  • Oval 52 tooth
Color: Black Oval Size: 52T
First oval I've ever tried, I am liking it,

  • Excellent quality chainring
The Deckas chainring is a quality one. I put this 38T to convert from 3x to 1x on my XC bike, I don't go off road too much just gravel and around the neighborhood so this works out well for me. I have 9 speed shimano rear hub set up and it works flawlessly without chain noise going from largest cog 36T to smallest cog 11T. Longevity? Only time will tell. ... show more

  • Awesome looking!

  • Worth for the money..at least
Color: Black Oval Size: 40T
Appearance, dimensions fits exactly.. The only part I've seen needs improvement is on the mounting holes, it must have a countersink or counterbore for the mounting screw to sit in exactly. If the nuts are not tightened enough, the chain ring will move..

  • Ordered new, received used.
Color: Black Oval Size: 42T
I've used these on a couple bikes, with no complaints. Great for the price if you want to try an oval without committing too much. However the one I got today showed obvious signs of being mounted and ridden for a bit. I'm sure it has no effect on performance, but it's a bit of a disappointment to receive a used product when you paid the price for a new one. ... show more

  • Works on my Poseidon X
Color: Black Round Size: 44T
I live in a fairly flat place, and the stock 38 by 11 just felt really slow to me, so I replaced my 38t chain ring with one of these 44t rings. Seems to work just fine, hasn't dropped the chain or been mangled yet.

  • great chain ring for the money.
Color: Red Round Size: 38T
i bought this ROUND aluminum DECKAS 38T chainring to replace my stock STEEL shimano 36T chainring that came on my shimano steps e motor. great variaty of sizes and color of chainrings. for the Money you cant loose. the red chainring is trick looking against an all black bicycle.

  • Price is great ! Lose the printed branding and lower the price a little more!
Color: Black Oval Size: 38T
For the price, it is a great deal. I have absolute black, wolf tooth, raceface wide narrow rings. I dont see a difference in terms of initial quality. Alloy seems good enough to last for now, no drops yet in 50 miles or so.
