Derailleur Pulleys

Shift Smoother and Save Energy

Directline Ceramic-Hybrid Derailleur Pulleys are designed and manufactured for maximum performance. Enduro pulleys are machined from 500 AF Delrin pulley material and feature CN (tight clearance) bearings in the upper pulley to maximize shifting accuracy and C4 (floating clearance) bearings in the lower pulley to allow for chain-line movement. An ideal material for the application, 500 AF Delrin pulley material machines very cleanly and precisely and features high mechanical tensile strength, rigidity, natural lubricity, high resistance to moisture, caustic chemicals and UV makes these pulleys highly durable, rigid and very smooth.  The inherent lubricative qualities of this Teflon-infused material greatly reduces friction when it interfaces with the bicycle chain. When compared to other pulley materials, 500 AF Delrin with Teflon, offers significantly less drag than pulleys machined from aluminum or titanium.

We proudly manufacture our pulleys in the USA for many models of SRAM, Shimano and Campagnolo derailleurs to precisely meet the manufacturer's specifications (non-oversized) to preserve the derailleur's designed functionality. While Enduro pulleys provide all of the power performance benefits claimed by other brands, they will also improve shifting precision and last for years. XD-15 pulleys are so robust that they are guaranteed against corrosion for life, and only get faster the more miles they see.
