Both rims have the same outside dimension of 20 mm, but according to
VelocityUSA where I asked, the inside dimensions are 13.35 mm for the
Aero and 14.0 for the Aerohead.
That is a substantial difference and was wondering if anyone has either
or both rims and could comment.
I plan on building fast commuting wheels and using tires 25-28 mm.
For comparison, I have old MA-2s that are 20.5 and 13.8. These size
tires are really great for this rim.
Obviously, the Aerohead at 14.0 is slighty wider than an MA-2, so it
should be fine with those tires. But that rim is pretty light at 405 grams.
In contrast, the Aero is quite a bit narrower inside, but is more heavy
duty at 480 grams which appeals to me. But the narrowness doesn't. It is
surprising that the Aero is touted as excellent for cyclocross and
touring given that these types of riding involve larger tires.
I wish the Aero had a 14.0 inside dimension. I think I like the shape of
it better too.
