    Looking for rim same width as Mavic A319 but lighter

    I commute on a touring bike that came stock with Mavic A319 rims (24.5mm wide, 597g). I'd like to get some lighter wheels to commute on and leave wider tires on the stock wheels for rides on rail trails. I don't want to have to screw with the brake pad adjustment when switching between wheels.

    Any rims 24.5mm wide that are significantly lighter, like in the 400g range?

    Small world - I'm wondering the same thing - with an eye toward building up a set myself. I love my Randonee but it is heavy - I think the wheelset and stock rubber are relatively heavy. I had troubles with spoke breakage, so I have rebuilt the rear wheel with butted spokes, and the original hub and hoop.

    I'm thinking the rack may also be heavier than necessary.

    Hey fholt,

    Where in NC are you?

    I have not had any problems with the wheels on my Randonee. However, I do not load it down that much, I'm 175lbs and the most I carry on the rack is maybe 10-15lbs. I agree the rack is overengineered, but I would appreciate it on a loaded tour.

    A store bought option is A719 rims with Shimano 105 hubs from Performance (they are 36 spoke wheels). The listed weight is similar to the open pro/ultegra wheels they sell, but I am a bit suspicious of that, they state the A719/105 rear wheel is 24g lighter than the OP/105 rear wheel. I don't see how this is possible since the A719s weigh 132g more than Open Pros.

    At 400g we're talking racing rims and there aren't any that wide.

    I wouldn't want to use racing rims for loaded touring because larger tires would get squirmy on a narrow rim when heavily loaded. Spoke fatigue and subsequent breakage on an unsupported tour is also something you don't want happening on a regular basis.

    The best I found in an eyeleted, 36-spoke, 22mm wide, machined sidewall rim were the Bontrager Mavericks at 485g apiece. They are actually discontinued 29er mountain bike rims. Salsa Delgados are also pretty tough at 22.5mm wide and 510g apiece if I recall correctly.

    If you're going lightly loaded, lacing up some 36-hole CXP33's and sticking to tires no wider than a typical 700x32 would be an option. With obsessively well tensioned spokes, I don't think I could hurt them. At that point though you'd have to ask yourself "Why such light rims on a frameset that must come in close to 10 lbs?" A 6 lb. Soma Double Cross frameset may well offer better bang for the buck.

    No matter how you set it up, a Randonee is never going to get very light or very fast. I upgraded my Jamis Aurora from top to bottom with parts I already had (mostly Ultegra) and after dropping almost four pounds from the bike, it still weighed 29 lbs. I could drop another pound but what's the point? It's the heaviest bike I own and that includes the old school bomber and the full suspension bike. I love it though. It's the only one in the stable that will let me carry things like car batteries, bowling balls, and watermelons.

    This is for commuting, I stated this in my original post. Not loaded touring. Figure no more than my weight (175lbs) plus 15lbs max of stuff.
