Wilier Triestina Granturismo SL Disc Shimano 105 Di2 R7170 + Miche Swr 40 bike 2025

Long-distance comfort, SLR performance

The Granturismo endurance range expands with the introduction of the SL version, designed to bring the quality and riding performance of the flagship SLR model to the general public, while adding a touch of novelty when it comes to the tyre transition.
The Granturismo SL allows you to tackle long distances with greater comfort. The high quality materials and technologies used in the construction of the frame guarantee a damping of stresses in the vertical plane, while maintaining its responsiveness.
When using single-crown groupsets, the front derailleur attachment can be removed, transforming the Granturismo SL into a bike with even cleaner and more modern lines.

SL philosophy for an endurance bike for everyone
This model represents the perfect balance between innovation, comfort and convenience, confirming once again Wilier's commitment to making its state-of-the-art bicycles accessible to all cycling enthusiasts.

UDH® dropout and carbon seatpost
The rear dropout is of the UDH® type and the carbon seatpost has an aerodynamic profile.

Tyre passage
The tyre passage is generous, allowing the installation of tyres up to 38mm wide, making it a full-fledged allroad bike.
