Surly Stainless Steel Chainring

Surly Stainless Steel Chainring

Surly's Stainless Steel Chainrings are perfect for singlespeeds, fixed gears or riders simply wanting a stronger, stiffer, prettier chainring. Although they are slightly heavier than alloy chainrings, they are considerably more resilient to impact and will last over twice as long as alloy chainrings. Also, once worn in one direction, their symmetrical design allows them to be flipped for double the lifespan, making them more economical than alloy rings! These non-ramped, non-pinned chainrings have a beautiful stainless finish that will upgrade the class of any bike. These are compatible with most standard bolt circle diameter cranksets, and can be used just fine with multiple front ring setups, although shifting will be slightly slower than with a ramped chainring. These fantastic rings come in a variety of bolt patterns, teeth options, and BCD. Check the options menu for the chainring that will fit your application.

I have no idea where...
I have no idea where the previous reviewer thought that they don't work with.. well any chain, apparently. Maybe they had a bad chain line or rusty chain? I first used this ring with a mediocre 9 sp chain, and now I'm using an 8 sp. Both worked- great. There are no instructions that should be necessary as long as you know how to tighten four bolts.Best chainring I've ever used.

The chain ring folded under pedal power. Very surprising.

When all else fails...
Read the instructions, or rather the recommendations when it comes to chain compatability. Surly says:

Our 94bcd,104bcd and 110bcd x 34/35/36t chainrings are made with a 2.2-2.3mm thick stock plate and work best with 5-8 speed chains. Many folks are using these on 9 speed drivetrains but this can often results in a "tight fit" right out of the box (This will loosen up and shifting should improve after the chain breaks in). The 110bcd 38-50t and all 130bcd chainrings are machine finished to have a 2.1mm tooth thickness and thus work fine with 9spd chains.

I've never had any problems using these rings when used per Surly's recommendations. Very durable and oh so shiney... mmmmm.

PROS: Durable, Easy To Install

CONS: Limited Compatibility

BEST USES: Casual Riding, Mountain Biking, Road Biking

Used this on 1x9 drivetrain, dropping down 7 teeth on front, 40t to 33t. The change is not as radical as expected, but seems to be perfect for hilly seattle. Now I get rest time after finishing a steep hill using the easy gear.

Bit heavy, but shifts like a champ
Bought this to replace an old bio-pace on a bike with no SIS. Easy install and perfect shifts so far in over 100 miles of usage. This should last me forever.

PROS: Strong, Excellent Shifting

CONS: Heavy

This chain ring has been on my single speed for a year of serious Western Washington abuse and shows no signs of wear. I use a SRAM 8 speed chain - fit has been no problem. This thing looks awesome too (when I wipe the grime off it).

Surly Stainless Steel Chainring
I have used Surly chainrings on my single speeds for a long time. I got this one for my 1x9 and I like it. I think these chainrings are very durable. I know I could get a lighter chainring but I am not a weight weenie. :)

love this chainring...
love this chainring for all single chainring applications. beats aluminum any day for actual all-conditions riding reliability. not light and nimble, but will never fail you, and will never cause chainsuck (just keep your chain in good condition).

Great product
I bought this chainring to put on my singlespeed. It was very easy to install and works great (as intended). It's made of stainless steel and therefore should be durable during my winter rides. My only wish was that it came in black. Another great Surly product!

What chain size would you recommend using with a 32t 4 bolt chainring?
Dan on May 5, 2016
BEST ANSWER: This chainring should fit any multi-speed chain from 5 to 12 speed.
Will this chainring be suitable for use with an internal gear hub?
A shopper on Mar 7, 2017
BEST ANSWER: Yes! Surly designed their chainrings around 1 x and single speed applications. Internal hubs with their single cog mimic a single speed and the chainring cannot tell the difference.
This is to replace a middle chainring on an old Shimano RSX crankset.

What is the bolt circle diameter I should be looking for seeking a 36 tooth chainring?
Natalie on Jun 6, 2016
BEST ANSWER: The BCD may be engraved on your current chainring. If not, measuring the BCD of your crankset is the best method to ensure a proper fit. Wolf Tooth components has a nice "How-to" on their site here:
What is the outside tooth diameter of this 35 tooth sprocket?
