These came stock on 2021 Trek Farley 5 from the LBS. I upgraded the tires to studded 45nrth Dillinger 5s and wanted to run them tubeless for the temperamental Canadian winter (-30 C one day, +5 the next).
LBS had a hell of a time getting them to seal up. There's nothing worse that sealant leaking out from the cutouts when it's - 25 C out and you're 10km into the bush.
Annoying that there's very little information from Hayes/Sunringle on the youtube or this web page as how to exactly tape these specific rims for tubeless setup.
I'm going to find the Trek rep from my area and let them know how disappointing the tubeless performance is for these rims. When they work, they work well. But compared to other rims, these apparently are a bugger to tape. The revised cutout pattern is not well thought-out. While they may be lighter than the first generation of Mulefoot, the V2 version does not perform as well from a tubeless reliability point of view. And when it's bone chilling cold out, the last thing any rider wants to be dealing with is a leaky tubeless tire setup!
Now to figure out what to do for next winter...
