Giant's Defy Advanced Pro 1 offers Shimano's all new Ultegra drivetrain components as upgrades over the Defy Advanced Pro 2.
Giant's Defy Advanced Pro 1 uses Advanced grade composite and has a full composite Overdrive 2 fork. The addition of the full composite Overdrive 2 fork on Advanced Pro models not only reduces weight but improves steering stiffness and power transfer through the handlebars whilst super thin seat stays and a D-Fuse composite seatpost gives excellent vertical compliance at the rear. The Defy Advanced Pro's acclaimed geometry gives an efficient, comfortable and sporting riding position which suits almost all body shapes. Like all other Advanced Pro models the Defy Advanced Pro 1 comes complete with a Giant RideSense ANT+ sensor (sensor fitted upon request).
The Defy Advanced Pro 1's componentry is based on Shimano's all new Ultegra 22 speed groupset which has been revised for 2018 offering many developments from the Dura Ace groupset and revised ergonomics. The Defy Advanced Pro 1 is fitted with an 11-34 cassette and a compact 50-34 chainset to give you a great spread of gearing which is suitable for the steepest of climbs. Stopping power is provided courtesy of Shimano's all new Ultegra hydraulic disc brakes which offer excellent all weather performance, precise modulation and upgraded ergonomics.
Giant's SLR 1 disc wheel system offers a full carbon rim laced into the hub using Dynamic Balanced Lacing spokes which maximize responsiveness and durability. The SLR1's rims are a tubeless design and used in conjunction with the Gavia AC tubeless tyres offer a superior ride quality and puncture protection over a traditional inner tube setup.
The Defy Advanced Pro 1 is perfect for riders looking for high end endurance bike performance with a smooth yet responsive ride for all types of roads. With excellent all weather control and a great componentry specification the Defy Advanced Pro 1 is versatile, fast and fun.
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.
