    Tire rub with chain staystay

    Has any one noticed a slight rub inside the chainstay? We have had some muddy trails here and I have noticed some marks inside the chainstay. I am wondering if it's the tire by itself or if it was the mudd collected on the tire rubbing on the inside of the chainstay.

    The bike is a stock 2019 Jeffsy Pro Race 29.

    captain obvious to the rescue here. spin the wheel, if the tire touches or is within a couple mm's, the rub is from the tire itself. if it doesn't, it's from said mud...

    +1 for the response above. The Jeffsy has clearance for at least a 2.4 in the rear, probably even a 2.5. If you’re getting rub on the stock e13 tires then your wheel desperately needs to be trued.

    The wheel seems true.... I have about 1/4 of an inch on the closest side of the chainstay which is where the drive side is and where the rubbing is happening.

    Is it not centered in the triangle?

    If it becomes a problem for you, replace rear tire with a narrower tire.

    Probably collecting mud and.or rocks. OR the tire could be hitting the chain stay during flex (which would be normal).

    This ^^^. The tire, wheel and frame are all flexing when you ride so static clearance you observe when you spin the wheel will get used up and you might get some mild rubbing. Personally I wouldn't worry about it if you've got some protective tape there as shown in the photos you posted. Just replace the tape once in a while.

    I wouldn't change tires [assuming you are running a tire you really like] just to avoid that minor rub.
    Safe riding,

    (edited after inspecting the pics more closely) considering the damage also on the chainstay protector, it definitely looks like your tire is rubbing and likely under sideloading..

    Check your hub to make sure it's tight and you don't have play at the axle.

    I have Invisiframe on the bike. Everything is tightened up and there is no play in the rear wheel. Will keep an eye on it.
