Product overview
The 4500 has been a best seller since its introduction in 1998. This year’s model retains its comfortable riding position, but packs in better spec for your money. Featuring a 27 speed Deore-based drivetrain, a Rockshox Dart 2 fork with lock-out, and a disc ready wheelset to allow for easy future upgrades. Another winner.
