Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

The Velocity A23 is a tubeless-ready rim with an inner width of 18mm. It is around 460 grams but is sleeved/pinned. Is there a similar alloy rim that is welded? Requirements:

Tubeless-ready
17.5mm-18mm inner width (this eliminates many of the newer wide rims)
~450 grams
24/28 holes

Pinned rims are just as good. Mavics are welded, and I wouldn't own them.

American Classic ACRD 2218 at 375g fits the bill. 18mm internal, TLR, 24/28h available.

Isn't it true that AC rims can't be bought separately, but rather only as complete wheels. Used to be. Not sure about now. I would be interested if that were no longer true.

They still keep their hottest rims (and other bits) to themselves for their proprietary wheels, but the 2218 is hot as far as low, mid-width, TLR rims go.

Alright, I'll check out these options more closely. I have always used welded rims with great results. I also use higher-end hubs (too bad Alchemy is out of biz) so I try to get "nicer" rims. I had not even thought about American Classic. I'll look at the DT as well. Thanks guys.

Out of curiosity, why spec a max BSW (inner width)?

I'm using either 23 or 25 tubeless tires...no interest in going wider. Anything under 18 (but still 23-24 outside) seems to hold the tire beads a bit more securely due to outward pressure. It isn't a given that the bead will not fall inward if deflated enough but the chances are lower.

Interesting regarding the beads; I didn't associate deflation bead unseating with rim width, but rather vacuum and the mechanical interlock of rim and tire bead. I mean, the carcass seems to have very little shaping force, offering very little resistance to the beads coming together, or the opposite. Probably tread thickness and width determines carcass shape somewhat, though, which of course is variable betwen tires. Maybe the key is tread width in relation to rim bead seat width?

In my experience, with 19.4mm bsw AC Argent and 18mm bsw AC Victory30 rims, speed of deflation is the big factor in bead popping, and slower air release will allow them to stay seated, for a bit, anyway, because setting the wheel down or squeezing the tire at all will cause beads to pop.

Anyway, were it just rim width in relation to tire size, I'd expect the 30c S-One tires to stay "beaded-in" on 18mm internal V30 rims when deflated, but they don't.

I also don't find deflated bead unseating to be a relevant issue to performance or function. In an ideal world, where the beads would be truly locked/in to the extent they could provide run-flat capability, that would be cool, though! As it is now, though, I don't see what difference it makes.

I should add that on those 19.4mm bsw Argents I run 23c Pro One, which plump out enough that fork clearance on the Breezer is absolutely minimal, and hard out-of-saddle sprinting will cause rub on the legs. That's reason to watch inner width, too!

Yes, you make some excellent point, as usual. The bead lock does not seem to be as secure as with mountain bike wheels ad tires, though the beads there are much thicker and the sidewalls much stiffer, so that could be the big difference in the bead-lock. My problem right now is that my NOX rims (20.5 inner width) make it really hard to inflate the tire (Schwalbe Pro One 23) once I deflated them. They are really wide enough (28 external) to be a true cyclocross rim. I'll be able to run 35-38 tubeless tires with them this winter.

So while I did buy two Pro One 25s, I will likely put those NOX rims on the Cross bike and use rims with a 23-25 external width on the Tarmac. I am hopeful that a narrower rim will at least let me inflate the tires with a compressor. Since I am likely going to run 23s on the Tarmac (and 25s on the Roubaix) I figured a narrower rim (though 18 is not really narrow) would give me a better tire profile than a wider rim. From what I have seen, going too wide seems to really square off the narrower tires a little too much. On the MTB, I run 2.3 tubeless tires with an inner rim diameter of 26mm. That seems to be perfect for cornering as well.

So the main issue now is that I simply cannot get the 23 Pro Ones seated. I'll try the 25s this week, and if that doesn't work, I'll have to get narrower rims with (hopefully) a decent bead-to-bead lock. I have been told that TL tires are easier to seat on narrower rims than the Nox's 20.5.

You may be right that the 20.5 bsw on those NOX are giving you troubles, but I've not the experience to speak to it personally. Keep us up to date on your efforts!
