Product Description
The RockShox Deluxe Ultimate 205 x 50mm Rear Shock is a high-performance air rear shock built for lightweight, capable mountain bikes that need efficient pedaling, strong traction control, and a smooth ride feel. This B2 series shock uses a fully checked damper with low speed compression adjustment and separate open and threshold pistons for more precise tuning on the trail. The DebonAir™ spring helps deliver a smooth, consistent feel through the travel, while Maxima Plush damping fluid reduces friction and helps quiet damper noise. This version features a 205x50 trunnion mount, black on black finish, and comes in retail packaging.
