This chainring is accurate to the BCD they advertise and it fits great for converting my 2 speed front derailleur to a single speed on my GT Zaskar with Shimano deore cranksetYou do have to account for some extra play with the chain because it will not be centered perfect unless you buy a specific crankset for a single speed, I've had no issues with mine so far however just anticipate the chain will wear quickerIt is a good quality sprocket and the coating on the paint seems to at least be somewhat durable, for the low price they ask it's a no brainer upgrade

This is good quality and great price. Chainring didn't look like the picture but it's ok as long as it works

I'm happy with sprocket,gonna order couple mo re

This is all you need to convert a 3X or 2x drive train to a 1x as long as your chainrings are not riveted in. Just unbolt, all three and bolt this one where the center one was with the included shorter nuts.Note - you can also cut down the bolts that hold the first chain ring on so the chain does not get smashed into your BB tube in the unlikely event you do drop a chain. I used a mill but I don't see why you can't do it with an angle grinder. See picture 1 and 2.love rant bellow:I can't believe how awesome the narrow-wide chaining is compared to a regular traditional one. No more dropped chains, even without a derailleur guide!!! For only $12 each we have converted 3 bikes over to 1X drive trains. You get no dropped chains and the ability to focus on riding and not shifting. Long live the narrow wide!!!

Has improved narrow/wide teeth over Shimano OE ring gear. Seems to wear ok after 500 miles on an E-MTB.

Deep red and looks great

Inexpensive, but the inner diameter was 89.5mm, ~.5mm less than the SRAM cranks' dimension (and my previous Absolute Black 32T) so I had to grind .5mm off of each of the 4 inner spots.

Used this on a budget 1x8 conversion and can't complain at all. I tried both oval and round cant really tell much difference but seems oval doesn't wear me out as much.
