From what I've heard on here, DOB rims don't hold there grind too well as they aer made from magnesium alloy. I've had Ronnies in the past, but they died after a few grind. If your a smoothish rider this shouldnt be a problem. Currently running a Echo 2007 rim which I must say is like a Mavic, only wider (meaning VERY strong) holds grinds well too. I've had the rim for just over a year! which is a long time for me. It has no dents. still as it was a yeaar ago. well i have ground it twice in that time. Id go for a Echo rim.
