I bought a pair of tt 92's and some tubeless rims.
Ive been to three shops trying to get them fitted. One wouldn't try when he saw the groove depth. One gave up after an hour because they didnt want to scratch the rim too badly. The last destroyed rim and a tt92 trying a little to hard to get them on.
It's my opinion that they aren't worth the trouble, at least in this combination of sizes (90/90x10) the groove in the rim isn't really deep enough. Sip should offer them pre fitted. I do notice now that sip Just started offering rim protectors and tire iron kits? perhaps they have been getting a lot of complaints?
If anyone thinks they can have better luck getting them on you are welcome to try. Anybody else have success/failure with them?
