Silly question (I mean… ridiculous but worth a try)

[DYAKOV]

So I’m having the following scenario which is driving me crazy…

Took a rim tape off a spare front wheel and I want to use on a new build. Both rims are the same (hashtagg), both tyres are the same (Monty pro race) in fact I’m even using the same tyre I had on the old wheel, the rim tape was brand new, used for a few rides, so isn’t stretched and overall in a good shape.

I’ve had at least 50 attempts pumping that tyre (planning to invest in a bigger pump too!) and the rim tape keeps moving, so at places you can see the edge through the rim holes. I’ve noticed it stays in place until the tyre has an alright amount of air in (not hard enough to ride) and only moves by the time I’ve fully inflated it.

I don’t really want to super glue the rim tape, also it’s a standard width for a front wheel (not sure if trialtech or tarty own) but I can’t think of ways to keep it in place. Once I manage to position it where it should be I’m planning to pump the wheel and leave it for a day or two so the rim tape moulds around the spoke nipples as well as the rim holes which will then keep it in place but I haven’t gotten that far….

Anybody had the same nightmare before?

Just thought maybe I can use sellotape over the rim tape and stick it to the side walls of the rim (essentially making it a wee bit wider)… I’ll update the thread if it works. Feel like an absolute dummy haha

Is it because when the pressure increases, the tape bulges out into the holes, meaning the edges pull inwards? Proper fix would be wider rim tape, if so.

You absolutely can just replace the rim tape entirely with sellotape. It works absolutely fine as long as you do enough layers, and it can be exactly the width you need it to be.
It's a cozy way of saving 50g for about £1, too (Assuming you did both wheels.)

Granted, the holes in your rims are bigger so you might want an extra couple of layers, but I used to run 5 layers and it was fine running 60psi in a 20" wheel using the old Trialtech Square Hole rims.
Just make sure the layer touching the rim is upside down, otherwise all manner of shit will get stuck to your wheels and undo your precious weight-saving

Cheers dude, already done that on my 20” bike, think I’ll probs go down that route on the 26” as well..

And yeah, the rim tape doesn’t seem too narrow but it isn’t wide enough either. I suppose it’s to do with the profile of the rim, would work much better on a flatter profile…

anyway, thanks for the tip!

Yeah, I've definitely had the same problem before on lightweight rims with large cutouts.  Tape was the only way I could get around it.

Hey there, this is a common problem with Hashtagg rims, both in 20 and 26. It is due to their design with the rim flat profile being in the middle of the sidewalls, something Vincent never thought of when he made them. So using a wider rim tape or making your own is a solution.
