Comparing a comfortable, touring saddle and a light, stiff race saddle doesn't have to resemble putting a pillow and a brick side by side. It can, but manufacturers like Ergon have managed to construct saddles that focus on comfort without sacrificing a race able weight by using effective materials and strategic shaping. The SMC3 Pro Saddle is a shining example of this method. It's the top end offering in Ergon's mountain specific SMC3 line. It's also the lightest, designed maintain comfort across a day exploring snaking singletrack or punching over rocky cruxes to maintain a gap. Ergon sets the SMC3 Pro apart from its more budget friendly siblings by including a carbon composite shell atop its lightweight TiNox rails. TiNox is a blend of stainless steel and titanium that's produced in a single, Austrian factory. The blend is actually lighter than standard titanium, but it retains the strength of the wonder alloy, making it an even better choice for racing kit like the SMC3 Pro. In addition to brining the saddle's weight to a claimed 220g 15g lighter than the SMC3 Comp the carbon shell absorbs trail vibrations. When combined with a layer of Ergon's AirCell padding, the shell creates a saddle that acts as a reliable barrier against bumps and harsh trail noise. Unlike its siblings, the SMC3 Pro also boasts a silicone treated nose for less friction on clothing, and it's shaped to reduce chafing and guarantee ample leg clearance. Like the other SMC3 models, the Pro is finished with a pronounced pressure relief channel down the center to achieve a balance of support and relief.
