The TMX is the flagship of the Brooklyn line of bikes. The frame is made from tig-welded 4130 chro-moly steel and features 10.5" of fully-active rear travel, an adjustable head tube angle, super-strong gussets, and classic brooklyn strength. The rear travel and shock rate are both adjustable. The TMX features a dual chain Independent Drive System. This creates a drivetrain that prevents induced shock compression
