Description
Upgrade your frameset for a lightweight racing machine that delivers in rigid performance, speed and stability. The Kinesis Racelight Aithein Evo Frameset proves to be an agile racing frame, fit for leisure weekend rides or competing for the top spot in local criterium races.
Kinesis international have dedicated their time to manufacturing an aluminium frame that is incredibly respondent and rigid, thanks to the implementation of their Kinesium aluminium and unique Super-Plastic Formed (SPF) seat tube.
Super-Plastic Forming results in lightweight tubing versatile enough to form accurate and specific shapes, which allowed Kinesis to design a unique seat tube with a wider bottom bracket shell to reduce flex and maximise power output, perfect for high-speed sprints. The particular shape of the Antigravity seat tube additionally increases the core strength of the frame, achieving less torsional strain within the main frame tubing, enabling the use of lightweight Kinesium aluminium that boasts to be 25% stronger than 6061 aluminium.
Achieving precision control, the featured angular contact bearings sit within a larger crown for reduced braking flex, whilst slackening the head tube angle for sharper responses and control. With carbon forks, this frame slices through the air and powers through races with less flex, and increasingly compliant performance.
The increased tyre clearance means you can now fit 28mm tyres onto this stylish racing machine, so you can experience the benefits of increased traction and greater comfort throughout your leisure rides or races.
Finessed with style, this laser-etched decal frame features internal cable routing for a cleaner appearance. With an anodised finish, this incredibly efficient alloy frame will have heads turning.
