Deep V vs. Sun M13/CR18 vs. Mavic Cxp22

So I'm looking into building up a new wheelset for my fuji. I'm caught between the Deep V, the Sun M13 (a narrower version of the CR-18), and the Mavic Cxp-22s. I'm looking for a very tough and sturdy rim that can carry my 200lbs over the sh!tty roads of brooklyn and manhattan. I don't have the money or time to constantly be bringing my wheels to be trued so I need something tough that will last me. I like the Deep V because theyre supposed to be one of the toughest rims available, but they are a little pricier than the others, heavier, and a little played out. The Suns look fairly classy and are inexpensive, but I dont know how durable they are. The Mavics are sort of my last choice between the three, but they seem to be tough and relatively light, and fairly inexpensive. The wheels will be built with DA hubs and dt swiss spokes. Thanks

Box?
Open Pros/ Open Sports.

Semi-aero?
Aeroheads.

My current personal preferences.

cxp22's regularly come stock on cheap machine built fg wheels. I'm sure its OK, but it sorta defeats the purpose of going custom. Why settle for a lesser rim?

OP, you won't find a better rim for your purpose than a cxp33.



I've built wheels with CXP 33 and gotten very good results...straight, true, bombproof wheels. For what its worth, I haven't gotten quite as good results with sun CR18 rims. They seem to be more difficult to achieve even spoke tension without the wheel being a little out of round. Nonetheless, the sun and mavic rims are both very durable.

OP, whatever rim you go with, its more important to make sure the wheel is built properly. Your earlier wheelest is/was probably undertensioned, which explains why it might have needed repeated truing. When spokes are undertensioned, they go totally slack at the bottom of the rotation, allowing the spokes and nipples to gradually turn, allowing the wheel to loose its true.

Even with a considerable amount of pounding, a properly tensioned and stress relieved wheel will stay true for its entire life.

Good luck!

get lots of spokes (36H)

spend a lot of time trying to get your spoke tension really even. Also, use some brass nipples so you can really get those spoke nice and tight (and even, that is the most important thing.)

ok revised my options, now im looking at Open Sports, Aeroheads, Fusion, Cxp33's, and Sun m13s. I like the idea of a box shaped rim, but I'm concerned about durability...what do you guys think is the strongest box rim? Also considering picking up a set of used Campy clinchers--they go for pretty cheap on ebay and I hear good things; any comments on their durability?

Here's my $0.05 on those rims: the open sports are pretty much the low end of Mavic's offerings. They aren't maxtal, nor are they welded. The aerohead's are known to be very light, but I don't think Velocity rims are on the same quality level of Mavic. I currently run a 36H CXP 33 rim on a Dura Ace hub for my front wheel. The rim is strong, fairly heavy, semi aero, uses maxtal and is welded. Personally, I think the CXP33 or aerohead are the best of all your choices; however, if you're willing, I'd take a serious look at the Open Pro. Its completely different from the open sport, WRT quality.

From what I heard the Open Sports are jsut a beefier version of the Open Pro's, which is what Im looking for. Open Pros look good and are pretty decent rims but aren't durable enough for a big guy in the city. The CXP33's are the most expensive rim of my choices and I really don't dig the looks too much, I'd much rather have a box or deep profile rim.

What are the strongest box profile rims available?

You have it backwards - the open pro is MUCH stronger than the open sport. The pro uses Maxtal and has a welded joint. It also has double eyelets. Get the open pro - you can't really go wrong with it.

With dura ace hubs, I say go for the Deep V. They are the strongest. And with those nice hubs, you should put on nice rims too, not some ****ty CXP22's. Ok well they aren't ****ty but they are cheap (I got my pair of wheels for $120). Yea i think anything other than Deep V's would be a shame for the hubs.

CXP23s are probably pretty close to Deep Vs in quality. There are two reasons to buy the deep v:

1. You like unnecessary weight.
2. You like colour.

check out the clydes forum for strong rim choices. the typical favorites are:
deep v
open pros
cxp-33

the open pros and the cxp33 are both eyeleted rims.

my friend has some wienmans (can't spell, and don't know the model) that look similar to deep v's. they have held up well to his abuse so far, but he is only like 150.

whatever you do, the more spokes the better. also, talking to a wheel builder in town, he prefers splined nipples over brass- you can get REALLY high tensions if the rim can handle it.

Weinmans are for if you REALLY like color + weight. And wanna save $50.

Low end Mavic is still better than the sun rims. OP are stronger. The Open Sports are $30 cheaper per wheel, but if I had DA hubs, and wanted box rims, I'd go ahead and get Open Pros.

If I had Formula, etc, and was building, I'd go Open Sport, just cuz nobody sells them prebuilt. And they look good.

OP, more important than choosing between any of the perfectly fine choices you've picked out in rims is the spoke count and quality. 36 spokes done 3-cross will get the job done. 14 gauge Sapim Laser spokes are super strong. Sapim Link

I've got Open Sports on one bike and Sun CR-18's on another, and Velocity Aeroheads on another. The Suns look the most retro with their high gloss finish but all three are great wheelsets. But like Sneaky said, if you've got DA hubs, spend the money on some Open Pros and Sapim Laser spokes.

Thanks for the comments. I really like the look of the OP's, but I've heard a lot of bad things about them as far as durability goes. DA hubs can be purchased pretty cheaply on ebay, or for a similar price I could just go with newer Ultegras...basically I'm trying to build a nice all around wheelset without breaking the bank. I intend to find a good wheel builder and probably will go with 36 spoke in the back and 32 or even 28 in the front (depending on his reccomendation). It's interesting that everyone is saying that OP is stronger than OS, everything I read in other BF posts says otherwise--basically that the OS are stronger but heavier than the OPs. I dont mind the extra weight since it translates into extra weight in my wallet as well. I'll need to do a bit more research...

here's some of what i read:
Quote:
...the Open Sport would be a better choice than the Open Pro because of the internal structural support in the rim. The Open Sport is slightly heavier than the Open Pro because of the beefier structure.
Quote:
The open sport rim may actually be stronger than the open pro because of the 2 round extrusions within the box structure. They are heavier because of this. They do not have the welded joint, just sleaved, thus the lower price per rim. Most loaded touring bike builders would recoment the open sport over the open pro as weight carrying ability is prefered for this application.
...
Quote:
I assembled a set of wheels with the Open Sports (formerly MA-3) and 32 DT 2.0-1.8-20 spokes laced 3x fore and aft on Ultegra hubs to be used for light (supported) touring. They are on a Trek 1000 with an 8 speed Sora drivetrain. They have performed flawlessly under my 6'1" and 204 lbs self for well over 1000 miles. Very easy to build with as they seem to be less "flexy or picky" during building and truing process than Open Pros.
Hope this helps..........
Quote:
I would say that Open Sports are perfectly acceptable for at least as many Clydes as Open Pro's are. Cheaper, too. A bit heavier, though, if memory serves.
I like the OP's and Performance has them for like 200 laced to Ultegras, which would be sick if they had a fixed rear option. I would just get those and then have them trued/rebuilt at a reputable shop. Basically I really want to keep this build under $300, which seems like it would be difficult if I had to get new Open Pro's for $70 a pop

edit again:
Performance has a 32x Open Pro with Ultegra for $120, if I were to get that and another OP rim, spokes, and a used ultegra or da track hub, I may be able to stay under my $300 budget
