Anyone have opinions on the Mavic Open Sport rim? Yes it's a lower end, budget rim, but this is going to be for a vintage steel frameset laced to old Campagnolo Record hubs. Looking to get the braking performance of the Open Pro rim which I"ve used (and use currently) on my Gazelle(s) so I feel better riding them in a group. My current wheels have Campagnolo Omega 19 rims (anyone here remember those?) and the braking surface leaves more than a bit to be desired. Thanks.

remember? i still have a set.

Pro sounds faster.

They are known to be rather tough. Guess this means I won't have an excuse to relace these wheels any time soon.

I ran across the description of the Open Sport as the new name for the Mavic MA3 on the Harris Cyclery site when I was looking for a potential replacement rim for an MA3. The MA3 seems to have a good reputation as a durable touring rim... The profile on the site does look similar to my MA3s, so I think the Open Sport would be a good choice for a durable daily rider.

in +/-18 years of serious riding i've NEVER had to relace a wheel that wasn't damaged in a crash/car hit.

A good reputation from whom? The MA3 wasn't designed as a touring rim and I've read numerous reports of cracks around the spoke eyelets in non-touring use and have experienced it myself. If the Open Sport is the MA3, RUN AWAY!

I have both the Open Pro and Open Sport.

I have the Open Pro on a nicer bike of mine. They are great. Solid braking, great looking, light, strong.

I have the Open Sport on my "around town" fixed gear. I rode it yesterday in heavy rain. The braking was ok...BUT, I am using an old single-pivot Dia Compe caliper. And, I am also using some heavily used (2 years) Shimano stock brake pads.

I use a Dia Compe caliper on the Open Pros but have some Kool Stop pads in there. They stop better, but it could be the brake pads.

Also, I am only running a front brake on the Open Sport rims (it is a fixed gear).

Oh, one other comment on aesthetics. The Open Sports have a little notch/valley in them. I'm guessing for brake pad wear indication? Anyway, the rim doesn't look as nice as the Open Pro because of it, but again, this is not related to function at all, and only related to looks.

Open Pro's... Trashed two on yesterdays ride- no crash, no pothole.

Only had them for two months- just over 2500 miles and they are trashed.

Sorry, I can't recommend them.

Check out DT R1.1's instead.

I've worn out several Open Pro rears. The front lasted 5 years, but the rears only about 18 months. When I started riding them, I was 220 lbs though...

thefatguy

200lbs shouldn't kill an open pro.

Peter White builds with the Open Sports, maybe because they fill a niche between narrow racing and full-on touring rims? Maybe because they are the best rim at that pricepoint?

I have no experience with them personally, but I've read the same complaints about cracking at the eyelets. But why would Peter White build with them if this is the case? Maybe his customers don't ride very much...or maybe the above examples were simply poorly built wheels.

I'd take Sun M13II or CR-18s before OS or MA3. For a little more, Velocity's Razor is decent too.

Where'd you get the wheels, ie: who built them? I had a set of Ultegra/OP's from Performance. Had to take them to my local shop to have them trued once a few months after getting them but they were straight after that. My current set are laced to a set of Campy Daytona hubs, weekend before last I slammed a pot hole HARD. Hard enough to pinch flat my Pro2Race tires with 120psi in them. Rim was straight as an arrow afterwards. And I'm starting to creap up there in weight these days.

I think my decision is pretty much made up. Going with Open Pros, 36h, Record hubs (old freewheel style). I'll be using them with older single pivot brakes, which is part of why I'm looking for good braking performance. Thanks everyone for their input.
