Our founder Bob Parlee spent two decades working on fluid dynamics as a high-end boat designer before he began building road bikes in the 1990s. The result? Up to 75mm front-to-back adjustment, allowing a huge range from far-forward performance triathlon positioning (74-81 degree virtual seattube) to a UCI-legal TT position (5cm behind the spindle). The TTiR builds on that tradition, also adding a new adjustable seat rail system that’s inspired by the “Picatinny” design, a military precision bracket system. Combined with Parlee’s unique, multi-position seatpost, it gave riders new ways to achieve the perfect balance between aerodynamic efficiency and power-enhancing comfort. By offering 10 sizes (versus the typical 3 or 4), this system, which emphasizes comfort and fit, was the backbone of that first TT. Parlee’s original TT model changed the game when it introduced our vaunted Flex-Fit system to the triathlon/TT market. And new, all-internal cable routing is optimized for mechanical or electronic shifting including internal battery access and clean cable ports that are tucked away from the wind behind the stem. Other new updates with the TTiR include direct mount rear brakes that are lighter, perform better, and are compatible with the latest Shimano group sets. Plus, the new chainstays are handcrafted with compression molded vertical carbon dropouts and a replaceable derailleur hanger-making wheel changes much easier compared to the previous horizontal dropout design. The new BB/chainstay design also allows for today’s wider-rimmed disc and aero wheels. Tests on the new design show an increase of 10 to 12 percent in BB/chainstay stiffness-which helps maximize every last watt of pedaling power in your race against the clock. This new module not only reduces the frame weight by 50 grams, but it boosts stiffness in an area of the frame where you want it most. Among its most noticeable updates is its all-new chainstay and bottom bracket design. The TTiR is a third generation triathlon bike. We built our name on creating lightweight, high-performance carbon frames that, compared to off-the-shelf options from major manufacturers, fit like a glove and ride like a dream. The other part is the obsessive commitment to ride quality that defines the Parlee brand. Not only is the TTiR one of the lightest time trial/triathlon bikes in the world, but wind-tunnel tests show it to be one of the fastest and most efficient in a wide range of riding conditions.īut that’s just part of the story. When it comes to aero performance, the numbers don’t lie. Craftsmanship, aero engineering, athlete testing -each plays a role. It’s impossible to pinpoint one single factor that makes the TTiR so special. Like its predecessor, this new machine benefits from unique airfoil technologies paired with a ride quality, comfort and precision fit that no other time trial bike in the world can match. Building on the success of the TTi, the all-new TTiR represents the most advanced triathlon bike ever built by Parlee.
