Are Open Pros tough enough???

Bike: Surly Cross Check 9 speed double
Tires: Scwhalbe Marathon Supreme 700c x 32
Me: 185 lbs

Ride: Michigan Road (tons of potholes), MUP (cracked, broken, washboard, holes,) occasional gravel and hardpack. I want to be able to jump the occasional curb!

Seems like Open Pro/Ultegra is not meant for this much abuse. Is Velocity Dyad a better choice? The dyad is a bit wider than I was shooting for, and is much harder to find.

Umm, I'm 235 lbs and I've jumped curbs (and potholes) with my MATRIX rims (you know, cheap a** bottom of the barrel factory junk wheels with tinfoil spokes) and they're still not unrideable. They ain't true but they are still rideable. (I just put 500 miles on them in the last month.***)

Open Pro rims are used by mtn bikers who don't want to taco a wheel back of beyond. I wouldn't recommend the cheap ones at Performance Bike though. Instead I'd say to get a good handbuilt set with quality spokes.


***Reading this tells me that I really need to get a set of new wheels.

Build quality is the key. I had some low level Mavic CXP 22 rims laced to Shimano 4400 hubs. Put maybe 4000 miles on them with just one minor truing.

the mid v profile of the Mavic CXP33 or their cheaper CXP22 will give you a tougher but heavier wheel.

Thanks for the input so far... CXP33 looks interesting. I was originally looking at the A719, but they are really pretty hefty.

If you want a bombproof option, look into the Alex DA28. Cheap, $50 or less and really strong. You can also option the velocity deep v among others.

Don't look for box section rims if you're looking for strength. Which shouldn't be too hard nowadays anyways.

If your looking at the CXP33, you might also look at the Velocity Deep V's. I'm a large guy, 300 and I have the Velocity and they are a strong stiff wheel.

The Deep V's seem a bit narrow for my 32mm tires. I'd like to be able to fit 25-35 mm tires on these rims.

I currently have Alex DA16. I would like to try something else.

Now I'm thinking Velocity Synergy!

I'm only 155 lbs. but I beat the living tar out my Open Pros (28h front, 32h rear) and build quality is indeed the key. I've done cyclocross and a couple of near one foot drops off tall curbs with a light rack and Nashbar Daytrekker panniers on them. I'll probably roll over to 3000 miles in two weeks and they've yet to need truing. I'm hope to start bunny hopping cross barriers on them soon as well.

I ride pretty rough rural roads. I'm 195 and have had these results with variour rims:

CXP 33 32-spoke (machine built wheel): Eventual cracks around several spokes (rear wheel)

Open Pro 32-spoke (hand built) - dented sidewall, flexy on big hits like potholes

A 719 36-spoke (hand built) - bulletproof and will take 28mm and up.

Heard good things about Velocity's designed for touring

I find even tubular rims well-built to be fine for Michigan roads. You have to WATCH for the potholes and crap and steer around them. When I was a good rider many yarns ago I could bunny-hop curbs, and of course that does nothing to the rims, at 150# in those days. Now I don't hop it so neatly, and my rims have still lasted a few years each. I've weighed 180 for the past 5 years or so, been riding all through this period, and no tacos or dents.

I think you're missing the point of a Cross Check with 32mm tires. My Cross Check is about going wherever the **** I want (in particular, MUPs where roadbikes dare not tread,) not avoiding obstacles.

I will avoid potholes on my road bike (and even then, it's not always possible.)

Points taken, but be aware roadbikes do dare tread on MUPs. We probably pass you so fast you don't notice (lol!), so your comment is understandable. I personally ride mine wherever I want, but I don't want to go offroad or off pavement.

Dyads hard to find? I don't think so. Try Peter White.

For what it's worth, when I laced up the Dyads for my tandem they built up better than any other rims that I've ever tried (and I've built a good number of wheels). After tensioning neither wheel required any significant amount of trueing. I was over the moon.
