Detailed Description for Ridley Fenix SL 105 Mix Red
The Fenix SL is Ridley's premier ‘all around’ bike. It offers a perfect balance between true race performance, proven strength, durability and all day ride comfort.
Ridley engineers took all the best of their previous Fenix, superlight Helium SL and aero Noah SL, and put it into the Fenix SL. The stiff and aerodynamic headtube, combined with the strong bottom bracket and the lightweight narrow seat stays do not only make it look good, but they make it fast as well.
Fenix SL frameset is built form a mix of 24T and 30T carbon fibre to make it stiff in critical areas like bottom bracket or head tube and compliant where it needs to absort vibrations from the road. It is designed to accommodate 28mm tyres to further increase comfort. BB86 bottom bracket standard is wider than in the previous version of Fenix and allows for beefier chain stays and clearance for bigger tyres. Diamond tube sectins of the frameset apart from ride quality, also offer improved impact ressistance, which is great news from durability point of veiw.
Fenix SL is a perfect bike for riders who appreciate the perfomace of a top-end racing frameset, but also require comfort and compliance from their bikes.
