Can You Build Your Own TT Wheels?(7 posts)

Can You Build Your Own TT Wheels?Roundabout
Sep 29, 2003 7:33 AM
Any component suggestions for building my own TT wheels? The price of the fast HED and Zipp wheels is too high. Could I do almost as well building them myself for less cost? Is it worth it?

Building a disk is probably out of the question, but an aero rim/bladed spoke wheelset is doable. I have built regular road wheels.

Suggestions on rims/spokes/hubs/sources/prices? For reference, I am about 185 lbs and tend to be a gear masher. Anyone else done this?

you can find those cloth spoke fairings for like 60 bucks a wheel and clip to your existing wheels.

Heck yes you can build your own TT wheels!

I've had good luck with Velocity Deep Vs with American Classic cassette hubs. I'm about the same weight and build them 24/24. If you're concerned about the strength, go 24/28. Stick with 14/15db spokes, and cross the rear at least twice on both sides.

I've also found some 404 rims for "inexpensive" on ebay and other places. I built a track 404 wheelset with Suntour hubs and haven't had a problem with the wheels in the 18mos that I've been racing them. I found a pair of 18/24 Hugi hubs somewhere that I traded off to a friend of mine for some stuff. He had them built into 404s for the road and saved a few hundred $$ over the stock wheels.

When CXP30 rims first came out, I built several pair of them up into pretty fast wheels. Similar to the Deep Vs, but probably a little heavier.

Depending on what you're doing with the wheels, I'd recommend a pair of Shamals or the original Cosmics. IIRC, the Cosmics were one of the fastest spoked wheels ever tested in a wind tunnel. They're heavy, so accelerate a little slower, but for TTs, they're great. You can find them for $2-300 on ebay right now. Stick with the 16/16 wheels for aero. The later ones with more spokes aren't the same wheels.

That help?

Used is a good idea but I prefer to build. A fairing works but only on the back wheel. The Zipp 404 rims are too pricey (but deep and very nice). The Velocity Deep Vs sound like a good choice, moderately deep and moderately priced.

Why do you recommend round spokes? and why cross the spokes on both sides in the back and not just the drive side? Did you radially lace the front?

I see that the Velocity rim is 30 mm deep. Are there any deeper reasonably priced rims out there?

Does anyone know of any hubs that work with straight-pull spokes? or hubs that put the spoke nipple at the hub?

Thanks for the suggestions. Please keep them coming.

You can buy the Zipp rims by themselves. Finding hubs in low spoke counts can be problematic but white industries and a few others make them. Round spokes are okay - but you can try sapim bladed spokes just as easily.

Note: if you go the Zipp rim route stick to radial or 1x lacing. They warn that the carbon rims aren't stressed for much of an angle at the nipple/rim interface.

A deep section rim with 24 bladed spokes (Wheelsmith AE, Sapim CX ray) should give you almost all the same benefits as any other aero wheel. On the front you can lace radial or 1 cross with all the spokes head out, to reduce the profile even further.
Don't worry about the spokes- the deep rim makes up for thier low count / thickness. I built a 24 spoke wheel with 24 AE15's and its VERY strong. I weigh 185 lbs and I would confidently use this wheel for cyclocross. My wheel is a bit unusual in that it usese 36 hole hub and rim, leaving 12 holes empty, producing a "paired spoke" effect. I'm not sure its truely more aero (the tape over the empty holes can't help), but its not hurting any.

For the rear, you could maybe borrow an old HPV trick. Reportedly, mylar packing tape apparently shrinks some when you hit it with a blowdryer. Why not just build a normal wheel with an aero rim, then cover everthing from the brake track to the hub with neat, snug tape, then tighten it all up with the blowdryer?
