We seal wire-spoke rims with aerospace-grade tape and a proper tubeless valve, then hold them at 3 bar for 24 hours. No tubes, no sudden deflation, no compromise on the classic look.

The problem
A pinched tube fails instantly at speed. It builds heat on long descents. And it forces you to carry levers, patches and a pump you'll probably never want to use in the rain.
A puncture deflates slowly and predictably, so you roll to a stop instead of fighting the bars.
Ream it, plug it, inflate it. No wheel off, no levers, no wrestling a hot tyre in a gravel lay-by.
Less internal friction means lower tyre temperatures on long, loaded motorway days.
Drops to 18–20 psi off-road without pinching a tube. More grip, more comfort, fewer dings.
Dropping two tubes shaves up to 1.2 kg of unsprung mass. Steering and suspension both notice.
Spokes stay visible and serviceable. We seal the rim bed, not the spokes — nothing gets hidden behind a cover.
The process
Drop the bike off before 10am and ride away the same afternoon — or leave the wheels with us and we'll call you when they're proven airtight.
Tyre off, rim bed cleaned, every spoke checked for tension and corrosion. Cracked nipples get replaced before anything is sealed.
Solvent wipe, then forced air. Tape only sticks to a bone-dry, oil-free surface — this is where most DIY jobs fail.
Two overlapping wraps of 3M sealing tape, a punched valve hole, and a rubber-grommet tubeless valve torqued to spec.
Inflated to 3 bar and left overnight with a logged gauge. If it loses even 0.1 bar, it gets stripped and redone.
We put the wheel on the truing stand, measure lateral and radial runout, and correct it before sealing. You get a printed readout with your invoice — plus a photo of the sealed rim bed for your records.
Straight talk
No hype. Here's what actually changes on the road and in the workshop.
| Scenario | With a tube | CloudPedia Tube |
|---|---|---|
| Puncture at speed | Sudden deflation | Slow, controllable leak |
| Roadside repair | Wheel out, levers, patches | Plug kit, ~4 minutes |
| Heat build-up | High, especially loaded | Noticeably lower |
| Unsprung weight | Heavier | Up to 1.2 kg lighter |
| Off-road pressures | Limited by pinch risk | Down to 18–20 psi |
| Spoke adjustment | Simple | Needs a re-seal — first one free |
Sealing is not recommended for heavily corroded, cracked or out-of-round rims. We'll tell you honestly before taking your money.

Reviews
"Ran the Ténéré across the Pyrenees on 19 psi with no tube pinch the whole trip. Picked up a nail near Jaca, plugged it in four minutes and carried on. Genuinely changed how I ride."
"I'd tried the tape thing myself twice and it leaked both times. These guys pressure-tested overnight and handed me a printout. Ten months on, still holding exactly 2.4 bar."
"They called to say my rear rim was out of round and that they wouldn't seal it until it was trued. Cost me an extra forty minutes and probably saved me a bad day at 70 mph."
Questions
No. The tape sits over the rim bed, not over the nipples, so you can still true the wheel. If you do break the seal while adjusting a spoke, bring it back and the first re-seal is free on any Pair or Adventure booking.
Most cast, forged and welded alloy rims do. We inspect for cracks, deep corrosion and out-of-round running before we start. If a rim won't seal safely, we stop and refund the labour — you'll never get a wheel back that we wouldn't ride on ourselves.
Yes — fit a tyre marked tubeless. Tube-type tyres have a different bead and won't seat reliably. We stock and fit common adventure sizes and can order anything else with a week's notice.
About 90 minutes of hands-on work per pair, but the 24-hour pressure test is what sets the collection time. Drop off before 10am and you'll usually ride away the same afternoon. Leave the wheels only and it's next-day pickup.
Twelve months against air loss caused by our sealing work — the tape lifting, a valve leaking, a bead-seal failure. Punctures, kerb damage and crash damage aren't covered, but we'll always repair them at cost.
Tubeless-ready bicycle rims, yes. Classic steel rims with a hooked profile are usually a no — the bead seat simply isn't designed for it. Send us a photo of the rim and we'll give you a straight answer before you travel.
