Parlee Altum Road Frameset
The lightest model in the Altum series; the Altum Road Frameset starts with Parlee's highest modulus carbon fibre material. Through a combination of complex FEA (Finite Element Analysis) modelling and physical testing, Parlee engineered a new layup process that places the high modulus carbon fibre in strategic areas to maximise weight reduction without negatively impacting strength or stiffness.
One look at the new frame design reveals more pronounced tube shaping and transitions than those of the Altum’s Z series predecessors. The top tube and head tube flare out where they meet, as does the seat tube and downtube at the bottom bracket area. The result: a super-light frameset with increased steering stiffness and pedalling efficiency.
Of course, it’s not just about stiffness and weight. Much of the carbon layup strategy is based on Parlee’s goal of attaining a certain ride quality. The Altum is engineered to feel responsive when you stand up and sprint but have just enough compliance, especially in the rear triangle, to give it a smooth ride quality. All of the Altum models use a traditional round 31.6mm seatpost with a hidden, integrated binder, and they've introducing a new specially designed composite post that weighs just 185 grams and adds road-smoothing compliance.
Other new features include increased tyre clearance, from 23c to 28c, and a new fork design with an integrated carbon crown that helps increase stiffness while shaving 20 grams compared to Z5 SLi model fork. The internal cable routing is compatible with all major groupsets, both electronic and mechanical, and has been designed to make installation and service as simple as possible.
