|I need a cheap pair of aero wheels since I will be competing in 6 time trials next season. I have been considering the Velocity Spartacus from chucksbikes.com. Any other alternatives? Weight is not much of a concern since most TT's are flat.|
|Keep an eye on ebay for these||spookyload|

|Specialized Trispokes, aerospokes, and rev x wheelsets. Most can be had for under $300 on ebay when they are listed. The aerospokes in particular go relatively cheap and are very aero wheels.|

|... and depending on the course profile, could be more of a hinderance...
I'm unsure of your abilities and/or need for aero hoops... which to a degree, the benefits of said are dependent on your sustained speeds during the race.
Be the bike.

|true, I also agree with he sustained speed during the race. Most are flat 20k TT. I'm sure I can average 24-26 mph, so I'll be on the lower end of the benefits of the wheels. To be honest, it's more of a "want" than a need.|

As has been pointed out here several times, aero wheel will save you more time the slower you go.

|Well, sort of. If you have great aero wheels at 10 mph, you'll cover 20 miles about 64 seconds faster than with conventional wheels. At 20 mph, you'll "only" be 57 seconds faster with the great aero wheels. Of course it would take you 2 hours to gain those 64 seconds at 10 mph. You can call that saving "more" time if you like, but the speed differential at 10 mph is only 0.09 mph, compared to 0.32 mph at 20 mph. You're only saving more time because you're going so slow. It's a specious point.|

|I would hardly call it specious. The original poster said he was interested in improving his TT performance. He also said he felt his speed put him on the lower end of neeeding aero wheels.
Most riders look at the results of a TT and say something like "If I only went X sec faster, I could have moved up Y places." So, the point is that if the OP is slower (and I'm not saying that) rather than not needing aero wheels, he will benefit more from them. To use your example, if a rider's capability is to TT at 10 mph, he can look at the results and project a finish time 64 seconds faster than he rode. If his ability puts him at 20 mph, he would look 57 seconds up the results.
There are many things we can do to improve performance, but if someone is training as hard and as smart as possible, then his physical limits are what they are, I see nothing wrong with pointing out that aero wheels are still a benefit even for a less gifted rider.

|I have the Spartacus wheelset and even though they are 30mm rims they don't really offer too much in terms of aerodynamics compared to the Specialized Tri-spokes.
Like someone else suggested, I bought my Tri-spokes off ebay for a really good price. They are tubulars and they aren't that heavy especially for a TT. But the aero advantage they provide is huge. I did a 28 mile course (West St. Louis County) with several decent hills to compare the wheels. I rode both at the same heart rate and same weather conditions during the same week. The Specialized wheels were 2 min and 1 sec faster than the Spartacus wheels. You can see that the added weight of the tri-spokes was not even a factor even though I had three hills to climb. (Ossenfort, Melrose and Hardt for those familiar with the area)
For a TT, true aero wheels need to be at least 51mm deep and aero always matters more than weight. Zipp 404 or 440's are also a good choice since they have 58mm rims. The Hed Alps is another option with their 51mm rims- they are basically Hed H3 rims with conventional spokes. But the best bang for the buck will be Specialized wheels on ebay. You can get them for a little more than the Velocity wheels.
|How much of an aero advantage are Rev-x's? Ebay=Cheap||Swat Dawg|

|What about a set of Spinergy Rev-x's from ebay. I see them all the time on Ebay, and they are always cheap. They look like they should be very aerodynamic. I know they are illegal for UCI races, but how many of are UCI-ers. Not I!!! Does anybody have the specific numbers for as set of these as compared to Zipps and the tri-spokes.|

|I know they are not as aero as the tri-spokes I don't have the actual data on hand but I've seen it on different sites.
Personally I am leary of the Spinergy's. I've never seen or heard anyone that had anything bad to say about them. However, that web site which lists the sudden failures has really turned me off of the Spinergy wheels. You have to make your own decision on whether there is a real defect or not. Based upon what I've read I choose not to use them.
|Here is a link showing some generic data versus tri spoke||spookyload|

|It also shows data compared to 32 spoke wheels. http://www.nimble.net/ click on the technology link to the left.|

|So, how come I don't see more of them? They are surprisingly light, roughly the same price as Zipps or Reynolds, but more aerodynamic. Are they legal for crits and road races? It seems like they would be good to use at least as a front wheel, and being so strong maybe a cyclocross wheelset. They would shed mud incredibly well. So where is the chink in the armor? Is something I'm not seeing or that they're not saying? I mean manufacturers would'nt tell us only the best things about their products would they, and leave out the down side. Would they? ;-)
But really what is the other side of these wheels?

|Most people don't plunk down $1500 for a set of wheels. The other reason is name. How many people do you see riding Lew wheels or any Nimble product. They don't advertise on Performance or Nashbar, so most people have never heard of them. You don't see many people riding American Classic wheels either, again because of lack of mass marketing.|

|Nimble has some deal where they won't sell through LBS. From what I understand this really ticks the LBS off so they in turn put down the Nimble products since they don't sell them.|

|When you're browsing ebay, keep your eyes open for a set of first gen Cosmics (16/16) or Shamals. Very aero, not too expensive. I bought a pair of almost brand Cosmics new for about $250 last year. I've seen them going for less now.
If you're racing TTs, you may also want to think about a disc. They're much faster than any of the spoked wheels. The one I want is the Accel 2. 675g for a disc wheel... Mmmmmm, liiiiggggghhhhhtttt. The older HED discs don't go for that much $$ sometimes.
|Thanks to everyone||Fender|
Dec 21, 2003 6:27 PM
|While I have not made a decision yet, I am looking into specialized tri-spokes, spinergy's and shamals (really like them). My first TT is not until March 7th, so I have a while before I really get anxious (and pay full retail on ebay for a used product j/k). I am keeping an eye out.
thanks! Happy Holidaze to all!
