4S

£550.00

Practicality and Comfort without compromising on performance.
The Kinesis 4S is a bike you’ll want to ride whatever the weather.

*Build Kit options available.

Using our own, smooth welded ‘Kinesium’ tubeset and with clearance for full ‘guards, 28′s and long-drop brakes.

‘TRACER 1.5′ FORK: This fork, combined with the new taper head tube, transforms the handling and braking.

Rack mounts and ample clearance for full size ‘guards and up to 28c tyres [long reach, 47/57mm brakes required].

• Seat Post: 27.2mm
• Seat Clamp: 31.8mm
• Front Mech: 31.8mm
• BB: 68mm - British
• Headset: Integrated, 41.8ø upper, 51.8ø lower, for taper head tube
• Black and Blue or Silver and Orange.
Sizes: 48cm- 51cm – 54cm - 57cm – 60cm – 63cm

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. Included.

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.

Cycling Active

British brand Kinesis has built a reputation over its 10 years in the business for no-nonsense quality, top value and, above all, good design.

Clearly Kinesis seems to actually understand the sort of bike British riders want…the 4S frame, which is technologically superior to the three steel frames in this test and delivers the fast, classy ride of a bike twice its price…

Kinesis is going hard for a price point that is not significantly over £1,000 with the 4S, and with it being the lightest, the most race specific and the cheapest on test, it’s still a bargain.




The aim of the 4S is to provide a bike that will be worthy of use throughout the four seasons and it has undeniably succeeded.

The frame feels responsive, agile, punchy, when it needs to be, but these qualities are offset with equal amounts of comfort - enhancing characteristics and that is a difficult marriage to make.

A winter bike must be comfortable and hard wearing, but it mustn't let you forget you're a road cyclist, and the Kinesis 4S treads this line admirably.
