Muc OffRim Tape - 21mm

My only gripe is the uncertainty of how much tension to put on the rim tape when you fit it. Despite watching the video etc. it was unclear just how hard you had to pull the tape to get it to stick down. My rims inside are a matte finish so hopefully has adhered okay, as it did lift back up easily when I went to move it.I realised when doing the second wheel that a lot of pressure is required to get a good bubble free finish. Don't worry the tape is bullet proof and won't break under tension so really pull on it. I think it would help if the video had stated this more.I have no qualms about do another bike now, it's easy once you realise what needs doing.

Small note, this was my first time prepping a wheel to run tubeless, bike came with it set up but needed to replace a tire after nearly 18months, so let that help frame my level of experience first. The tape had good adhesion but it wasn't particularly strong, Stan's tape was already on the rim but dirty and a little worn so thought it best to replace the tape before adding sealant etc. The tape adhered to the rim but also came off very quickly and wasn't that flexible laterally as I needed to rework sections to remove air bubbles and have it flush all round. That made it difficult.However, because of it being a very plastic style tape (basically heavier, branded sellotape), when I made a small hole for the valve before feeding the valve through the tape tore and expanded to a larger hole than the valve bung (for context I used a pin to puncture and then the valve stem). This widening meant I had air escaping through the valve hole, but there were also leaks from the spokes around the rim. So I ended up ripping it all of and starting again. Same problem.Third time I decided to go round the rim twice with the tape and it finally managed to seal properly and finally have no air leaks from the wheel itself. So overall, yeah my technique could be called into question, but perhaps this isn't the best variant for an MTB wheel running tubeless. Local Evans bike shop where I went for the valves said in future use gorilla tape, so might give that a go next time!

The tape is quite inflexibe making it quite difficult to lay down without it puckering and getting air trapped under it.I did manage eventually but it took quite some time to keep working out the air and wrinkles.

I run tubeless tyres on a number of bikes and have various versions of this product i.e. different widths. Having set up a pair of eMTB wheels with another brand rim tape I was becoming frustrated with ongoing deflation, even though I was using Stan's sealant. I decided to clean everything up once again and changed to the Muc Off tape. Worked perfectly, again using Stan's. Highly recommended.

Works well tyres have held pressure very well since re-tapping the rim with this. Does the job.

The tape is fairly stiff and had 0% stretch. This means the tape can not possibly confirm to the rim thus leaving many areas susceptible to failure. The adhesive needs to be thicker to aid in sealing. Also if you need to peel it back it can leave residue which, means you will need to take it all off and clean the rim, again. Oh and guess who makes a cleaner specially for removing the residue?The one star is only because I can't give it 0Don't waste your money.

Very good. Would buy again. Easy to use, sticks well.
