Hey JamieJ,
I have only put a small amount of miles on the saddle thus far but I like it. You can really use the entire seating surface (not that there’s much there) without compromising comfort. I have taken some of my comments and questions here…http://www.tririg.com/articles.php?id=2011_07_Dash_T7_Review. I have found myself wanting to ride further back on the saddle though. I currently have my angle set at zero degrees tilt for reference but I might play with it 0.5degree either way once I can get out on a longer ride.
Yes, the cutout is definitely wider than the Adamo/Cobb. That was a big selling point for me over the Adamo. Technically you only need the area for your sit bones anyway. But that brings up another point… I find that this saddle is slightly wider at the nose where the seating area begins. (i.e. where the seat flattens out behind the nose slope) It’s not that much wider but when switching to a new saddle a person tends to be hyper-sensitive to any variations between the old one, especially width. Don’t let that deter you though because Dash has a “narrow” Tri.7 in production and I have one on order! Regardless, I am keeping one of my Dash Tri.7 saddles. The price tag has not trumpted the comfort level for ME.
As far as “slamming” the seat forward, I don’t think you get as much seat rail as you might need on the Dash. For me, I was able to position it in the same spot as my Adamo with a little bit of rail to spare. Granted, my Adamo was only set to the half way mark on the rails. So if your seat is maxed out in the forward positon and you don’t have the option to get a 78/80 seat post you might want to be aware.
Pictures speak better than words sometimes so let me go home and snap some off tonight of the Adamo and the Dash side by side.
