The belt is impossible to break if installed correctly (ie: snug enough to not slip nubs). Possibly on the downside, I suspect it is a little harder on the BB bearings due to the much higher amount of timing belt tightness needed, though nobody appears to have reported this occurring.

A big plus to the current system is that pricing is finally somewhat reasonable. ie: $50/per timing ring, $50-75/belt, but supply is a bit slow and scarce. I wouldn't be surprised if the new CDX version hits the $400-500 again for the first year or so.
