Offering true value for money, the Alivio rear derailleur offers crisp performance on- and off-road for 9-speed drivetrains. Ideal for mountain biking or commuting, thanks to its tough, yet lightweight aluminium construction, the Alivio read mech sets the standard for performance at this price point. The clever 'shadow' design with smooth skid plate surface features a super low profile design that reduces the risk of damage from trail side hazards. The lightweight action of the RR MECH Alivio M4000 SW 9s SGS will make you think that you have a far more expensive derailleur taking care of your rear shifting.
