AITA Ceramic 13/15T Titanium Pulley Wheels - Campagnolo 11/12 Speed Road

Material Comparison:
Delrin – Durable, lightweight, and quiet; an affordable, no-frills option.
Carbon Fiber – Ultra-light and stylish but slightly noisier and less durable.
Alloy – Long-lasting with a mild noise increase over Delrin, offering a sleek look.
Titanium – Premium durability, lightweight, and visually striking but at a higher cost.
 

Tooth Count & Compatibility:

11T (Diameter: 42mm) – Fits most systems (short, medium, and long cage).
12T (Diameter: 46mm) & 13T (Diameter: 51mm) & 15T (Diameter:59mm) – Suitable for medium and long cages.
