Cube Attain GTC SL Disc review

1 Mar 2018

A fast and comfortable ride with an excellent specification

Cyclist Rating: 
Great frame and parts gives a smooth ride • Low weight for climbing • Excellent Ultegra groupset
High front end • Cable rattle • Awkward rear axle nut

Looking at the spec sheet alone, the Cube puts itself a few steps ahead of many similarly priced rivals from the start, with a complete Shimano Ultegra R8000 groupset and no shortcuts, even for the cassette and chain.

The updated Ultegra groupset is fantastic, giving accurate, smooth shifting every time. Braking performance from the hydraulic callipers is also good, with enough power and modulation for all riders.

Ride quality shines through from the off, with both the front and rear giving a very smooth ride, with very little vibration coming back through the hands.

The Continental tyres come up a little wider than the claimed 28mm, which also helps with comfort, but without drowning out the road feel helping increase confidence on the downhills.

While our test bike was not fitted with mudguards, the Attain does have neat, hidden mounts and a bespoke pair of mudguards is available.

While they will probably add around 500g to the overall weight, it would still be an impressively light bike.

Endurance and comfort are key areas where Cube hopes the Attain will deliver, with geometry that achieves a slightly higher, more upright riding position which will suit the majority of riders.

Although Cube claims ‘Road Race Configuration’ – as written on the top tube – it doesn’t achieve this in reality, with its tall front end not really being designed for getting low and aero.

Cube should be applauded for touches such as the full-length outer cables, which should last significantly longer than exposed gear cables on bikes used year round.

Occasionally, the cable can be heard rattling inside the down tube, but a gentle pull to straighten it will keep it quiet for long enough.

A slight annoyance was the rear wheel axle nut and mech hanger combination.

Held in place by a tiny Philips-head bolt, it did not feel overly secure, although should an accident happen, it would be cheaper to replace a small aluminium part rather than break the carbon frame and in practice does little to detract from a comfortable yet fast and lively ride.



Frame 8/10; Components 9/10; Wheels 8/10; The ride 9/10

Verdict: Throughout the test the Attain exceeded our expectations. It delivers a fast, comfortable ride with a great groupset and general specification. While our test bike was not fitted with mudguards, it features neat mounts that would turn the Attain into a true four-season powerhouse.
