Transition’s latest 29er, the Sentinel, has been built around the brand’s new ‘Speed Balance Geometry’ concept (SBG). Similar to what we’ve seen from Mojo’s Chris Porter, that means it gets a longer reach (450mm, medium), slacker head angle (64 degrees – even more extreme than that of Mojo’s GeoMetron G13 29er), steeper seat angle (76.8 degrees) and shorter fork offset (43mm) than other bikes in its class. According to Transition, these elements combine to make the 140mmtravel Sentinel climb more effectively, feel more stable and capable at speed, and deliver more traction between the tyres and trail when it counts most. We can’t wait to sling a leg over one.
