Description

The Splined Single Speed Cogs from Surly breathe new life into Shimano / SRAM freehub wheels. They're machined from CroMoly and then heat treated and chrome plated for a durable, smooth finish. Tall tooth profiles help chain retention, and the 4.35 mm spline width better spreads out the load on the freehub body to avoid gouging. The wide base of the cog also means several sizes can be mounted together and then shifted between using a 9-speed derailleur and shifter. Sizes 17T and larger are drilled out to save weight.

Compatible with 3 / 32" 6 - 9 speed chains, but Surly recommends the use of the narrower 8 or 9 speed chains.

SS cog to rule all other cogs

I built up a 20lb SS hardtail this summer and tried an 18 and a 20 tooth cog, b ut the 19 was other sweet spot. The Surly was best because not only did they make a 19, but it has a wider base so it cannot hurt the cassette carrier, as some of the other cogs were not so nice. Don't cheap out and ruin your free hub - and an aluminum cog wont; last long on a SS.

My Go-To Cog

I have used Surly cogs for 12+ years on my MTBs. Cogs between 16t - 22t have equipped my bikes without issue. There are lighter, flashier cogs on the market but Surly cogs are strong and reliable plus their price makes them a very good value, full stop.

If you can afford those expensive, unobtainium cogs, go for it but Surly cogs are tough to beat.

Great SS Cog

I have had great success with these Cogs for my SS bikes. I typically wear out most cogs quickly but these last me 1-2 years+ before they start showing wear.

Very Nice

One of the best options(for price) for single speed cogs, these cogs have a large enough surface area which helps avoid eating into freehub bodies.
