If they are wear indicators, I can use the rims until they're gone, right? Can't say I've used wheels that have had them before.
thanks
It really doesn't matter if they're wear indicators or not, you can probably use them as such.
The bottom of the groove most likely determines the minimum rim width. If you consider the idea that a chain is only as strong as the weakest link, the added braking surface material doesn't add any strength, so wearing it down to the groove depth can't weaken the rim. Of course there's every possibility that you can wear the rim beyond the bottom of the groove, but at least you know that wearing it to the bottom won't hurt.
BTW- all the above depends on the groove not being where there's added material on the inside, but IME I've never seen one that was.
