Anyone buying a 159gram saddle is concerned about weight over comfort. It was a good price on BT, so I picked one up for the road bike. Weight was spot on on my postage scale.
Just be warned, this thing is minimalist- As in VERY stiff with little padding. My butt is still deciding whether to keep it in service, as I only have about 12 hours on it so far (on the mountain bike). I've had a few minimalist saddles in the past that were sub-200 grams, but none as stiff as this one. It replaced a cushy WTB saddle that weighed in at 310 grams- so saving 150 grams (5+ ounces) is cool. When I put the Cutter saddle on, I had to raise my seat about 1/2" (that's how little padding it has).
Bottom line, if weight weeniness is a priority, check it out. Also worth a look if you have previous experience with minimalist saddles. If you want comfort and squish, avoid this one.
