I picked this for my frame set after taking some long test rides on CF bikes. I'm just as fast and way more comfortable on Columbus steel. For me, it's not about "Classic Looks" or CF vs Steel. I've got a CF fork and a CF seat post, I've tried to take the best of CF and the best of steel. It's a sub 19lb bike that rides like butter. I think it's just a smarter choice for me.
Saturday, I rode on some of the worst roads around here. These are the tank tracks that Rouge Roubaix uses for it's spring classic. One of my buddies looked over at me on a brutal down hill and said "**it you're not even bouncing" .
Sunday I rode a MS training ride where we averaged 19.97 MPH for 50 miles. That's about as good as it gets for me.
One a minor note, I don't care for all the marketing stickers and my Wabi doesn't have them.
CF, is a great proven material that can be quickly pulled out of a mold. Very convenient to manufacture. My bike was hand welded, takes a skilled person to do that. Very inconvenient to manufacture.
All the above is why I picked a build like I did.
