The Good: Weight. I'm no weight weenie but this thing is pretty light, for those that care. Comfort. Very comfortable saddle that I take on long rides. Titanium rails are actually pretty compliant, great for my hardtail. Padding is enough to make 20+ miles bearable.
The Bad: None that I can spot.
I have had this saddle on my hardtail for the past 5 years. It has stood up very well, still comfortable. I just started to develop a hole in the kevlar side a few months ago, which I consider a huge win for the number of miles this thing has. Wish I could find it for the cliamed $72.35here in the states, I'd pick up 2 of them!
