Fast steering is great for aspiring racers, but less confident riders will find it hard work to keep it under control

At the heart of the Wilier GTR SL is an impressively lightweight frame, which at a claimed 990g just nips under the magic 1kg mark.

The low weight is carried through to the full bike, feeling impressively light on both the unscientific lift test and also on the scales.

The ride is agile and fast, which became apparent as soon as we climbed aboard and hit the road.

In fact, such is its liveliness and propensity to change direction at lightning speed that it took us a little while to get tuned in to it.

Acceleration is also impressive, being efficient when pedalling and especially on the climbs where the low weight is noticeable.

Downhill, the GTR SL can be a handful at times, with the quick steering making it agile but can also feel a little nervous at speed, and it takes a while for confidence to build but the eagerness to turn is something that budding racers will love.

The wheels are without a doubt a stand-out feature, with the Mavic Cosmic Pro carbon rims that not only look the part but are stiff and fast thanks to the deep section.

They are also surprisingly good in cross winds and big bonus for typical British riding conditions is the aluminium Exalith braking surface, which gives predictable and powerful stopping in all weathers, while their matching Yksion Pro tyres are suitably fast rolling.

The Shimano Ultegra groupset is fantastic and impossible to fault with smooth shifting at all times, and helping to keep the weight down.

The FSA finishing kit does the job with good all-round performance. We particularly liked the handlebars with their comfortable ovalised shape.

Ride comfort when seated is impressive, especially at the rear end thanks in part to the pencil-thin carbon-fibre seatstays and the comfortable Selle San Marco saddle.

However, there is some feedback and buzz that comes through the fork at the front end, giving a little imbalance to the ride feel overall, but if you want a lively, responsive ride, this bike is a winner.

Once we got to grips with its lively nature, we found it an exciting and rewarding ride.

Ratings

Frame 9/10; Components 9/10; Wheels 9/10; The Ride: 9/10

Verdict: The Wilier feels incredibly fast, light and agile and is an impressive climber in part thanks to the low overall weight. The deep-section Mavic wheels help the bike look the part but offer a good overall performance.  Racers and those who love climbing will love its sheer grin-inducing speed.
