Vivid Coil Ultimate DH D1 is RockShox's coil shock for downhill bikes, built for consistent, controllable damping on long, rough descents. This one is 225x72.5mm with a standard shaft eyelet and a trunnion body mount.

Highlights

• RC2 damper with independent low- and high-speed compression
• Numbered compression adjuster that starts from 0
• Adjustable Bottom Out: five settings acting on the last 20% of travel
• Removable rebound knob doubles as the HSC and bottom-out tool
• 20 clicks of rebound adjustment

Damping and spring

A coil spring gives a supple, consistent feel through the stroke. A new base valve reduces IFP force, and the main piston tunes are matched to RockShox's Charger 3.2 fork damper.

This configuration

Factory tune is rebound R55 and compression C34. It is eBike approved.

Compatibility and fit

Match the eye-to-eye length, stroke and eyelet/mount type to your frame maker's spec before ordering; trunnion mounts suit frames designed for them only. Choose a coil spring rated for your weight and this stroke. SRAM offers an 8x30 bearing adapter for standard eyelets, sold separately. Tune Cycles can fit and set up the shock.
