Giant's Defy Advanced SL platform offers the ultimate in endurance bike performance, a responsive ride and a disc brake specific design. Advanced SL models use Advanced SL composite as the main frame material and a full Advanced SL carbon Overdrive 2 fork. Advanced SL Composite is Giant's highest grade of composite and offers the very best in stiffness to weight ratio. Super thin seat stays and an integrated D-Fuse seatmast gives excellent vertical compliance at the rear whilst the Overdrive 2 fork steerer maximises front steering accuracy. Advanced SL models also feature Giant wheelsystems and an integrated RideSense ANT+ Speed/Cadence sensor.
The Defy Advanced Pro 1 SL's componentry is based around Shimano's Ultegra 22 speed groupset which is functionally superb and extremely lightweight too. The Defy Advanced Pro 1 SL is fitted with an 11-28 cassette to help you on the toughest climbs.
RS785 full hydraulic brakes offer brilliant all weather braking with excellent modulation and pad retraction minimising brake rub.
P-SLR0 Wheels offer super low weight with carbon composite rims and excellent stiffness thanks to the Dynamic Balanced Load spoke pattern. P-SLR0 Wheels are tubeless ready should you wish to take advantage of this technology at a later date.
The Defy Advanced SL1 offers the very best in frame technology for the rider who values efficiency, comfort and performance for all day rides or endurance events.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicyles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and resposibility on which size to purchase is your's.
