To what extent would you say, that no wheel can compete to Alpinist CLX?
These are newer, wider, faster, (insert marketing claim here). Havenât used them but been super happy with my circa 2015 Aeolus wheels and Iâve heard good things about the RSL37 and the outgoing XXX2/4/6 line so Iâm sure these will be great too

My N=1 experience with Zipp hookless so far has been good. Can get tires on and off without levers which has very rarely been the case with tubed or at least not with Conti GP 4000 or 5000. Had one puncture that hasnât sealed so far, and just stuck a tube in there. So seems best case is reduced chance of punctures as some will hopefully seal and youâve eliminated pinch punctures. Worst case is putting in a tube which is no worse than it would be with a tubed tire apart from the sealant mess. Even the sealant mess isnât as bad as I thought it would be - gives a good photo opp to any friends youâre riding with, but it dries out and peels off easily enough.
Not sure lack of tire choice is really much of an issue. Thereâs enough to choose from, and the ones Iâve tried so far (Pirelli and Schwalbe) seem decent. If hookless sticks around then would expect choice to increase. Guess the issue will be if wheel manufacturers decide hookless isnât the way forward and adopt a different standard instead, in which case tire manufacturers would follow suit and at some point youâre left with wheels you canât buy tires for with no resale value. Hopefully with ETRTO standard updated to include hookless and manufacturers as big as Zipp (=SRAM), Cadex (=Giant) and Enve apparently betting on hookless itâs here to stay. From what I recall, Conti were one of the last big tire makers to release tubeless tires, so maybe not a surprise that they havenât released hookless compatible tires yet.
Sorry to sound like a ludite, but I wonder how much real world advantage they will have over my OLD 404 FC clinchersâŚ
Was solely saying that from the weight perspective. Zipp and Enve currently donât have a wheelset that is at or near the sub 1250g Alpinist CLX. Obviously that in itself doesnât make the Alpinist faster wheels than those offered by the other big brands so I can see where my comment would raise some eyebrows

The Bontrager XXX2 (28mm) was 1300g and the RSL37 (37mm) is 1350. I think thereâs some good weight savings from the hookless design, though potentially some trade offs as well. Not sure why they arenât TLR, my old Roval Traverse SL were hookless and Tubeless compatible.
Alpinist definitely has impressive specs
They are online!
Weight at 1260g, super competitive for a 45mm deep, wide wheel!!!

Apparently 1304g with rim tape and valves
Pretty wild how road wheels keep getting wider and wider. My road wheels are 17.5 internal and from 2015. Now 21-25 seems to be the norm (my first MTB had 21mm internals). Current MTB has 29 internal
Wouldnât surprise me if tires take on the same trend as smartphones and get wider and wider till weâre all riding fat bikes on the road.
Lighter than I was expecting. Have to admit, these are looking great.
Price, not so much.
Those 353 NSW?
Iâve been waiting / enquiring about these since late spring. All outlets said that October was the date when they would be in stock.
Now October has rolled around - the updated position is January next year at the earliest.

Yes. The bike they are supposed to go on has yet to arrive, but I put them on my truck and love them already:
Also, the 42c pathfinders have ballooned to almost 45mm width, crazy.
Nice!
If itâs any consolation theyâre worth the wait!! I was lucky to find some in stock late spring or so and theyâve been great.

Have you gotten some information regarding the use of Pathfinders and hookless?
Both times i have contacted Specialized they have advised against it, but they seem to be sponsoring riders who ride hookless ZIPPâŚ
SoooâŚ
I thought the same thing.
I have made good experience with it on another hookless rim⌠also:
However, as per ETROTO, it is rated for more than 5bar, so not hookless.
I gotta say, that rating is stupid anyway. It is rated to at least 3.3bar, and I would never ride a 42c at such high pressure.

Ahhh, so the rating from ETROTO means that if the tyre is rated for more than 5 bar, then it cannot be hookless ready as well?
That makes zero senseâŚ
Yeah, totally agree, at 42mm 3 bar is max that I would ride. I usually do 2,4 front and 2,7 rear with 40-42mm
Upside down wheels for reduced rolling resistance, brilliant!
