Verdict: Engaging and versatile disc-ready frameset that’ll take rim brakes too.
The Kinesis Racelight 4S Disc is the disc-ready evolution of Kinesis’ winter platform. 4S stands for Four Seasons and this is certainly a frameset that’s capable enough for building up and riding at any point during the year.
There’s nothing it likes better than kicking off in response to a big jump on the pedals, and the big downtube and beefy stays make for excellent power transfer with no hint of flex.
I took the 4S Disc on long training rides, commuted to work on it, did sprint intervals on it and even rode it round muddy reservoir trails in the dark, and it was happy enough doing any of that.

For a bike to be ridden through the vagaries of British weather, the 4S Disc frame and its build kit make a lot of sense. There’s enough clearance to use wider tyres and still fit mudguards.
With quite a short head tube, the bike’s stack is low. This wasn’t uncomfortable though and made for a feel much more like a bike designed for racing than an endurance machine. For a winter machine, this seems like an attractive proposition, meaning that you will not have to adjust your position too much from that which you would have on your summer bike.

VERDICT: A superb British-designed, disc-ready all-rounder.
Designed for typically wet and variable UK riding conditions, the Kinesis Racelight 4S – which stands for ‘four seasons’ – promises to be a year-round ride for all your training and racing needs.
When climbing or sprinting the 4S responds well, with little noticeable flex in the frame or wheels and although the overall weight is on the bulky side thanks to those disc brakes, it never felt slow or hard work on longer rides.

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.
