I currently use a Cobb 55 on my TT bike. Started with a Fizik Tritone, but the Cobb was far and away more comfortable for me.
Might do a little racing, but I am mostly riding long to train, 25-200 miles. I used a Cobb Plus previously. It was ok, but not perfect. Most comfortable saddle I have ridden was the Selle Anitomica, but doesn't really go with this type of bike.
Thanks for the help.
