Surly Track Sprockets (17-22T)

Surly Track Sprockets (17-22T)

This high-quality and durable sprocket is designed to spin onto standard ISO-threaded (1.375" x 24tpi) hubs, so it will work with most English, Italian and Japanese types, including the Surly New track hubs. Just like the cassette-splined cogs, this model is made from machined, heat treated and chrome plated SCM415 CrMo steel, making it tough and long-lasting. Track cogs are available in either 3/32" or 1/8" tooth thicknesses and in every size from 13T - 22T.

Features:

• Material: Precision CNC-machined CrMo Steel
• Speed: Single speed
• Wear resistant and hardened material
• 7.4mm wide thread base for maximum thread engagement
• ISO Threaded (1.375x24Tpi)
• 3/32" or 1/8" chain sizes available
