New for 2018, the Giant Propel Advanced SL 1 Disc takes the proven Propel platform and uses the advances is road bike disc brake technology to further enhance its aerodynamic performance. By removing the traditional rim brake calipers from the Propel's frame the airflow around critical areas of the bike has been improved further reducing aero drag. When compared to rim brakes, the compact disc brake calipers have much less of an effect on airflow but bring the benefits of better all weather braking and vastly improved brake modulation. The Propel Advanced SL 1 Disc also benefits from a new integrated handlebar design which fully encloses the handlebar cable routing which helps tidy airflow around an important aerodynamic area.

Giant's Propel Advanced SL Disc bikes use Giant's highest grade of carbon fibre and the very best manufacturing techniques to create a frame and fork which is lighter, stiffer and more compliant than the Advanced Pro models. Advanced SL models feature an integrated seatpost design which we will cut to your required saddle height. This design offers less weight and more seatpost flex than a standard seatpost which aids comfort on the road.

The Propel Advanced SL 1 Disc's componentry is based around Shimano's all new Ultegra Di2 electronic 22 speed groupset which has been revised for 2018 offering many developments from the Dura Ace groupset and revised ergonomics. Shimano's Di2 electronic shifting is renowned for its precision and reliable performance over time giving the rider the ultimate shifting experience. The Propel Advanced SL 1 Disc is fitted with an 11-28 cassette and a semi compact 52-36 chainset to give you a great spread of gearing for fast flat riding and steeper climbs too. 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.

The Giant Propel Advanced SL 1 Disc models come complete with SLR1 Aero Disc wheelsystem with a full carbon deep section rim to minimise drag and weight whilst Dynamic Balanced Load spoking maximizes wheel response and durability. Rim depths are split 42/65mm Front/Rear to get the best balance of aero performance and control. The rims of the SLR1 Aero Disc wheels are a tubeless design and tubeless tyres come pre installed. Not only does this offer a superior ride quality but also helps to minimise punctures.

The all new Giant Propel Advanced SL 1 Disc is the perfect tool for the rider who wants to use the very latest in bicycle technology and design to make them faster. With a race fit, the Propel Advanced Disc is ideal for races, triathlons or just going plain fast.

Please note: 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.
