My first tubeless tires. I have relatively tight tire clearances, so chose these in large part based on reported measurements. I installed them on DT Swiss R460 wheels (18mm internal width) and they measure 27mm after some use.
They went on easily, though seating required a CO2 cartridge on each wheel (I don't have a compressor, but the CO2 worked like a charm). Once on, I deflated, added Stan's sealant, and reinflated with just a floor pump. So far, so good.
I inflated them to 90 psi and went for a first ride. Coming from 23mm 4000SII's (which measured over 26mm mounted), these felt wonderful. At 90 psi under my 200 pound frame, they felt soft and almost bouncy, but at 92 they've felt great. They provide a nice buffer on bad city pavement, but feel like they roll as well as the Continentals. I love the feel of these tires.
Unfortunately, the rear tire has suffered two small punctures that don't want to heal up entirely, both bleed small amounts of sealant between rides. They're fine for three hours on the road still, but it does worry me to see the weeping. I have purchased some of those worm-like plugs, but haven't tried them yet. And maybe I just need to try a different sealant. We'll see.
Since it's early spring, I also ride on a trainer. After the first puncture seemed to have healed, I rode indoors, moved the bike to another room, and head a hissing as the puncture re-opened. A quick spin solved it again temporarily, but that puncture and the other both still weep sealant between rides.
So, love the tires but wonder about their durability. I ride entirely on pavement, some of which is city streets with the inevitable sharp garbage near the curb. If they're going to cost me another $75 every few hundred miles, they,re going into the garbage.
Thank you for your feedback.
