Thanks, this helps.
Usually with tape that is either the same as the ID or a couple mm more, it should work well. With 29mm I’d be worried about getting too much tape up on the lateral portion of the inner rim where it might interfere with tire seating or be prone to peeling or crinkling. The type of tape might make a differerence though too.
With the 25mm Muc-Off tape it lies nice and flat. I’ve used it also with my M525s with have a similar ID.
I recently had LBS tape a wheel and they used Mu-Off tape on Roval Rapide. Watched the guy put on and it looks perfect. Although it has printing, they haven’t had issues with Muc-Off tape (with printing) and Silca sealant, unlike the issue I had with Roval factory tape.
I would like to run the 6.7 as a front wheel on my TT bike. Not super easy to find a fitting tire.
The GP5000TT are among the few super fast tires, that are HL compatible. I fitted the 25s and the 28s. The 28s are officially rated for a 23mm internal TSS wheel, but come out wide af (over 29mm). The 25s come out to just under 27mm, which is perfect in my mind.
Continental does not rate their 25s for anything wider than 21c. That’s per ETRTO 2023.
ENVE however says 25s can be used on these wheels, and even up to 90PSI.
I know the safest route will be going 28s, but I’d like to hear your take here. The 25s are very likely fastest, and since this is for TTing, that’d be pretty high up my priority list.
