Surly Track Hub Set 32h 100/120mm Fix/Free pre-laced

All Surly Hubs are forged aluminum with medium height flanges, and spin on high load, well sealed, adjustable cartridge bearings over standard sized axles (9x1mm front, 10x1mm rear). This is a common size so it’s easy to find replacements should the need arise or to swap axles if, for instance, you have a QR axle and want to go solid. And did you notice we said the bearings are adjustable? This is so you can adjust play as the bearings wear so you don’t have to replace bearings as often.
