Going tubeless is one of the best upgrades you can make to any road, gravel or mountain bike. Lower rolling resistance, better grip, self-sealing puncture protection and the ability to run significantly lower pressures all combine to transform the riding experience. Here are the best tubeless conversion kits available in the UK.
Top Picks
Stan’s NoTubes Road Tubeless Kit
Stan’s NoTubes invented modern tubeless sealant and their conversion kits remain the benchmark. The road kit includes two valves, rim tape for two wheels, two bags of sealant and all the tools you need. The rim tape is notoriously reliable at holding an airtight seal and the sealant formula provides excellent puncture protection for UK road conditions.

Orange Seal Tubeless Conversion Kit
Orange Seal has earned an excellent reputation among mountain bikers and gravel riders for its fast-sealing formula. The conversion kit includes endurance-formula sealant that stays active in the tyre longer than many competitors — an important consideration for UK winters where temperatures accelerate sealant drying. Excellent puncture sealing speed and coverage.

Effetto Mariposa Caffelatex Tubeless Kit
Caffelatex is a foam-based tubeless sealant from Italian brand Effetto Mariposa that creates an unusually robust sealing layer inside the tyre. The tubeless conversion kit includes everything you need and the sealant is known for sealing larger cuts than liquid-only alternatives. A premium choice for riders who tackle rough roads or technical trails.
Muc-Off Tubeless Puncture Plugs
While not a full conversion kit, the Muc-Off puncture plug system is an essential companion to any tubeless setup. When sealant alone fails to seal a larger cut, these mushroom-shaped plugs seal the wound from inside the tyre without requiring tyre removal. A small but genuinely important tool that has saved many a ride.

Gorilla Tape Rim Tape for Tubeless
Many mechanics use Gorilla Tape as a cost-effective rim tape solution for tubeless conversions. Applied carefully in two overlapping layers it creates an airtight seal on most rims at a fraction of the cost of purpose-made rim tape. An excellent option for budget-conscious conversions, particularly for mountain bike wheels with wider rim beds.

Buying Guide
Check that your rims are tubeless-ready before attempting a conversion. Rims without a hooked bead or rated for tubeless use may not seal safely.
Use proper rim tape, not inner tube strips. The correct tape adhesion and thickness is critical for maintaining an airtight seal under riding pressure and impacts.
Sealant volume matters. Road tyres typically need 30 to 60ml per tyre, while 29er mountain bike tyres may need 90 to 120ml. Always err on the generous side.
A good tubeless floor pump or compressor makes seating the initial bead much easier. Many tubeless tyres will not seat with a standard pump — a blast of high volume air is needed.
Plan to top up sealant every three to six months depending on climate and tyre usage. UK cold and wet conditions dry sealant faster than summer conditions.

Final Thoughts
Tubeless conversion is the single best upgrade most riders can make to their existing wheels. Start with Stan’s if you want the proven system, or go with Orange Seal for superior sealing speed. Either way, you will not want to go back to tubes.
Buying Guide
A tubeless conversion kit contains everything needed to convert a compatible clincher wheel from using an inner tube to a sealed tubeless system: rim tape, valves, tyre sealant and sometimes installation tools. Running tubeless eliminates the most common cause of punctures — pinch flats — and allows lower tyre pressures for better grip and comfort on UK roads and trails without the penalty of increased puncture risk.
| Factor | What to Look For |
|---|---|
| Rim Tape Quality | The tape must seal the spoke nipple holes completely and adhere firmly to the rim bed under the pressure of 50 to 90 psi (road) or 25 to 40 psi (MTB). Look for tape with correct width for your rim internal width — typically 21mm to 25mm for road and 27mm to 33mm for MTB. Poor-quality tape that lifts at the edges allows air to escape past the spoke holes, causing persistent slow leaks that are frustrating to diagnose. |
| Valve Design and Sealing | Tubeless valves must seal perfectly where they pass through the rim tape, as this joint is a primary leak point. Aluminium valves with a rubber base gasket and a locking nut are the most reliable. Valve cores should be removable (using a standard valve core tool) to allow sealant injection without removing the tyre. Valve length must suit your rim depth — 44mm valves work for most rims up to 35mm deep; deep aero rims need 60mm or longer. |
| Sealant Volume and Formulation | Most conversion kits include 60 to 100ml of sealant — sufficient for an initial charge but not for multiple tyres. Road tyres require 30 to 60ml per tyre; MTB tyres require 60 to 90ml. Latex-based sealants (Stan’s NoTubes, Orange Seal) seal punctures up to 4mm quickly but dry out over three to four months and require topping up. Fibre-reinforced sealants seal larger punctures and last longer between top-ups, which is advantageous for UK tour riders. |
| Compatibility Scope | The best kits explicitly state compatibility with tubeless-ready (TLR) rims and tyres. Some kits can convert non-TLR rims using double-layer tape, though success varies. Confirm the valves match your rim hole diameter — most modern rims use a 6.4mm hole, but some brands use 8mm. Providing valve-hole grommets in multiple sizes is a useful kit feature that covers a wider range of wheels. |
| Kit Completeness | A full conversion kit should include tape, valves, sealant, a valve core removal tool and installation instructions. Kits that include a sealant injector syringe simplify refilling without removing the tyre. Stan’s NoTubes Tubeless Kit and Muc-Off Tubeless Kit are comprehensive market leaders; budget options from Peaty’s and WTB cover the essentials for riders on tighter budgets. |
