It's constructed from a durable, reliable, and lightweight A1 SL Premium Aluminium, and it features a bombproof assortment of components, like a Shimano Sora rear derailleur and powerful Tektro hydraulic disc brakes that are sure to get the job done.
Sprinkle in some added comfort from the proven Body Geometry components, like the grips and saddle, and a Fitness geometry that lives in the sweet spot between comfort and performance, and you have a bike that'll always be ready to go when it comes time to sweat.
- Working with Specialized's Body Geometry team, they designed a frame that strikes the optimal balance between comfort and efficiency. The A1 SL Premium Aluminium construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
- The lightweight FACT carbon fibre fork provides a smooth, responsive ride, while the Plug + Play fender mounts give you the option to install rain-fighting fenders.
- Braking duties are handled by Tektro hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.
