How do we rank
Our AI-powered platform ranks products using multiple weighted factors from millions of products and user reviews across the web, providing the most valuable and real data. Higher scores rank first.
ULTRALIGHT AND RESISTANT: CNC machined with aluminum alloy that ensures maximum strength and durability with the least weight (Ultralight 10g) and a perfect finish. The MTB jockey wheels are anodized in 5 different colors (black, red, blue, gold and silver) to prevent rust and corrosion
IMPROVES PEDALING SPEED BY REDUCING FRICTION: The ceramic inner bearing, specially designed for cycling, has minimal friction that significantly improves performance thanks to a much smoother transmission

Hybrid Ceramic bearings to lessen friction and packed with grease for flawless use all year round!
Low friction bearings- Each derailleur pulley wheel includes a hybrid ceramic bearing lubricated with an additional coating of grease and protective dust caps for longevity, higher load tolerance, and lessened frictioned when compared to steel bearings
Lightweight Design - Each pair of 13-teeth Ceramic Pulley wheels weigh only 24g. The lightweight design paired with the strong 7075 billet aluminum used to manufacture them gives our pulleys a higher strength-to-weight ratio and flawless shifting properties
Compatible with all Shimano 12 Speed MTB Rear Derailleurs - The JRC Components Hybrid Ceramic Pulley Wheels feature low friction bearings and crisp shifting making them the perfect upgrade for your Shimano MTB System
ULTRA-LIGHT CNC 7075 ALUMINIUM CONSTRUCTION Precision-machined from high-strength CNC 7075 aluminium, weighing only 10 g (12T Guide) and 11.5 g (14T Tension). These MTB derailleur jockey wheels are exceptionally strong yet lightweight, offering outstanding durability without adding extra weight. Ideal for MTB, gravel or road bikes.
SMOOTHER, LOW-NOISE AND MORE PRECISE SHIFTING The 12T and 14T jockey wheels with narrow-wide tooth profile improve chain retention, reduce skipping, eliminate noise and deliver smooth shifting even on technical terrain. Perfect for demanding riders seeking real efficiency and professional performance.
SEALED SILICON NITRIDE CERAMIC BEARING Sealed ceramic pulley bearings made from silicon nitride – lighter, harder and more efficient than steel. They reduce friction, resist extreme wear and last longer than standard derailleur pulleys. The seal protects against dust, dirt, water and corrosion for smooth, durable performance in any conditions.
