Another question about wheels set...(6 posts)

Another question about wheels set...Seb
Jul 1, 2001 8:42 PM
I have asked about those set of wheels with fewer spokes (such the rolf for instance) few week backs and you guy's told me that the major advantage of those wheels is improved aerodynamic (faster wheels) more than anything else (strength, light weight...).

I would like to know if those kind of wheels can make a bike less sensible to lateral winds and if so what kind of improvements could be expected???

I got my first road bike ever 1 month back, rode it a lot and noticed that it is fairly more sensitive to lateral winds than any mountain bike that I have riden on road. Of course I go a lot faster now which may somewhat explain the situation but I also tought that the fact that the wheels of a road bike have a larger radius may make them more lateral wind sensitive... The wheels that I currently have are basic Mavic CXP21 rims with unknown spokes mounted on Shimano Sora hubs. Those are old fashioned wheels with a lot of spokes...

Any imput would be much appreciated!

is my take on your situation. The surface area of the rider and the higher center of gravity of the road bike [than your mt bike] is probably what makes it seem like you're blown around more. The bike just reacts different. A lot of times it's the rider that makes more difference than the wheels - or any other equipment for that matter. Just my 2 cents...

Interesting point of view but how am I supposed to react to lateral winds to minimize its effect???

Some of your crosswind instability may come from inexperience. Learn to relax on the bike, ride with your elbows bent. As you ride more in crosswinds, you will learn to better hold your line. Also, head set adjustment can greatly affect the stability of a bike. It may be that your MTB and road bikes have significantly different steering geometry, which also affects stability.

I have the Rolf wheels. On windy days I get moved around a little. I'm not sure if it's the wheels,the bike, the rider, or a combination of things. I dont think much about it anymore. I do pay a little more attention in certain areas where I know I will probably get rocked.

I don't think spoke counts per se would not alter your bike's sensitivity to cross winds. If anything having fewer spokes should slightly improve your bike's stability against cross winds. With that said, I feel noticeable difference between wheels with different rim heights. My shimano R535 with 28mm rim section catches whole lot more cross wind when compared to Velomax Ascents with 21mm rim section. This effect is compounded by aero-shaped spokes on my shimanos. Aero spokes are nice weapon against straight head wind on the flats and does allow me to keep my speed up once I get it up to 25-30 mph. But I've noticed that it does adversly affect the bike's handling when I'm exposed to strong cross winds.
