I am able to get the Open Pro rims or the CXP33 rims for the exact same price. 2 stores, same price, different wheels. Which ones should i get. The CXP's are a little heavier but are full aero design. The open pros are a bit lighter but not aero. What should i get given they are the same price.

well, lighter rims will accelerate quicker, and more aero rims will shed seconds over a longer period of time. Will you be racing, or training with these? If racing, crits, or longer distances??

I was faced with the same choice, Brian. It depends on your needs, obviously. I live in a rural area with patched-up (read: potholed) roads with lots of level RR crossings. My wheel builder said that the CXP33s would stand up better to those conditions than the Open Pros. The aero shape is just stronger. Thery have performed better than I could have imagined, and they look great, especially in black.

The Open Pro is bombproof enough. The CXP 33 does not provide enough of an aero advantage to justify the weight difference (I read this in RBR), so I would go with the OPs.

FYI, I used OPs for almost 2 years, and I can say that they really are bombproof what with all the potholes I have hit.

Do not forget that aero rims require longer tybe stems....and that can be a pain.

The 33s are not aero enough to make a difference,but the profile makes them stiffer and stronger IF you need it.

well torontos roads are all ****ed up

Not as ***ked up as Philippine roads. My OPs survived the deepest potholes, and I am currently using them as a back up set. My main set of wheels are the Formula Xeros....tough too with the Velocity Deep V rim.

Brian,
I think its not really that******ked, , if your riding in the city of Toronto, I would grade it at 7 in a scale of 1 to 10, 1 being the worse and 10 the best road, and considering , the road in a third world country, Toronto's raod are a heaven's gift for cyclist, do /or do you not agree with me Brian

Go with the Open Pros. Bombproof if built well. Any rim will suck if it's not built well, but the Open Pros will be all you'll need. The CXP's put a lot more weight (for an aluminum rim) at the outside of the wheel, the worst place you can have it. Not enough difference in strength to make up for the weight, IMHO.

I'd say the Open Pro's. Like mentioned, the aero profile isn't enough to really help. The weight difference will help you more. The Open Pro's seriously are bombproof, which was also mentioned. I wouldn't worry about either giving out on you, really.

I just had a set of wheels built up for my winter (road) bike. After working things through with my LBS I decided on CXP33 rims, DT double butted spokes and, for a twist, Shimano Deore hubs. After a few miles of riding, I can say that I'm very happy with them. OK, so the aero profile of the CXP33 is not very deep, but this means that tubes with standard length valves are OK. The result is a nice stiff set of wheels. They look nice too .

The previous wheels on this bike were built with Rigida Nova R rims. These showed serious fatigue cracking after 18 months, so the choice of the tough CXP33 seemed like a good idea in my case. OK, so cast me out of the road cycling forum , but the Deore MTB hubs have much better sealing than any similarly priced road hub from Shimano and seem nice quality - the hub body is the same pattern as the Sora model, but the innards are much better protected - something I need whilst commuting in the winter.

Just my two-penneth,

Mavic cosmic Elite for me, but if I have the extra moolah I would go for the mavic Ksyrium Elite or the SSL

This thread has been going on for several weeks already and I'm sure that Brian has long since bought his rims and had his wheels built. I'm sure that in either case he has a great set of wheels. However, today, I asked the folks at the Colorado Cyclist what the actual difference in weight between the CXP33s and the Open Pros is. Each CXP33 rim weighs 470 g as opposed to 425 g for the Open Pros. I had to translate that into something I could feel. So I put socks on the scale. A pair of socks weighs a little less than 45 g. So I guess that a pair of CXP33 rims weighs about about 5 socks more than the Open Pro pair. I can live with that. But that's just me.

5 socks heavier, but no added benefit over the Open Pros.

Open Pros win over the CXP 33s....unless you are a 250 lbs. Clydesdale.

Yup i got the open pro with chorus hubs today. Love it.

I vote Open Pro. I'm riding a set and love them.

Yup, that's me all right! Neighhhhhhhhhhhhhh. Clomp, clomp, clomp, clomp, clomp, clomp, clomp, clomp (the sound of me trotting off in dejected defeat).
