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 11-32 cassette to help you on the toughest climbs.
RS805 full hydraulic brakes offer brilliant all weather braking with excellent modulation and pad retraction minimising brake rub.
P-SLR1 Wheels offer super low weight with carbon composite rims and excellent stiffness thanks to the Dynamic Balanced Load spoke pattern. P-SLR1 wheels are tubeless and supplied with Gavia tubeless tyres.
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.
This bicycle features an integrated seat post which requires cutting to suit the rider's required saddle height. Once cut, adjustment is still possible (typically 20-25mm). We recommend preforming this task for you in store.
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.

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.
