Fitting 28mm Road Tyres with Rim Brakes

Hi All,

Has anyone fitted 28mm road tyres to their road bike? I have an Orro Gold currently with 25mm tyres and want to fit some wider tyres for a bit more stability and grip etc. but I am worried if they will fit past Ultegra rim brakes. Any advice would be appreciated :)

    Currently have 28s on my Moda using 105 rim brakes and still have a set of longboard mudguards fitted. Couldn't fit anything bigger though. As long as you have clearance you should be ok, remember that you have to release the little lever on the brake to give extra space to remove wheels.
    Too many bikes according to Mrs O.

    will 28mm tyres fit without rubbing the frame?
    ultegra standard calipers are rated to 25mm I believe but just about ok with 28mm depending on the brand / model of tyre. and the rim combination. they may be a squeeze to get the wheel in or out with the tyre inflated.

    The latest versions might be better, certainly the dual mount calipers are designed for much wider tyres

    I have GP4000’s in a 28 on my CAAD12, it’s tight but they just about fit.

    Brake calipers need loosening off fully when removing & reinstalling the wheel though.

    I tried to fit 28s to my old Trek 2.3 and whilst they were fine with the brakes and width, they were way too tall.
    You can fool some of the people all of the time. Concentrate on those people.

    those GP4000's come up very wide not suprised its tight. nice bike btw!

    Cheers.

    I was expecting them to be wide as I knew they come up large but I wasn’t expecting them to be that tight if I’m honest.

    When they need replacing I’ll probably go back to 25’s as it’s faff messing about with the brakes every time the wheels need to come off.

    I realise this isn’t completely relevant to your issue but I have Durano 28s on my Px Maratona with SRAM Force brakes.
    There is plenty of room in the frame and the brakes are ok with the blocks at the bottom of the slots.

    An easy way of finding out how much clearance you have is to run a hex key around the tyre at each point it comes close to the frame/brake. The size of the hex key tells you the clearance. You will want 3-4mm clearance at least with the new tyres, so I'd be looking for 5-6mm clearance with the current tyres.

    I've fitted 28mm Hutchinson Sector to my Orro Gold - the wheels have Kinlin rims. The tyres fit fine - done a few hundred miles now and no hint of rubbing.
    Never be tempted to race against a Barclays Cycle Hire bike. If you do, there are only two outcomes. Of these, by far the better is that you now have the scalp of a Boris Bike.

    I found that these method for removing/installing wheels with 28mm tyres to a bike with correctly adjusted rim brakes was to do so with air out of the tyres. Pump up once on.
    Using the usual brake opening methods was insufficient when inflated.

    Edit - For clarification, TRP RG957 & Durano 28s on Ambrossio or Campagnolo rims.
    The above may be fact, or fiction, I may be serious, I may be jesting.
    I am not sure. You have no chance.

    That isn't the case with my SRAM Force brakes with Schwalbe Durano 28 tyres on Archetype rims. The brake blocks just touch the sides of the tyres so the wheel can easily be removed and refitted when fully inflatated.

    Thanks :) I'm running 25s at the moment and there is about 5-6mm clearance at the closest part.

    Thanks, there is about 5-6mm clearance currently.

    Thanks for the advice chaps, the clearance is pretty close at the moment, especially at the narrowest parts as shown on the photos, it's about 6mm. I don't want to have too little clearance that debris could get stuck.

    I realise you're asking about rim brakes, but just to say for interest that bigger tyres, stability, grip etc, as you mention, is why I moved over to discs from rims. For me as a bigger rider too, it's been a fantastic move.
