Tough to find a sort chainstay mountain bike these days. All the hardtails seem to be stuck in the 16.9" range, and the full suspension bikes aren't any better because shorter chainstays usually mean a bit less travel.
Hope to get my AlpineStars back on the trail soon.

Fisher's Genesis geometry uses shorter chain stays. I can say from experience they climb quite well.
