Expert XD Single Speed Kit

Reverse Expert XD Single Speed Kit converts an XD driver into a single speed setup built for the chain management demands of gravity and full-suspension bikes. The kit pairs a refined-tooth single speed cog with CNC-machined aluminum sprocket guides that “sandwich” the chain at the rear cog, improving retention when the trail gets rough and conditions get messy.

• XD driver single speed conversion - Purpose-designed components simplify the move from cassette to single cog without improvised spacers
• Refined tooth profile - More secure chain engagement than traditional single speed cogs for fewer slip-related issues under load
• CNC aluminum sprocket guides - Acts like a rear-cog chain guide to stabilize the chain in high-impact riding
• Mud-shedding machining - Guide pattern helps clear dirt and debris to maintain function across changing trail conditions
• Complete kit hardware - Includes cog, alloy lockring, and two sprocket guides for a streamlined install
• Chainline requirement - Must be used with the Reverse Expert Colab Tensioner to ensure chainline compatibility
