TESA 4289

Anyone used this for tubeless tape? I’ve been reading that tapes with logos on can separate in higher pressure applications as they are 2 ply with a vinyl layer on top for the logo. A few mentions around the place that TESA 4289 (same as Stans??) is the best stuff for  higher pressure.

Any corroboration of this anywhere?

Also if TESA is the stuff to buy, where the he’ll do you get it in the UK? Found some in Lithuania… I need 23mm wide stuff.

I got a big old reel off eBay last time – but it was the 30mm stuff sold in the UK. If you can squeeze the 25mm version in (and it does lens down into the spoke bed, so 25mm will more than fit on a 23mm rim) then I’d go that way.

Yep. The extra width never bothers me i just fit it centrally ish. Then take a scalpel and run it round the rim.

Sorry should have clarified – it’s a 21mm carbon rim hence wanting 23mm tape. I’m a bit scalpel cautious on the carbon…!

Ali is your man

I just got mine off ebay.

You’ll need 2 layers for road wheels with spoke holes so it might be worth getting one tape narrower to go over the holes then the wider tape on top depending on how tight the bead seat is already.

That, and if you don’t already know, get the wheel and tape nice and warm before you start, it makes the adhesive tacky. Leave them on a radiator for a bit before you start. The glue is pressure activated so the tighter you can stretch it on, the better it will stick to the layer below.

You only have to stroke the tape witha scalpel. If you scratch th carbon in anyway you are a cack handed gibbon 😀

So I’ve found some 23mm – how much narrower for the initial layer do you recommend? will 19mm do?

Ha ha – fair enough. Although a straight cut is possibly quite beyond my capabilities!

Always used this. https://www.twistedcogs.shop/product/black-tubeless-tape-25mmx60m

Hmm – I only use a single wide layer – so 25mm internal rim is used with 30mm tape and with an overlap of 15cm or so.  I use wider tyres at 32mm, and only at 55psi, but on a weekly basis, my tyres lose around 15psi.  Do you lose less with 2 layers?

I’d definitely be re-taping those

That black stuff from twisted cogs looks like 4288 which is billed as “medium duty” rather than “heavy duty” in the 4289 description.

4288 has tensile strength of 300N/cm as opposed to 4289 420N/cm. Not sure how much difference if any that makes when used as tubeless tape… The 4289 is thicker too, 144um compared to 114um.

That’s 15psi on nearly 9 hours of riding and 250km. And it’s a decreasing amount over multiple weeks.  After 3 weeks in the summer (1 week riding 2 weeks just in the garage) they’d dropped from 48/51 to 25/25.  I’m not sure I’ve seen much less even with tubes.

My 30mm GP5000s lose about 15-20 psi from 65 over a week. They are factory taped Rovals. Its these I want to re tape to see if that makes a difference. Schwalbe tape is supposed to be good and only needs 1 layer they say. My seller on eBay of 23mm TESA contacted to say it’s out of stock and I can’t find any anywhere else other than 25mm. I CBA to trim it so I’ll try some 25mm MucOff that is due for the skip to see if it fits and then maybe get 25mm TESA and some 19mm as a base layer… If not I’ll try the Schwalbe high pressure stuff….

Don’t use muc off!!! For me it lifted at the join and the sticker they provide was useless. But worse  was removing the residue, what a nightmare.

Yeah – most MucOff stuff is awful. I’ve got some 23mm TESA coming now so I’ll try that double layered with some 19mm.
