I should have been more specific.

I want to train on these wheels - non competitive. I want to know how they might be suited / inappropropriate to use in a regular road bike frame on flatter terrain.


i have a Corima 3 spoke on the front for racing TT's and they are a nice wheel and strong enough train on; however i don't think there is a clincher version available and unless you have heaps of $ would you really want to train on tubulars?


I've heard good things about the Corima 3 spoke wheel

How much would one set me back ?

Corima Aust is offering fronts for $990 and Campag/Shim/Sram rears for $1100

I can't find any counter intuitive info as to why not for a road bike....

<froths at the mouth>

What's the difference between 3 spoke and 4 spoke, performance wise?

Online chatter - if you take it at face value, says the 3 spoke is an aero improvement on the 4 spoke wheel and cuts the air quieter with a better flowing profile spoke shape (said 'tear' shape)

I want to shout myself a pair of carbon wheels to run on my C50 for flatter terrain. I'll take any aero benefits I can get when I get moving fast enough to make it work but I freely admit I just love the look of these......... and I can't afford 1/3 rd more $ for MadFiber......

Hey everyone
sorry to butt in, but has anyone heard of 'shock' carbon wheels? http://www.shockcarbon.com.au/carbon-wheels.html

im looking to buy my first set of TT wheels and just wanting to get opinions.. (i have been looking at the 88mm)

they are based in Australia and look suspiciously cheap..

Thanks!

Nice wheels! They are Chinese made rims and I wouldn't be suspicious regarding the price. If you do a search on Aliexpress, you'll find dozens of suppliers with similar wheels for around the same $ or less.

1080 would be a handful in wind... I get a bit nervous with a 80 mm when on the extenders if trucks and that are passing. So fast wheel but not usable every day.
On the tri-spoke ... Can you use them in TTT's as I know you do some Mike.

The 2011 NSW TTT was so windy that I was the only team member who used the clip-ons on the return leg. Definently not 1080 conditions.

Sorry TLL, I'm not understanding your tri-spoke comment

Here we're not allowed to use three or four spoke wheels in team time trials. Only in solo time trials can we use them. I am not sure if that is a standard regulation worldwide or not.

Unless you do TTs on perfectly flat courses I think the weight penalty of 1080 would make it not viable. An 808 might be a better compromise. I run a 404 on the front of my TT bike, mainly because the courses I ride usually involve hills of some sort.

AFAIK you are allowed to run 3 or 4 spoke wheels in a TT here in Australia. There is at least one guy in my club that runs a tri-spoke front wheel and he does open races as well and to my knowledge noone has ever challenged him about it.

Edit: TLL was asking about TTT, not ITT. Dunno the answer to that, very rarely does anyone from my club do TTT though the option is there at every club TT if you want to. I'm doing an ITT (optional TTT) later on today, I'll ask the Commissaire.

Maybe they call a team TT a "mass-start" race?

If they are on the UCI list of approved wheels then you can use them.

In other words, if your racing in Aus, as long as they are round and the front one isn't a disk, then you can use them.

At the 2011 Masters ITT championships, a number of us (including me) got pinged for the bikes being too long and they weighed them. But no one got pinged on the wheels

There is no regulation in TT events that prevents use of a front disk.

I doubt the bikes were too long. The bar set up however may have extended too far forward of the BB.

However would they let you race with a front disk wheel?

Yeh, that's what I meant, the bars were too long

The problem I had was that the bars were not adjustable, so they let me race anyway

This may come across as a silly question (but do forgive me) but regarding the depth or profile of the rim in terms of the aero fairings on wheels, but where does the actual measurement take place? is it measured from the outer most part where the rim meets the tyre to the tip of the fairing, or is it from the edge of the braking surface to the tip of the fairing?

Cheers guys.
