Terry Fly Ti on my hybrid (GF Kaitai) and trainer (Scott Santa Fe), and Selle Italia SLR Gel Flow on the roadbike. The Terry Fly is an AMAZING fit for me. If it were just a few grams lighter, I would have one on my roadbike. On an older roadbike, I used the Fly for commuting 38 miles a day year round for three years as well as metric and english centuries with zero discomfort. That being said, all sadles take a little dialing in for fit, but I would have no problems if the Fly were my only option.
