Fitting Continental GP5000TL’s to Prime RR50 wheels

I’ve just had a very difficult time fitting Continental GP5000TL tyres to brand new Prime RR50 wheels. The first bead was difficult to fit but I managed it by hand, just. The second bead was impossible to fit by hand. The problem seemed to be that the first bead fitted sat partially in the well of the rim preventing the second bead going into the well to allow lever free fitting. My wife kindly helped me (she’s a keen cyclist who’s changed loads of tyres herself, so understood the frustration I was feeling) by holding one of the three tyre levers we ended up using. I held a second lever with one hand and used a third lever (a broad, flat Schwalbe plastic lever) to lever the bead over the rim. Each time I managed to lever another few millimetres of bead over the rim my wife advanced the lever she was using up to the Schwalbe lever. I then slid the Schwalbe lever a few millimetres towards the other lever I was holding and repeated the process. This took ages and we both slipped several times before the tyre finally went onto the rim. I tried washing liquid and water, which didn’t seem to help and then GT85, just to help to slide the levers; I was desperate! I broke one tyre lever and managed to chip (it’s very small but I know I’ve done it!) one rim on the inside. I usually just read the posts submitted by others but this is the worst experience we have ever had fitting tyres! I have read posts on particular combinations of rims and tyres and my combination is definitely difficult! I’m now looking for tips to remove the tyres when this finally (in a long long time I hope!) has to happen.

    They are very difficult to fit. Theoretically, they should be easier to remove when the time comes because the bead will have been stretched out slightly by having been mounted to the wheels. I don't think I'll be getting another set. The Hutchinson Fusion 5s I have on other wheels are a lot easier to fit, and give fantastic performance.
  • I think there's a recent discussion thread in the Workshop folder that touches on similar...........😩😤😡

    Try one of those koolstop tyre mate contraptions? I tie to my mini pump and keep in a back pocket. They are good.

    FWIW, and I know it's different as not tubeless, but I can get GP5000 clinchers onto Prime RP50s and Prime Black edition 60mm rims with just fingers & thumbs, and I emphatically do not have a mechanic's hand strength!

    wot Hopkinb said

    rovals + GP5000 = refitting is just with fingers, thumbs and a bit of technique off youtube

    One of the reasons I haven't taken up tubeless tyres is due to the fact of fitting tight rubber onto carbon rims.

    A tip i heard from the TrainerRoad forum was to heat the tyre with a hairdryer, failing that let the LBS sort it.

    That said they are an excellent tyre and i prefer these to my much loved and cherished S works cotton tyres.

    It was an ordeal to get my GP5000 TL's onto my carbon rims but I managed it.
    They have a much larger bead than other tubeless tyres which I think is part of the issue, it's also why they can't be used on hookless rims.

    Not had any issues with either Hutchinson Fusion 5's and Schwalbe Pro Ones on the same rims.

    I have had to remove them since and it was much easier, once they're on the rim they do stretch out a bit.

    Prime wheels and GP5000's are a very tight fit. I found the large 'Fat Spanner' tyre leavers and loads of soapy water did the trick.

    Another reason why I’m not convinced about road tubeless yet. When all rims and tyres are made to a universal standard that means I can get them on and off without swearing lots I might be interested. Until then I’m happy with tubes and roughly two punctures a year...

    With a tyre this tight, in the event you had to put a tube in, it's going to be a pain.

    I contributed to another GP5000 thread over in Road General. I've moved mine to a pair of 15C Ambrosio rims on some handbuilts. They go on by hand. I know they're slightly different to GP5000TL.

    But it's all about the combinations.

    "With a tyre this tight, in the event you had to put a tube in, it's going to be a pain."

    The thing is you shouldn't be putting a tube in, they are "tubeless" use worms to fix punctures that the sealant doesn't seal.

    Key word is "shouldn't", I guess.

  • I actually did give up trying to fit Conti GP5000TL to my alloy tubeless rims. I had no issues getting the hutchinsons or Vittoria Corsa to fit though. There’s no way I’m risking trying to get the Contis over my decent Carbon rims.

    Fitted the 25mm GP5000 to my rear Hunt Aero Disc Light on Sunday, very similar to experience with 23mm on front, gathered slack by hand to fit final ~12" of bead over the rim.
