I am getting a power tap sl hub , problem is its 24 spoke and im 195 lbs.

I would love to run a carbon clincher, but i dont want to drop a crap load of money into a training rim. So lets hear some rim suggestons

Right now im thinking

Velocity Deep V
DT swiss 1.2

Deep V then... the 1.2 only comes in 28,32 AFAIK. Kinda wondering what market DT is going after with a 570g rim that you have to put a bunch of spokes in.

Are you hard on wheels? You might be able to go with something lighter, but if it will only be used for training then the Deep V is a good choice.

See post below on exact same subject.

They are going for the largest chunk of the bicycle market. Most high-volume production hubs only come in 28, 32 and 36 holes. DT primarily sells through large distributors, who probably only want a product they can sell through rapidly, rather than have to sit on inventories of rims in less common spoke counts (24 spokes or less).

DT Swiss R1.2 would be a good bet. QBP has them in stock in 24 hole (black or silver) so any shop can get you one.

You could try calling Mike Garcia at Odds and Endos to see what he'd recommend too.

Alex R400 was suggested to me, a good alternative to the Velocity Aerohead. But big riders...deep V, R1.2, or zipps?

The Velocity Fusion is also a good choice. It's plenty strong and weighs a bit less than the Deep V. Make sure to choose a strong spoke for the lower spoke count build.

Anyone have a pic, or build specs for a 24h PT hub? Is 3x impossible due to the size of the flange? Is 2x drive side the only choice?

3x is no problem with the Power Tap hubs and is actually the recommended lacing. Check out (http://www.cycleops.com/pdfManuals/257.pdf) for the specs.

Have you ever looked at a 24H 3x build? The spokes must cross the flange, making it impossible. This is the problem I'm dealing with now, and will have to go to 2x.

Also, with 3x the spoke head angle is tight. Big flanges...problems.

Look at a picture of the Zipp PT wheels, 24h 2x on competitivecyclist.com.

Sorry, overlooked that one. I haven't built with that hub in the 24 spoke version. I've built plenty of large flange Rohloff hubs (100mm) but they only come in a 32 hole option. 3x works fine with more spokes (which is the PT configuration that I had), same as the Mavic build on competitivecyclist.com. Depending on rim selection it may or may not work out. Looks like you're definitely going to need to go 2x on deeper rims. The spokes can cross the flange a bit, but not if they touch the heads of the next spokes. Not sure whether the Fusion rim is shallow enough to allow 3x. You'd have to try it out.

i wish there was a cheap carbon clincher that i could run, but i think im going to go Deep V, im pretty hard on wheels

heres what i train on now, im a 195 lbs
i ride deep Vs, i wish i could get a lighter rim that i could ride everyday and race, but im not dropping 300 for a carbon rim

For high flanges, 2X is more than enough. Even for 28 spokes. More crossings
using tall flanges will also lead to an unfortunate angle toward the rim as they're
most often drilled toward the center of the hub.

If the spokes were to leave the hub at a 45 deg. angle on a 70mm and bigger flange,
you'd still have more than enough torque and wouldn't generate any more wind up
than a standard (44mm) crossed 3 times.

As a bonus, you'll have shorter spokes, greater angle from the rim out to the flange => A stiffer wheel :)
(of course all that wouldn't matter if it's a poor quality rim :( )

Let me just ask the obvious question. Why did you order a 24 hole training hub when you are obviously quite concerned with strenght/durability and are hard on wheels?

My guess is, that had something to do with cost :rolleyes: If I were
to reccomend a rim, the Velocity deep V would b your cheapest
way out here. A Zipp clincher would be cool too ;)

I got it for a very nice cost. All my race rims are 24h rear, but my experience with bontrager race lites was a 24h rim wasnt good. But i think my hand built rim will be a little better

The race lites are some flimsy affair. One shouldn't believe it was
possible to make such a flimsy wheel using so nice components.
That wheel is not representative on how stiff a 24h can be. Many
16h performs better. How much load it can take is another story.
Stiffness, or lack of, of a wheel does not necessarily say anything
about that. On the contrary. Very often they talk loudly about the
extreme lateral stiffness to hide the fact that it's not a very strong set
of wheels. Lateral stiffness ain't the whole story :)

so this shouldnt really be a big issue with a hand built rim, i hope not atleast
