During late 90's, some MTB's, the rigid and cross country type are putting aero cover on their rear wheelset. Now it's becoming a trend again here in Laguna especially the XC's set up. What is really the benefit of that, does the wind really pushing your bike to the max, or the wind will stop you because of that umbrella looking wheelset? the reason why recumbent bike uses aero wheelset is for maximizing speed through the principle of aerodynamics? is this true?

;D Uni covers where the original brand aero covers. In the 90 they were the boom along with aero bars. This was brought about by Greg Lemond's fantastic 8 second come from behind win against Laurent Fingon the 1989 Tour De France . He sported a mavic disc wheel and Scott aerobar while Laurent Fingon used also Disc wheel but a cowhorn handle bar. Everyone sported an aero bar and disc wheel cover then even mountain bikes after his win. the benefits of the disc cover is that then are similar to disc wheels but lighter and alot cheaper. You can use your exisiting wheelset. Benefits of anything with aero equipment the faster you ride the more benefits you get. with disk wheels you get about 2% to 4% more speed more or less depend on conditions. They are a bear to use on the crosswinds by the way. i only find them worth it on long solo ride road rides and time trials. Plus our seating position on the mountain bike is aggressive not as aerodynamic as road so the benefits are negated. See the link : freespace.virgin.net/martin.shakeshaft/aero.htm take alook at this article with mention of use with mountain bikes.

Thanks, so this will benefit road MTB's of course not on the off roads, I'm thinking installing one to my rigid mtb, some folks here in southwoods are installing this old school set up, and it adds great look on your bike.

They are not that heavy as the covers are vinyl and the hoops you attach to the wheelset are made of Aluminum. I got mine in 1989 for about P1000 dont know how much they go these days and where?. ;D

Tioga had aero wheels a decade ago. Never took off. The claimed benefit of aero wheels is the reduction of turbulence in the rear ... at time trial and track speeds.

LOcal folks here in Biñan and Cavite just customized it ( home made heheheheh but in fairness, it's very nice with UNI printed on the black vinyl )
saw one in Cartimar store, original SALE daw about 3.5K orig UNI, Tioga's ( fabricated ) P1000k up, generics, 1K below

but i guess this will only fit standard rims, not suitable for aero rims like Mavic Dee Max, ASafety Line rims at GTS WSB rims.

Actually Tioga wasnt really a aero disc wheel per sic as it did not have the lens shape. It was made by replacing all the spokes of a standard wheelset by Kevlar strings strands. then a flat round material in the middle. It was supposed to have rear shock absorbing qualities. It was used by John Tomac for 1 full race season in NORBA but discontinued it's use.

Indeed. It looked like a rim with a ball of yellow twine wound roughly through the spoke holes. ;D It was also used in a trans-Russian tour. It held up well. Wasn't too much of a commercial success though.

I've read from another website the effect of this cover, the speed advantage due to being aero was very little as compared to having your legs shaved. I may ont be right because I did not actually tried it. But maybe, another advantage for this is it helps to keep your wheelset (the rims, spokes and hubs) clean.

This is a wind breaker... A big advantage if the wind direction is heading. Disadvantage if the wind direction is from the side...

Try bombing down Bugarin on a windy day with one of those and see how unerving it can be.
If aero covers are making a comeback, isama na rin nila yung mga neon colored stuff na na-uso during those years. Purple anodized bar-ends anyone?
