the disc brakes are just lightyears ahead of cantilevers

Exclusive: Trek Boone 9 Disc first ride review

Jan 2014 · James Huang

Not surprisingly, the Boone also has similar frame features, including an extra-wide BB90 bottom bracket shell and tapered ‘e2’ 1 1/8-to-1 1/2in head tube – both with drop-in bearings – Trek’s usual no-cut integrated seatmast, and convertible internal routing that can be used with either mechanical or electronic drivetrains. . .
