Who makes lightweight clincher rims in 18 & 24h ?(7 posts)

Who makes lightweight clincher rims in 18 & 24h ?PeterRider

I don't care about aero factor, actually I would prefer non-deep V profiles. Does anybody make (and sell to the general public) such rims ? Plus (ok, I'm being difficult) I want them to be reasonably strong, this is for everyday use, I occasionally go into potholes, jump curbs... I am about 170 lb. If they need occasional truing, this is fine, I know how to do it. If they need truing everyday I'm going to be less happy.

What spokes should I use ? Would 14/15 or Revolution be enough, or would bladed spokes be a big plus ? (If they don't add lots of strength, I prefer avoiding bladed spokes).

Thanks !

For a 170 lb rider, a lightweight, 18 or 24 spoke rim is kind of an impossibility, especially with your stated hitting of potholes and jumping curbs. To get low spoke counts that will carry your weight, you are asking a lot. The other poster's recommendation of Velocity DeepV is a good one, though probably doesn't meet your low weight criteria (ca. 520 gm/rim). With the DeepV 14/15 or even 15/16 would work, if built by a competent builder. I think you've asked for too much.
What about strength in the Rolf wheels ?PeterRider

I've seen many posts about the low-spokes-count Rolf Vector Pros, 240lb riders using them for everything and abusing them without any problem. I had personally one set last year, and did not have any problem when going through potholes (although the little spoke count made me feel uneasy). So where is the strength in those wheels ? Is it due to the fact that they use deep V rims ?

Maybe I should sell this 18h front hub and get a 24 instead :-)

In any case, thanks for the explanations - Velocity fusion and deep V are indeed the two rims I've seen by looking a bit on the web.

Rolf rims are not light. They use a fairly heavy rim to add strength to the wheels, then save that same weight with low spoke counts. But the rim itself is not light. If you are stuck with an 18 hole front hub, why keep it? Is it some super duper fantastic hub that you can't replace? If you are going to use that hub, build it to the strongest rim you can find to make up for the low spoke count. That's the exact same concept that Mavic and Rolf and any other company that builds low spoke count wheels does to make their wheels that strong. They save the weight at the spokes but add it at the rim.

Build your wheel with a Velocity Deep-V. It's the strongest sub 600 gram rim on the market today, and they offer it in those spoke counts that you listed. If your hub is slotted for bladed spokes, use them. They are stronger. If you don't mind spending the money, use Sapim CX-Ray spokes as they are the strongest spokes on the market and the added bonus is that they are also the lightest non-titanium spokes as well. They have a bladed profile, but you don't need to have slotted hubs to fit them.

The hubs I picked...PeterRider

... are zipp carbon, slotted, 18front and 24 rear. Probably an old-style since I didn't find them on the zipp website. I thought I woudl build a light wheelset with them when I manage to scrape funds for this :-) What is the price for CX-ray spokes ? If they are 3$ a pop, not sure I will spend all that money.

I don't care about aero factor, this is why I was initially asking for non-deep-V. Actually, when I was using rolf vector pros, I didn't like at all the sidewind effect that was pushing me to the side.

At 170#, with 18/24 hole hubs, the only rims I would ride are 404s (or something similar).

You CAN find 18/24/28 hole lightweight rims. They're going to be tubular, and once built into a wheel, VERY delicate. Probably not the best thing for you.

You probably want to stick with 32/32 or maybe even 32/36 wheels built 3X if you're going to be hard on them.

Just a note about the potholes and curbs. No road wheel/tire combo is going to be optimal for that kind of riding. The volume of air in the tires just aren't enough to cushion against everything unless you're riding 34-40c cyclocross tires, and they're not light either. When riding in those conditions, be prepared to replace a lot of rims and tires.

I've heard very good things about Sapim CX-ray spokes. My standard is 14/15 butted all the way 'round. I'm tempted to try some 14/17 for my next non-drive rear just to see if the guys on rec.bicycles.tech know something I don't.
