    Mavic a719 or cxp33

    I ride a 2011 Giant Defy 1. The stock wheelsets are pretty garbage when it comes to hills, and even light touring. I destroyed the rear wheel with a 300mi ride with 40lbs of cargo.

    I mainly do light touring expeditions, but also enjoy fast century rides. I cant afford multiple wheelsets, so i need one that can do it all.

    So the options ive given myself for a new setup is the a719 or cxp33 with a deore xt hub.

    I know the a719 is known as the "bombproof" investment, but im concerned about the larger width of the rim and the fact that it takes 28c+ tires. It would definitely be a tighter fit for my bike. The cxp33 is made the same (Maxtal, SUP, UB Control) making it an amazing rim, holding a comfortable 23c-28c tire, but is not intended for touring. There is also no concern about its fit.

    Its been suggested that a 25c on the a719 would work, but problems like potholes could easily put a banger on the rim with such a small tire. I don't know if im comfortable with that. Opinions??

    Given these factors, and the intention of never doing any heavy touring (nothing over 40lbs), would a cxp33 36h rear wheel be a wise decision?

    Are there any other options that would suffice?

    The_Real_T_Mac, Among roadies the CXP33 is a hella strong rim. Another possibility could be the Sun ME14.

    All I run are Mavic A-719 and was glad the day I had them made for my 2008 Fuji Touring Bike I absolutely love them and can't kill them.

    You've already said it yourself The 719 is a wider rim designed for wider tires for loaded touring. If you have no intention of runing wider tires then look at a rim better suited for what you have in mind.

    I have mavic A719's myself and run wide tires on them. Personally I wouldn't run anything less than a 28c on that model myself, but someone else might.

    What is the range of tire widths you intend to use? if your frame doesn't have room for much past 28mm, the CXP33 would be a better option.

    +1, but it depends. How much do you weigh? A lot of us consider 40 lbs of gear as "fully loaded".

    If you are not too heavy, get the 36 hole rim, use good spokes,and have it built by a good wheel builder; the CPX 33 should work. FWIW they are also 17% lighter, 470 grams vs. 565 - about 3.5 ounces. Probably not a big deal. Your weight is probably the most crucial factor.

    My wife and I have done a lot of loaded touring on 28mm tires. They work fine for most conditions.

    Starting point of a 5 mile descent on gravel with 28mm tires and Mavic rims (A319).

    My 2007 Sirrus drop bar conversion has 32 hole Mavic CXP 33 rims on Ultegra hubs and it seems to hold my 240 pounds of person, and cargo quite well.

    Velocity Dyads would be about as strong as Mavic A719s and stronger than CXP33s at about the same weight as the CXP33s. Velocity A23s are another good option and lightest of all, but not as strong as the Dyads. I have run 25s and 28s on my Dyads with no issues. Another great rim is the DT Swiss 465. My wheelbuilder says the DT 465s in 32H are as strong as my 36H Dyads and I'll take his word for it.

    Your weight makes a difference. I weigh 200lbs and am I'm real good at breaking spokes. I use the a719's with a 35c tire.

    Whatever wheel you buy, be sure and use the 28c tire when touring. Wider tires help protect the wheel and they soften the ride a little too.

    Before I knew better, I did a 1200 mile tour with 25c tires and absolutely destroyed the wheel by the time the trip was over. It was fast though!

    I've got Open Pros on LX hubs for my "light tourer". 700x28 tires. I've done credit card touring in VT. My wheel builder said they would be fine for what I do, but I was wasn't sure. I hit some pretty good bumps at speed and was pretty nervous about it, but at the end of a week, they were still true. I'll be doing another such tour this June. BTW, me+bag weighs in at about 275. I don't know how the cpx33's compare to Open Pros, but I'm satisfied.

    I know this may be an off the wall recommendation but take a look at the Mavic Aksuim. Recommended for 19-32 tires and was told they will handle up to 300 pounds. My CF bike came with a Aksuim wheel set and I put 3500 miles on them and then moved them to my SOMA Stanyan which is set up a a light touring bike. I also have a T217 wheel set for the Stanyan but prefer the Aksiums.
    I have a A719 wheel set on my full on touring bike but that is a very heavy wheel set and I run 40mm tires on it. BTW I clock in at 230.

    I'm 250 lbs and tour on 36 spoke a719 wheels with LX hubs. My tires are 35 Schwalbe Marathon Racers.

    I have found this to be an excellent combination.
