Surly cogs hold up wonderfully!

I am a big fan of these cogs. They are reasonably priced and last for a long time. These cogs will love you long time! I have used the Niner Cogs for my One Nine and could not get them to last long at all. Surly cogs hold up wonderfully! Thanks for reading

I'm not the strongest biker in the world, but after several hundred miles of riding on this (until I was ready to move up to a 20-tooth cog), I compared the tooth wear to the measurements I took of the original (I'm an engineer, so I do this kind of nerdy crap). Even with my best Mitsutoyo I detected no noticeable wear (ie the wear was within the error range of the instrument). My next cogs will be Surly, for certain.

These are quality cogs. They're not super light, but they wear incredibly well. I just purchased another after running my previous one for around two years of fairly aggressive singlespeeding.

I received it so fast buy the time I wrote the feedback I got it confused with another order. I'm using the gear on a 52t fixed gear where it worked perfectly with zero chain noise. Good price, high quality product, keep the vender's name for future orders.

Getting into the larger cog sizes, I opted to go for a better-built product than the cheap chinese stamped stuff. These cogs are tanks. They are heavy, but a full summer of use on my ss29er shows zero wear. Well worth not worrying about, in my opinion.

I had purchased a 22 tooth version but decided that it made my gearing a little too low so I purchased this 20 tooth version. These appear to be quality cogs and should last.
