I am collecting parts to customise my Wabi Special from Wabi Cycles. This is a 17 tooth White Industries ENO freewheel. I could not justify spending $110 on a freewheel on my other cheap singlespeeds, Bumblebee and Wonder Woman; but I can on my beautiful Wabi Special that I have named Tigger. Thanks to Gear Shop Brisbane for supplying the freewheel.
My plan is to mate the 17 tooth freewheel with a 52 tooth chainring. The 52/17 combination will effectively give me the same gear ratio (80.4 gear inches) as using a 46/15 chainring/freewheel combination (80.6 gear inches). This is one tooth up on the 46/16 combination that I am currently riding. Freewheels generally only come in 16/17/18 teeth, so purchasing a 15 tooth freewheel was not an option.
For the record, the 17 tooth White Industries ENO freewheel weighs in at 174 grams on my wife’s kitchen scales.
