View Full Version : Deep rims?

I thought this would be the best forum to ask this. Whats the advantage and intended use of a deep rim,, looking at some 30mm rims. Most of my ridding is alone on the road all summer and doing centuries with the club. Would it be a foolish investment in my ride? This set is only 1500 grams., Velomax Tempest II.Im ridding on Kyrsium Elites now,, I think they are close to 1800 grams. But aside from the wieght difference what else can be expected? Thanks............

I don't think that you'll notice the benefits with anything less than 40 mm.

Take a look at this site for some good info:

I'm going to agree with karesz3 on this. If you are going to go deep dish you will only notice a difference as with most everything else when the change is big. I would say 40-50mm would be a good range with reasonable results. Watch out for those x winds though. It's like a parachute on your wheel.

American Classics had some wheels going...1340 g for under $600 somewhere on the internet. They were 34mm I believe.

I actually use the American Classic CR420 rims with bladed spokes. I love these wheels, and I think they are faster than Ksyriums are, but the biggest benefit comes from the lower spoke count. Since bladed spokes are stronger (higher tension) I'm able to run a 16/20 configureation, so this maybe where the biggest aero difference is. Other than that, they look great, and I highly recommend them.

Cheers
