The Trek Roscoe hardtail trail bike sees big updates for the 2022 model year with new geometry and improved features. The best part is this newly more capable bike is affordably priced.
Starting at the front of the bike, the updated Roscoe features a slack 65° head angle and a reach that’s grown significantly, increasing 45mm or more on most sizes. The seat tube angle has been steepened as well, to 74.7°, which might not sound all that dramatic to full-suspension riders but it’s up there for bikes with rigid rear ends. The bikes feature a straight top tube and Trek says there’s still plenty of standover clearance on all sizes thanks to the longer reaches. Also notable is the lack of a Knock Block.
As you can see from the geometry chart below, all frame sizes except extra small are designed for 29er wheels.
