At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The KranX Tubeless Rim Tape is a really nice product, feeling both sturdy yet pliable and fitting well to the rim, creating a good seal – and all at a very good price. It compares really well with more expensive options from the big brands, and will be at home even on the best road bike wheels and best gravel bike wheels you can get.

After replacing my old tape with a layer of KranX Tubeless Rim Tape, I was able to inflate my tubeless tyres effortlessly without even adding any sealant. Even after a week of being left inflated this way, there had still been no leaking through the rim tape.

I never thought I would be able to say I had an enjoyable time while applying new tubeless rim tape, but I did. It's stickier than a lot of cheap tapes for a start, while still being pliable enough to fit well to the contours of a rim.

It's also tough, so pulling it tight to ensure an air-tight seal caused no undue stress or tearing. Despite this it's easy to put a hole in for the valve (I just used a small hex key to poke one), so that doesn't cause any grief either. Repeatedly changing tyres hasn't shifted it at all, either, and no gaps have appeared during the test. It basically looks as it did when first installed.

The KranX tape comes in lots of widths – 19mm, 21mm, 23mm, 25mm, 27mm, 29mm, 32mm and 35mm – so it's easy to get the perfect size for your specific wheelset. In my case, with an 18mm internal diameter to fill, the 21mm tape fits perfectly and leaves no gaps either side.

I found you only need one layer on each wheel, and with this being a 10m roll there's enough to wrap three wheels. Tell your tricyclist friends…

At £9.50 per roll it's only a few pounds more than some far less user-friendly 'budget' options. It's also cheaper than the both the Muc-Off Tubeless Rim Tape – up a quid to £15.99 since Stu tested it in 2020 – and the Schwalbe Tubeless Rim Tape that Dave tested the year before (still £20.99), despite being comparable on performance.

Overall, I reckon this tape is great, and the price is attractive too. I would happily recommend it to anyone.

Verdict

High-performing rim tape at a great price

It's not bad value compared to other brands but a roll of Tesa 4289 tape is still cheaper as it doesn't have 'cycling tax' added to the price and is the best tubeless tape I've ever used.

Sounds like a great product. Alas, can't find a supplier for the narrower widths! So looks like it's Stans again, @ £20 per...

Katche - do you definitely *need* tape that wide? My understanding is it's only necessary to cover the central groove + a bit either side to airproof the spoke holes? Also, for such wide rims, you could try Gorilla tape. I've a huge roll that only cost a few £s. I've not tried to tape any rims with it (I'm all tubeless these days but my widest rim is about 27mm internal) but it's proven possible to tape some complicated shapes. It's flexible too, & super sticky, I've even managed to patch a big hole in a down jacket with it & so far, touch wood, it's working a treat.

One of my wheels had been done with multiple layers of electrical tape, and it seemed to work. But I'd be more confident with a single layer of the "correct" stuff.

Having a look online the only other ones available at 45mm are Orange seal and Jobsworth. The Jobsworth blue looks like the stuff that was double wrapped onto the other wheel, but seems difficult to source. The Orange Seal stuff looks good, but pricey. Has anyone used it, at any width? Is the extra expense worth it? I like their endurance seal, it was in the bike when set up for me and I have continued to use it.

Yes you do need tape that wide because high pressure air will go under an exposed edge of tape and find a way out. You want the impermeable surface of the tape to cover the rim bed and go under the bead of the tyre, so that the bead sits on the tape. 

Gorilla tape will work to begin with however it becomes a horrible sticky mess some months down the line. Only use it as a last resort. Electrical tape I would say do not use at all because it lacks mechanical strength and will give way under air pressure. It might be ok on Ktache's fat bike rim because the required air pressure is so low but for higher pressures, do not use.

Please. Less Fat, more Plus...

But you are right on the less pressure, 10 to 11 on the front, 14 or 15 on the rear, max.

That is a lovely bit of taping there. The way it forms into the well of the rim.

I'm using WTB, and it really is not fun, there is no pliability so getting it to form to the bottom of the well without creasing is a nightmare.  I need 45mm to fit my 50mm rims so not much choice.

Any suggestions?

Tesa 4289, a tape made for packaging, is "very similar" to the branded yellow tubeless tape. It comes in long rolls (66m?) and is quite cheap.

Quick googling hasn't turned up any in 45mm , only 50mm, but when I bought a roll from a tape supplier (Viking maybe, I can't remember) they told me that it was made to order by cutting a slice off a much wider "log" of material. 

So it might be worth calling a supplier and asking if they can cut a 45mm slice specially for you. I imagine one roll would be more or less a lifetime's supply...

It's not too difficult to cut your own slice if, eg, trimming 50mm tape (seriously?!) to 45mm. Put tape roll on a nice flat surface. Support a sharp craft knife such that the blade is 5mm off the surface. Hold the knife firmly in that position and with the other hand, carefully turn the roll against the knife. You'll soon be trimming into the roll and will be able to peel off a 45mm width to seal your fat bike (I assume) rim.

Would 42mm suffice do you think?

I really like the black DTSwiss stuff for road wheels. I've only used the twenty-something mm stuff, but it does come in up to 42mm apparently.

Like all things tubeless, it benefits from being warmed up before application. I tend to pop it in a low oven, whilst blasting the rim bed with the wife's hairdryer.

Then the tape is super tacky and complies with the rim bed beautifully.
