BKCJ-0452 - 11 tooth, XD-15 Ceramic Hybrid Bearing, Machined Delrin Derailleur Pulleys for 12 speed Shimano Dura Ace Derailleurs (5mm bolt hole) - 

The ultimate upgrade pulley. Guaranteed to last forever against corrosion

Precision machined Delrin Derailleur pulleys featuring XD-15 Ceramic-Hybrid, radial bearings for enhanced shifting performance and longevity. Designed and manufactured for performance, these pulleys feature CN (tight clearance) bearings in the upper pulley to maximize shifting accuracy and C4 (loose clearance) bearings in the lower pulley to allow for chain-line movement.

500 AF Delrin pulley material features a high mechanical tensile strength and rigidity, natural lubricity, high resistance to moisture, caustic chemicals and UV makes these pulleys highly durable, rigid and very smooth. Delrin also machines very cleanly and precisely. 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.

An Enduro Bearings exclusive, our XD-15 Ceramic-Hybrid bearings combine corrosion-proof, cryogenically treated nitrogen steel races with Silicon Nitride grade 5 ceramic balls in a proprietary process that results in the ultimate high performance bearing setup. The deep-groove design raceways allow for maximum sized grade 5 Silicon Nitride ceramic balls for increased contact area and improved performance and longevity. 90% fill Kluber NBU52 grease only runs better and smoother with time and is highly resistant to being washed out. It is engineered to stick to the balls and continually be pulled back into the ball path where it is needed.

The eleven tooth upper and lower pulleys with 5mm bolt-holes are designed as a direct upgrade for 12 speed Dura Ace Shimano derailleurs.

Enduro Derailleur Pulleys are available in a number of configurations and performance levels, starting with Ceramic-Hybrid, Black-Oxide treated Zero Ceramic as a step up, and XD-15 Ceramic-Hybrid at the top of the line. All are proudly precision manufactured in the USA.

Loved it!
Color: Black, Size: 15.7"
These floating bathroom shelves are exactly what I was looking for. They’re sturdy, well-made, and look really nice once mounted. Installation was straightforward, and all the necessary hardware was included. The shelves hold a good amount of weight and are perfect for organizing bathroom essentials without taking up floor space. They add a modern, clean look to my bathroom and make it feel more organized. Great quality for the price — I’d definitely recommend these to anyone needing extra storage.

Easy install
Color: Black, Size: 15.7", Color: Black, Size: 15.7"
w I recently installed these bathroom shelves, and they completely exceeded my expectations. The quality feels solid and durable, and once mounted, they sit perfectly level without any wobble. I love how clean and modern they look — they instantly elevated the whole feel of the bathroom. The shelving space is surprisingly generous. I’m able to store everything from toiletries to décor pieces without the shelves feeling cluttered or overloaded. The finish also holds up well in humidity, which is a big deal for a bathroom environment. Installation was straightforward, the hardware included worked perfectly, and the shelves feel like they’re built to last. Overall, these shelves deliver both style and function, and I’m extremely pleased with how they turned out. Highly recommended if you want a simple upgrade that makes a big impact.
