As much as we would all love to have a different bike for every type of riding occasion, most of us can't afford to house a lightweight climbing rig, endurance mile grinder, and super stiff criterium racer without some serious financial repercussions. The Fenix SL Ultegra Complete Road Bike is for cyclists who want a bike that's competent in competition, but doesn't sacrifice ride quality in pursuit of weight loss or stiffness and aerodynamics. Put through its paces on the grueling cobbles of the spring classics, the Fenix SL is a proven jack of all trades that will revel in any road environment without punishing you for riding anything less forgiving than smooth tarmac. This Fenix SL carries over Ridley's updates to the venerable frame that was updated in 2017, and is built from the same 30t and 24t high-modulus carbon fiber as its predecessor. Ridley claims this version of the Fenix SL is 15% lighter and 18% stiffer, and any number of reviews and the fact that Team Lotto-Sodual campaigns the spring classics aboard this frame assure us that these gains don't come at the cost of cobblestone-worthy comfort. It's a rare mix of race-bred endurance geometry for long-mile comfort, a high-modulus carbon lay-up for sprint-worthy stiffness, and an overall lightweight package that can soar--or at least not hold you back--on the climbs. The Fenix SL maintains that plush ride in a lighter, stiffer package than the previous Fenix thanks to a few design updates. These include narrower, flat-section seat stays that absorb power-sucking road noise while maintaining lateral stiffness. The stays feed into a seatpost that's reduced from the previous model's 31. 6mm to a more compliant 27. 2mm. The flat, curved top tube is another significant redesign, serving as a leaf spring of sorts that works in conjunction with the seatstays and slimmed-down seatpost to disperse bumps. The net result is a system-wide increase in vibration damping and compliance for a more forgiving ride across...
