New bling for the whip – a White Industries “ENO UNO Trials” 18-tooth freewheel. White makes the strongest, most durable freewheels anywhere, elevating an often-overlooked yet crucial part of all single-speed bikes to an art form. The 1.370″ x 24 tpi threads fit standard freewheel hubs. It is fully serviceable and re-buildable. The Trials is their top model, made of nickle-plated case hardened 8620 steel and featuring a ratcheting mechanism with 72 teeth in which six pawls engage.  Most freewheels have just one or two pawls… the ratchet noise this thing makes is sickkkk!
I bought this one for my Fuji Track Pro to compliment its new Dura Ace 7600 / Velocity Deep-V wheelset. This is the only freewheel built with the kind of quality equal to its all-Dura Ace drivetrain. I got this one for $50 gently used on Ebay, but they are for sale at Ben’s Cycle for $110 new.
