Origin8 Ultim8 Single Speed Cassette Cog w/ 6b Disc Mount, 3/32", Black/Red

Together with a single speed conversion kit, this Single Speed Cassette Cog looks really handsome on my bike. I hope that this setup will SAVE me a lot of energy from constant gear shifting and my wrists. Will see...2/9/20 Update:tested the single gear setup yesterday. On the flat, it's function properly. On 10 degree slope, chain skips and I can't pedal off the saddle. This never happened to any cassette I own and operate at the cog with the same number of teeths or smaller. I don't recommend this product.

Very nice SS cog setup especially with the carrier to spread the load prevent damage to alu freehub bodies. It looks good too in red and black. On a converted mtb, I use this cog with a 10spd kmc chain w/o issues.

Changing multi -speed to single speed and this works better to than using one of the cogs that came on the bike

Excellent to convert to single speed

Works great on my mountain bike I just converted to single speed. No slippage on tough hills. I'm using a chain tensioner

Best product!

I like this cog because the contact area is so much larger than other cogs. So it will not leave grooves as easily, especially when you have an aluminum freehub.

This unique cog is the perfect weapon for any single speed mountain bike. Not only will it fit perfectly on a Shimano-style freehub, going "fixed" is as simple as it gets! The inlcuded spacer body and six allen head bolts screws onto the disc brake side of the hub, making your bike an instant and dependable fixed gear.I've gone trail riding with this cog bolted on fixed twice and absolutely love it. Prepare for something new and fun!
