ProsThick, round, reasonable price, reversible
All these good reviews are right. This is a great chainring for fixed/singlespeed bikes.

It is nice and thick, making for a really feel. I was able to use double-chainring bolts on a road crankset and this chainring, which was convenient.

It seems to be well made and nicely round (!) - no tight spots (though I paired it with a high quality chainset which helps).

Great quality, lots of choice and good value.

ProsFinish
What looks wierd is the thickness of the chainring body against the thin 3/32 teeth. Because it is reversible, it has chamfers on both sides of the chainring bolt holes which results in a thick thing. If you can live with that, it is a nicely made chainring.

Have bought 4 3/32 rings and all have worn well with the bonus of reversibility. Good quality kit. How about a quantity discount?

Have bought 4 of these c/rings for 4 Fixies including a turbo training bike. Proven to be reliable and smooth. Price could be a little more competitve if buying more than one. Buy the thorn c/r bolts as standard alloy bolts tend to split with higher gearing.

I bought this as part of replacing my current cranks and is fantastic. It looks good and most importantly is quite than what it replaced.

As always had wonder service from SJS.

Reviewed this when I bought one last year. It has been on the fixed road bike all year and I have now decided to get a different size for more gear options. First one hardly looks used, no question in buying the same item again.

ProsSolid, Well made
Fitted this but not ridden it yet. Fitted on fine but is thicker than normal double chainring. Looks great and feels very solid. Good service from SJS when I had a subsequent question about the diameter of other sizes.

I'm turning my old fixed into a SS cross bike. For a laugh. Previous chainset was a fixed tooth Stronglight with 44 teeth. I had a spare triple chainset that looked like it would do the job, and allow me to change ratios. This ring, though unridden, fitted fine - build quality is great. It's sturdy and tough, and ought to last well, especially though the double sided nature.
Excellent Singlespeed / Fixie Chainring

Consnot supplied with chainring bolts
ProsGood Price, Hardwearing
This is a very well-made chainring, suitable for any fixie / singlespeed rider looking to replace or upgrade their exisiting set up. fixing it to the bike is a piece of cake (remember to retain the chainring bolts from your current set-up), and the build quality is excellent. Being two-sided it is very sturdy and perhaps a shade wider / heavier than other single chainrings on the market. The ability to reverse the face should give the ring twice the life of other 'rings.

You can stop using rings designed for shifting on your singlespeed or fixed bike; these are stiff, round, reasonably priced, available in all the right sizes and they have proper teeth which won't let go of your chain the first time you hit some rough stuff. If I ever wear it out, I'll tell you about the cool double sided feature, which lets you use them for twice as long by wearing out the other face of the tooth by turning the ring over

Mounting Hole Thickness?
By
24 Apr 2015
Can you tell me how thick the ring is at the mounting holes please? I'm wondering if it will stand proud against my cranks spider.
SJS Customer Service:
Hi,

The ring thickness at the mounting holes is 5mm for these chainrings.

Thanks.
