    Sun Double Track or Mavic EX729??

    I'm about to get a wheelset built up around Hope Pro 2 hubs but can't decide between the Double Track's and the EX729's. I'm riding a pair of 729's on DMR Revolvers at the moment and have no complaints, so would have no problem going with the Mavics again, I just like the aesthetics of the Double Track. Weight isn't an issue, I'm just looking for some idea as to the comparative differences, if there are any of particular consideration. The bike is built on an '07 Big Hit frame, my riding is freeride and split 60/40% urban/trails, so there's quite a lot of square-edge stuff and unforgiving landings when I get it wrong (which I do with some regularity), although I'd consider myself to be a fairly smooth rider most of the time.

    Is the Double Track a worthy contender? Or do I stay with tried and tested?

    Many thanks in advance for your help.

    Go with the 729s if you haven't had any issues. The Double Track may be strong... but it is MUCH heavier.

    double tracks (the Sun Mag 30) are really strong rims, but they are heavy,......you say you do not care but weight but it does matter.....if you are building...why don't you go tubeless with823's

    I've no experience with tubeless. How would my tyre choices affected? Any other considerations?

    You can still run tubes with the 823s if you'd like. Most non-UST tires can still be used as tubeless with a bit of Stans.

    you need a air compressor and some stans no tube juice....mount 1/2 of tire and add 2 scoops of stans......then fully mount tire......take soam soapy water (car wash/dish soap) and wipe rim and bead of tire.....then fill up with air.......good luck....michelin tires work the best

    I built a set of 729s over christmas. I still need to weigh them. I'll try to post tomorrow.

    DT comp spokes, alloy nipples Ringle Abbah front hub and a generic rear 12x135
    It was going to be Hope Pro II, but the blue ano was back ordered

    Very light, crazy stiff.

    Doesnt the Double Trac weigh 800g for the rim alone?

    Mavic's tend to build up easier and require less truing in my experience. If you are building the wheel yourself go for the 729. They're burly and they build up really well.

    729's are boss.

    Sun Double Tracks/Mag 30's are just ridiculous. If you need wheels that strong, you need to reconsider your riding abilities.

    Yeah for real. I see reviews for the Double Tracks that say: "These are tough rims...I've cased like 10 times and they're perfect!"

    Solution: Do not case jumps.
