Is this the next "MA-2" rim?

OK, many of you lament about the dismissal of the vaulted Mavic MA-2
rim. So, what to do? Ride old Mavic MA40s? Maybe.

Well, has anybody tried the Sun CR18 polished rim? Its a silver polish
rim (like MA-2), double eyelets (another MA-2 favorite), and has a
list weight of 460g (again, about the same as a....say it....MA-2),
Finally, the price is very reasonable as it retails for $36 each.

The one major difference is the Sun CR18 has a width of 22.5mm; in
contrast, the MA-2 was listed as only 20.3 mm wide. Still, with the
demise of the MA-2, this may be *the* replacement.

Or go directly to Sun's website (note, the rim comes in both black and
silver color):

Note, Sun also has a slightly lighter version (405g) called the
Assault that also comes polished.

So, what do you think, do the Sun rims compare?

I'm a big fan of the CR-18, but I don't think it's really comparable to
the MA-2. It uses "triple-box" construction for extra strength instead of
sockets (i.e., it's only single-eyelet). I've never weighed one, but from
what I've read, the 700C size weighs more than 550 grams.

Ok, looking at the picture on the Sun website, it looks like the rim
has only single eyelets as there doesn't appear to be any on the
inside of the rim (near the rim tape). However, the Sun website's tech
section list the weight as only being 460g, not 550g. I wonder if
there is truth in advertising? Brewster

The construction is a little different than the MA-2, but I've been
happy with the CR18 I have on my Bike Friday (451 rim size). One
thing that's especially nice is that tire changing is easier on that
rim than on any other type I've had. The tire pulls off easily
without any need for tools and is also easy to reseat properly.
Oddly, the slightly more aerodynamic Sun Mistral rim on the front
wheel of my Friday is one of the worst for tire changing.

I'm in the market for a new 700c rim and would appreciate any more
feedback on the the CR18 (or other models) in that size. In
particular whether they share the easy tire-changing characteristic
that I've found in the 451 (20") size.

AFAIK, the polish version is to be avoided as it uses a more ductile
alloy than the regular extrusion to achieve the fancy finish, thus is
likely to not build as strong a wheel.

Two good basic strong rims to consider would be the Alex R390 or Salsa
Delgado, both which are socketed. The plain finish eyeletted CR18 is
quite good as well--and if the polish version speaks to your aesthetic
senses, I'm sure it will hold up, if laced tightly, though not my
first choice.

My polished 700C CR-18 rear rim has been abused for more than 5 years
and is finally starting fail along the braking area. It prefers tire
sizes from 25C and up. It seems easier to put on folding tires than
wire beads on this particular rim with less 'bead seating' problems.
That 460 gram claims seems low

The Alex R390 recommended by landotter has been easy for tool-free
tire/tube changes, at least with a Continental Ultra 3000 kevlar
beaded tire. The socketed construction sure made for easier lacing.

I don't recall the Salsa Delgado also mentioned by landotter being
socketed when I built a 559/26" wheel with one mated to an ENO
eccentric hub. I suppose their 622/700c version might be different.

The weenies say 515g:
http://weightweenies.starbike.com/li....php?type=rims

Which is what a good basic road rim should weigh.

I like Alex Ace 19s which come OEM on a lot of bikes. Sort of like a
CR18 with Rhyno aspirations. Wish you could get them without a bike
attached. 510g claimed, so probably in the 530g range. Stupid strong.

As much as I love to hate Mavic, for a pure go fast road bike, you
still can't beat an Ultegra/OP wheelinabox set for lightness,
strength, and value. Tune, peel the stickers, and ride.

515g according to weightweenies for a 36h 700c.

Sun CR 18 comes in many versions, none with sockets connecting inner
and outer walls. Polished version looks good, but it doesn't seem to
hold up as well as the non-polished version.
Velocity Razor is eyeletted and available in silver, black, or Celest.
It is ~1 lb (450 grams), builds well, and holds up well... + it is a low
profile box section rim similar in shape to MA-2. I add this one to the
already good suggestions made by landotter.
