I'm in the process of building up a new set of wheels. I do some touring and some recreational riding. I've been looking at Mavic rims with machined sidewalls. It sounds like the A719 is a workhorse for touring, but it might be a more stout and heavy (560 gram) rim than I need. I'd like to be able to use 25 thru 32mm tires. Is there a more medium duty rim in the Mavic line or should I just pull the trigger on the A719's? This is my first post. I joined just to quiz tour brains.
