This will be the last time I come to this well over this issue, but here are 3 more pix of the failed rim sawn in cross-section. Pretty alarming! Look here:

Even a rough idea such as "half of original; quarter; or thin as a soda can" may be helpful when the rest of us check our rims. Given the dimensions that Grant lists, I should pay a lot more attention to rim wear. My replacement cue has been when they're been banged up enough they won't true up. The current Mavic A719s on my Atlantis rarely need any attention but the braking surfaces have noticeable wear (now that I'm looking). After reading Grant's dimensions for the upcoming Stouty rim, I checked Mavic's website for comparables on the A719. They only list weight (565 grams for 700). tire width (28 to 47), but not rim width or height. IIRC they used to have more detail. The next level down for touring is the A319 @ 595 grams. So Grant's 650 gram is right on target. Most of us are going to mount tires in the 600-900 gram range so another 50-100 grams of rim is worth it for a stronger, longer wearing rim. dougP -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
