For SHIMANO freehub
The single-speed kit from Surly bikes.
Surly offers a single-speed spacer kit that allows you to use single-speed cassette cogs on the freehub body of your multi-speed Shimano cassette-compatible hub.
With the supplied selection of anodized aluminum spacers, you can attain a perfect chainline to compliment your road, track, or mountain crankset. Our large-diameter stainless steel cassette lockring holds everything together and perfectly matches the outside diameter of the spacers.
