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.
