Equipped with a SRAM 70 Eagle T-Type 12-speed drivetrain and reliable SRAM DB8 brakes, this bike doesn’t hold back when the going gets steep and rough. Tough Reserve 30|TR AL rims combined with legendary Maxxis Assegai and Minion DHR II tires offer confident control across every trail feature. The SDG Tellis dropper post, Burgtec or e13 cockpit, and robust components ensure the Bronson 70 is ready for rowdy rides right out of the box.
