the IRD Cadence rims are
wicked light....and too flexy,
but now they have a 30mm
deep dish that weighs about
what a 'regular' rim would--
does the deep section mean
that it's going to be any stiffer??

Also, what about Velocity aero-
head rims? are they stiff and
straight? i know that particular
model is pretty much a regualr
rim and that's fine--as far as i
know, brings me to the next
question..

How advantagous(sp) is a deep
profile anyway?? anyone really
notice an aero advantage using
said rim?

Many thanks, and please, no
product hors.., i'd like real
answers.

I've built up a set of Velocity Deep-V's and they are excellent wheels. They are round both laterally and radially. So I would expect Aeroheads to be the same. Also from what I have heard, Velocity makes excellent rims.

If you want a really stiff rim, check out the Deep-V's. But you have to consider the extra weight the deeper section adds. My set are built 32 spoke 3x on high flange Phil Wood track hubs and there is no way I can flex those rims in a sprint.
