Giant has launched a new Defy endurance bike, which it says is engineered for better road-smoothing comfort and greater integration than ever before. The Taiwanese firm's latest machine comes with an all-new handlebar, borrowing comfort-enhancing technology previously found on the Defy's seatpost, while the flagship bike features Giant's new power meter. 

At the heart of the model year 2019 Defy is an all-new carbon frameset that features a front triangle moulded into one continuous piece, said to give a more consistent level of comfort, while still producing a stiff ride. The key for Giant, when revamping the Defy, was to retain the platform's endurance-focused design and versatility, while still ensuring this is a bike capable of mixing it when the pace hots up.

Compliance-led frame tech and a new handlebar

The Defy's carbon frame is based around what Giant calls 'Compliance Tuned Technology' to help keep the ride smooth. It says specific carbon layups and tube profiles have been used strategically throughout the frameset, along with narrow, flattened seatstays and forward-curving fork legs to maximise compliance, and a low seatstay-seattube junction that has become the norm in recent years among bikes prioritising a smooth ride.

Giant's road-buzz reducing 'D-Fuse' carbon seatpost, previously seen on the old Defy, is also present and comes with claims of 12mm of possible flex to help keep things comfy through the rear end of the bike.

More significantly, as far as the latest Defy is concerned, there's also a brand new handlebar design. Giant has implemented the D-Fuse design into the new Contact SLR (carbon) and SL (aluminium) handlebars, with a D-shaped design said to offer up to ten per cent more compliance with downward pressure and thirty per cent more stiffness when pulled for the latter. Those are impressive claims and the new cockpit also has the added benefit of keeping the front-end cable-free.

Otherwise, Giant led the way when it comes to compact frame geometry and the philosophy continues to be applied to the Defy. “A downward sloping toptube creates smaller front and rear triangles for a lighter, stiffer bike," according to Giant. "It also makes it easier for riders of all sizes to have a perfect fit.”

The Defy framesets – available at Advanced Pro and Advanced levels, with differing carbon layups – feature full internal cable routing, are disc brake-only, and support the usual refinements of 12mm thru-axles and flat-mount brake calipers. In the chainstays, an integrated RideSense transmitter in the Advanced Pro models can send wheel speed and cadence data to your Bluetooth-enabled head unit, while the Giant’s Power Pro power meter appears on the top-level Advanced Pro 0 build.

“With multi-axis left and right crank arm sensors, it pairs with the Giant NeosTrack GPS computer to display vital information including power (watts), pedal balance, force angle and cadence,” says Giant of the power meter, which is also compatible with other ANT+ and Bluetooth-compatible computers.

Importantly, given the Defy's versatile aspirations, the new frameset offers increased tyre clearance over the old model, with space for up to 32mm tyres, while you'll also find integrated mudguard eyelets. All bikes will be supplied with varying models of Giant’s own tubeless ‘wheelsystems’ with Gavia AC 1 28c rubber - check out the full spec details in the boxout. UK prices are to be confirmed.
