Specialized Amira SL4 Sport Womens Road Bike 2018
The Amira SL4 Sport Womens Road Bike 2018 is a do it all carbon road bike, equally as comfortable climbing mountains as it is sprinting away from the bunch in a race. The FACT 9r carbon fibre is extremely stiff and lightweight, providing a responsive ride, ideal for confident fast paced riding and climbing alike. The geometry has been designed specifically for women and is perfectly balanced to maintain its high level of performance across the size spectrum.
The high quality specification pairs well with the carbon frameset, ensuring the bike feels balanced and performs faultlessly in all situations. Shimano's 11-speed 105 5800 groupset provides crisp, predictable shifting, allowing you to get up to your desired speed and cadence without hesitation. Additionally, the DT Swiss R460 wheelset paired with Espoir Elite tyres, reduces rolling resistance and increases grip; a perfect combination for carrying your speed around a twisty, undulating course.
Features
- Specialized FACT 9r carbon, women's carbon layup and Competitive Geometry for speed and comfort
- FACT carbon fork soaks up road vibrations for a more efficient and comfortable ride
- Tektro Axis caliper rim brakes provide confidence and reliability on the descents
- Shimano 105 5800, 11-speed gearing continues efficiencies and keeps you spinning up tough gradients
