Kinesis Racelight 4S Frameset - Steel Silver


Out of Stock


The Racelight 4S framesets represent 12 years of steady evolution, built on feedback from hundreds of happy customers and direct consultation with team riders over the years. The new frame is offered with matched forks rather than frame only and uses very high quality forks to deliver a unique performance.

For 2014 Kinesis have treated this unique frameset to a totally new finish, bringing it into line with the latest frames and underlining it’s all-year capabilities by re-naming it ‘4S’, meaning ‘4 Season’. Using their own, smooth welded ‘Kinesium’ tubeset and with clearance for full guards, 28′s and long-drop brakes, this frameset makes a fantastic and well proven basis for a true 4-season bike. The 4S is a staple product for the committed racer during the winter months.

There is no other fork like the Tracer 1.5 available. This fork, combined with the new taper head tube, transforms the handling and braking of the Racelight 4S and brings it totally into line with your modern, summer season race bike. The gentle inward curve of the fork blades matches the ‘hourglass’ profile of the rear stays, helping to add comfort and tune out vibration.

The top tube is ‘power bulged’ at the headtube for maximum stiffness and the oversize, thin-wall down tube is aero section at the top and ovalised where it meets the BB for maximum weld area and response. The ‘anti-roadshock’ seatstays give maximum comfort for long training rides and the oversize chainstays and large downtube area at the BB keep power loss to a minimum.

Key Features:

  • 4 season frame
  • Smooth welded Kinesium tubeset
  • Clearance for full guards, 28's and long-drop brakes
  • Tracer 1.5 fork transforms the handling and braking of the Racelight 4S frame
  • Top tube is 'power bulged' at the headtube for maximum stiffness
  • 'Anti-roadshock' seatstays for maximum comfort on long training rides
  • Oversize chainstays and large downtube area at the BB keep power loss at a minimum

Technical Specifications:

  • Seatpost: 27.2mm.
  • Seat Clamp: 31.8mm.
  • Front mech: 31.8.
  • BB: 68mm. British.
  • Headset: Integrated, 41.8 upper, 51.8 lower, for taper head tube. FSA No.42/ACB headset included with frame. Both bearings are 'ACB', meaning 'Angular Contact Bearings'. The head-tube seat angle is 45º. The headset drops into a tapered seat in the head tube and is tensioned using a headset tensioner within the fork steerer. Tensioning the headset centres it on the taper and prevents any play. The larger lower bearing allows a tapered steerer and larger crown. This gives sharper response and helps reduce flex under braking.
  • Fork Recommendation: 'Tracer 1.5' Full monocoque, Unidirectional [UD] carbon fork with mudguard eyelets, clearance for full size mudguards and 28c tyres.
  • Kinesium: Developed by Kinesis International, Kinesium is a superb tubing for use in lightweight, high performance frames. Kinesium is enhanced 6000 series Aluminium alloy, which is 25% stronger than 6061 at the same weight level.
  • Power Bulge: ‘Power Bulged’ top tubes and seat tubes give maximum area at the head tube and BB for ultimate stiffness and response.
  • Ultra Smooth Weld Profile: This frame is joined using Kinesis developed smooth weld technology, giving tough, stress-free welds and clean appearance. The welding technique performed without secondary finishing or sanding, so weld bead and tube are left at full strength.
  • Tuned Stays: The 'anti-roadshock', 'hourglass' bend, seat stays are butted and shaped to give maximum comfort for long hours in the saddle.
