Rim tape width needs to match your rim's internal width, not the tyre size or the rim's outer width, since it is the internal bed the tape has to seal against. As a general guide, add roughly 3-4mm to your rim's internal width to pick the right tape size, so it reaches the bead hooks on either side without bunching up in the middle of the rim bed. This internal width is usually printed on the rim itself or listed in your wheel manufacturer's specs, so measure or check before ordering rather than guessing from your tyre size.

Tape that is too narrow will not reach the tyre bead hooks on both sides of the rim bed, leaving gaps that leak air no matter how much sealant you add, so your tubeless setup simply will not hold pressure. Tape that is too wide bunches up in the centre of the rim bed instead of sitting flat, which can create an uneven surface for the tyre bead and cause slow leaks or an inconsistent seal over time. Getting the width right the first time saves a frustrating cycle of reseating tyres and adding sealant to chase a leak that a correctly sized tape would have avoided.

This tape uses a 75-micron PET film base with a silicone adhesive layer, giving it strong resistance to stretching, tearing, and puncturing while staying thin enough not to add bulk inside the rim bed. It is built with high tensile strength to handle the pressure and heat that come with long road rides, gravel days, and technical mountain trails, so the seal holds up under real riding conditions rather than degrading after a few rides.

Clean the inner rim bed thoroughly first, since dust, oil, or old adhesive residue weakens the seal, then start winding the tape from about 10cm away from the valve hole and pull it moderately taut so it sits flat with no bubbles or wrinkles. Wrap fully around the rim at least once, overlapping past your starting point before cutting the excess, then locate the valve hole by feel, cut a small slit rather than a large hole, and push the valve through before tightening its retaining nut and mounting the tyre.

Yes, the silicone adhesive is designed to peel off cleanly without residue when it is time to replace, so you are not left scraping stubborn glue off a rim you are committing to a new tape width on. If you are converting a wheel that previously ran a different tape or a tube, remove all traces of the old tape and clean the rim bed with isopropyl alcohol before applying the new tape, since leftover adhesive or grime is one of the most common reasons a fresh tubeless setup will not hold air from day one.

Yes, this is a genuine, quality-checked LeBycle rim tape supplied as a 10m roll, enough for multiple wheel setups. Dispatch typically takes up to 3 working days from order confirmation, and total delivery time after that depends on your location and pin code, so we cannot promise an exact day count upfront. All orders are prepaid at checkout since cash on delivery is not offered, and every order carries DoGoodCo's assurance of a genuine, correctly specified part, so simply select the width that matches your rim's internal measurement.
