I want to build a really tough touring wheelset and have found that my best option in terms of shipping and availability are the A719. However my feelings towards Mavic rims are mixed up. I've had very good rims (X618, stilll going strong after many years of service) and really crappy ones (X517, used in light touring and commuting and got cracks around many eyelets).
Some have told me to stay away from the A719 (cracks, thin sidewalls), others like reputed Harris Cyclery or SJSC describe them as high-end heavy-duty super tough touring rims.
So with this scenario it's a bit hard to make my mind up on thiese rims so I'd really appreciate any comments on them.
Best regards.
