SDG Components’ Bel-Air saddle is a classic. It has been around in one form or another since the 90s and here we are with version 3. There have been quite a few iterations of the SDG Bel-Air saddle, but this one earns the V3 moniker because it’s a bit different this time around. The team behind the Bel-Air took modern bikes into consideration, especially now that seat tube angles are getting a lot steeper than they used to be. They took a look at how the pelvis sits on these new bikes and how the contact with the saddle has changed over the years. Besides changes with modern geometry in mind, they also used more modern manufacturing processes. In this review, I’m going to lay out all of the differences, what makes the SDG Bel-Air 3.0 unique, and my thoughts sitting on it.
