Sterrata Disc Road Bike - 40c Tires

The Sterrata offers rugged durability, versatility, and makes an excellent commuting bike.  The frame is rack ready for commuting and touring use, while the carbon fork adds comfort and weight savings to your ride.  Avid BB5 disc brakes offer increased breaking power in tough conditions, while the full Shimano Claris drivetrain shifts smoothly through a wide variety of gears covering all possible trail conditions.




A Tommaso 6061 SLA Aluminum compact road frame and HCT Carbon fork make for a strong, reliable, and lightweight ride.  The frame is also rack ready for all your touring and commuting needs.



A full Shimano Claris groupset offers 24 quick, reliable speeds.  Using the full groupset ensures maximum performance, as all working parts were specifically designed to work flawlessly with one another.  This wide gearing ratio makes this bike perfect for climbing dirt and gravel trails, as well as commuting to work or play.



Heavy duty Tommaso Corsa TC-30D wheels are tough and aerodynamic.  These wheels specifically designed to handle rough terrain, dirt, and gravel.  The 28 spoke rims roll great and can handle the extra weight of touring gear with ease.
