing out big time where the wheel sits in it. The threads on the wheel (the part that sits in the frame) have made the frame much larger than originally. This is on both sides, but more so on the brake side.

    This is causing the wheel to be crooked in the frame. Because of this, the tire rubs on the frame.

    This is absolutely crazy!

    Anyone has this happen?

    I have shimmed the "extra" space on both sides of the frame with an aluminum can that I cut up and wrapped around the threaded piece that goes in the frame. I'm almost 100% positive the little pieces I made will fall out.

    I'm out of ideas, anyone have any?

    Can you post a pic? Have you been making sure the rear wheel skewer is tight before riding each time?

    Are you talking about where the skewers sits in the dropouts? That metal rod that goes through the hub. Is it creating a notch in the dropouts?

    Yes pics will help. Take a couple .of each side.
    There's something about those long grueling climbs that gets my front end all stiff... And I'm not talking about lockout...

    It's not the skewer that is creating the frame to enlarge. Its the part of the wheel assembly that sits in the dropout that is creating the dropouts to enlarge, thus creating the tire to be crooked and rub on the frame.

    It is the insides of the dropouts that are "bad". I have emailed them, just waiting on a response. I'll take some pics...

    I've never heard of anything like that. I know skewers acorns leave teeth indentions on dropouts but never heard of the insides actually wearing down. I.really hope they replace this.for.you. definitely sounds like a.weak.frame. I rode a.Fantom and.loved.it.

    Yeah. The outside of the dropouts have the "teeth" marks on them, which is not a big deal at all. The inside wearing out so bad that the tire rubs the frame is ridiculous.

    Here are some pics...

    This is the brake side...






    Here is the cog side...






    Here is the clearance of left side of the tire and the frame (with the aluminum in there)...




    Here is the right side clearance of the tire and frame (with the aluminum in there)...




    As you can see the wheel is still off a bit as the left side has about 2mm of clearance and the right side has about 8mm.

    It's jacked to say the least.

    EDIT: Fix the pics.

    How old is the frame?

    I'm relatively new to this sport, so I've never seen this before. Did the expansion only happen on the drive side?

    Keep us updated.

    That was very weird about the pics. I have never seen the "random" pics in my life. I used TapaTalk to uplaod them, Maybe some things got crossed in translation.

    They are fixed now.

    I would contact bikesdirect about this and (and please let us know how it goes). I don't see how they could blame this on misuse. Also, on motobecane's site, aluminum frames have a 10 year warranty.
    Motobecane USA | Warranty, but I would try BD first.

    I believe I came across a posting by OP in another thread where motobecane is helping him out, even giving him the option of paying more for titanium.

    confirmed, found it School me on Ti vs. Carbon frames

    OP, did the expansion only happen on the drive side drop out?

    Thank you. Yeah, they offered me an upgrade at a discounted price. Really cool of them.

    It happened on both sides. More so on the left side.

    It's great to hear that BD took care of you.

    After reading all this again, I noticed that the hanger is bent and might have contributed to the dropout widening. Or it could have been a loose skewer. I would say it's a safe guess that being a 250lb rider didn't help the bike either.

    This was caused by not tightening the skewer enough. The axle was rubbing back and forth in the dropouts while you rode. Make sure in the future that you tighten it properly or you could seriously hurt yourself.

    Where'd you end up with this? The other thread got a bit out of hand.

    They offered me a Gravity Aluminum frame as a replacement or a Ti frame at cost.
    I didn't take the Aluminum and at this point I can't afford the Ti frame. So I'm in limbo at this point.

    "the other thread"? What is that about?
