Wabi Cycles 18/16 Dual Fixed Cog
Custom CNC'ed 1 piece dual rear cog (18 and 16T) allows a gearing choice
without removing the rear wheel. Just loosen the axle nuts, slide the wheel
forward, move the chain to the other cog, set the chain tension and re-tighten
the rear axle nuts.

It's lighter than 2 separate cogs, and don't worry about alignment. It can only
be used with a 3/32" chain which has plenty of flexibility to handle a few mm
of lateral positioning.

Another nice feature is that it allows yet another option for the other side of
the hub, assuming it's a flip flop hub.

Supplied with its own lock ring.
