One of the Avid Shorty 4s that came stock on my bike several years ago has given up the ghost. Apart from my love affair with my Clement PDXs, I am not a gear head. I am a bit bewildered by the array of choices out there now. So, I'm coping out and looking for recommendations. Desired features: relatively strong stopping power (off season my 'cross bike gets a lot of use on the road, including mountain passes, etc); relatively easy adjustment (including something akin to barrel adjustment to accommodate different rim widths without moving the cable); and moderate price (not bargain basement, but I'm not looking for latest and lightest just a solid, dependable brake).
