The Giant Defy Advanced Pro 1 offers Shimano Ultegra components and a Giant Contact SLR composite handlebar as upgrades over the Defy Advanced Pro 2.

Updated for 2019, the Giant Defy Advanced Pro continues to be the class leading premium road endurance bike. Now with increased tyre clearance (up to 32mm), revised tube profiling and a D-Fuse handlebar the new Defy Advanced Pro maintains it excellent pedalling efficiency whilst compliance increases. With evolution comes more refinement and Defy Advanced Pro bikes feature premium paint finishes and the neatness of a cable and hose concealing Stealth stem. Advanced Pro models offer OverDrive2 fork steerer tubes, Carbon wheels systems and an included ANT RideSense sensor (sensor fitted upon request) as upgrades over the Defy Advanced range.

The key to the Defy Advanced Pro's success is the way in which Giant have sculpted their Advanced-grade composite frame with tube shapes and a carbon fibre layup that are optimised to absorb road shocks and vibrations in the right places whilst offering stiffness for power transfer in others. This profiling technology can also be seen in the D-Fuse handlebar and seatpost which allow flex in one plane for comfort whilst offering stability in the other plane for efficiency. Giant's Advanced grade composite is woven by Giant in their own facility which is unique for a bicycle manufacturer. This allows Giant to create a carbon fibre which meets their exact requirements rather than making do with what is available from a third party. This also means Giant can offer better grades of fibres at lower prices which is better for you!

The Defy Advanced Pro 1 comes complete with Giant's SLR 1 carbon wheelsystem with a 30mm deep carbon rim. Not only does the SLR1 wheelsystem offer low weight but the Dynamic Balanced Laced wheels offer a noticeably more responsive ride than traditionally laced wheels.

The Giant Defy Advanced Pro 1 features seamless disc brake integration including flat mounts and 12mm front and rear thru-axles producing more consistent braking power for better control, particularly in wet weather and on rough roads. Stopping power on the Defy Advanced Pro 1 is provided by Shimano's Ultegra hydraulic disc brakes which offer excellent feel, power and modulation in a lightweight package.

Another key feature found across the Defy Advanced Pro range which helps set it apart from the pack is the inclusion of tubeless tyres and wheels from the box. Tubeless road technology reduces rolling resistance and can help to reduce punctures too which are real performance benefits not normally found at this pricepoint. The tyres fitted to the Giant Defy Advanced Pro 1 are Giant's AC1 Tubeless tyres in 28mm which provide a great balance of puncture protection and performance.

The Defy Advanced Pro 1's drivetrain is courtesy of Shimano's legendary Ultegra components which offer low weight and excellent shift performance. Gearing covers a huge range with 50x34 at the front and 11x34 at the rear.

If you are looking for a great premium all round endurance road bike which offers all day comfort, sufficient suppleness for rough roads and excellent power transfer then Giant's Defy Advanced Pro 1 really does offer everything.

Please note: This model requires an additional assembly step when purchased for home delivery. Please follow the following steps to fit the stem cable and hose covers once the handlebar stem has been rotated and tightened. Shipping of the bicycle with these covers fitted is not possible.
Contact SL Stealth Stem

Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling. Should you wish for the bicycle to be supplied with inner tubes fitted rather being set up tubeless please contact us after placing your order.

IMPORTANT: This bicycle is supplied without pedals.
