Dual Fixed Cog 18/16

CNC machined 1-piece dual rear cog (18T and 16T) allows a gearing choice without removing the rear wheel. Just loosen the axle nuts, slide the wheel, 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.

Dual fixed cog works great

Great quality

The dual fixed cog was out of stock for a while so when I saw you had them back in stock I ordered one immediately. I wasn't disappointed, it's obviously a quality product the service was great. Now I have no excuse not to ride my Fixie up the longer steeper hills. Thanks Wabi...

Works great

I like the dual sprocket a lot. I ride in the 16 cog most of the time, but I have the 18 as an insurance policy of I get tired or come up against a big set of hills. The fit in finish on this cog is fantastic. Very well made.
