104BCD 40T 42T 44T 46T 48T 50T 52T Narrow Wide Chainring Single Chainring for 7/8/9/10/11/12-Speed (Round)

So far, this has been a durable chainring. Chain retention has been good, works well.

I like this a lot, it’s inexpensive, took only about five minutes to install and performs well. Going from a 44 tooth to a 50 tooth chainring not only gave the bike a much higher high gear, it also gives a much longer power stroke, that gave my body a much better workout too, it’s now like a mobile step machine.However a chainring that much bigger was too much for the front derailleur, so I removed it and now just use the rear derailleur, but that’s ok with me.

I have a 2021 Poseidon-X gravel bike with 1x10 Microshift Advent-X groupset. The cassette is 11-48 paired with a 38T chainring. The gearing ratio is excellent for climbing steep hills but not so great on flat road surface where I usually ride and quickly find myself spinning at 10th and out of gears. Going from 38T to a 46T chainring changed the gearing ratio where I can now cruise at 8th gear faster than 10th on a 38T ring. As for low gear, I really didn’t lose much on climbing considering the 48T pizza-sized 1st gear.One thing worth mentioning especially for people with similar 1x10 11-48 drivetrain I have; you will need a longer chain. The 116-link x10 KMC chain I bought was short by about three links and had to use two master links, plus a link from the stock chain – also an x10 KMC.Build quality of this 46T Deckas chainring is not bad and comparable to more expensive brands – SRAM, Shimano, Race Face, Etc. I will have no reservations on recommending this brand to anyone looking for 1x chainring upgrade.

Just what I was expecting. Delivery was prompt and installation was relatively quick and easy. This was for a conversion to 1X so I mounted to the back side of the spider. I had to remove the slighest bit of material from the mounting tabs to do so. They mated up perfectly with the front side but were slightly long for the back. No biggie. The narrow/wide profile is working perfectly. I am not using a chain keeper (guide) nor am I using a clutched derailleur and have not had a single chain drop in the 600 or so miles since installation. Many of those miles were on some pretty awful roads and or trails. Operation has been smooth and near silent. I am pleased with the product and would recommend. I'm not going with 5 stars simply because I haven't put enough miles on it to be able to gauge wear and long term performance. So far though, it's been great.

Changed out the oem 42 tooth for this 50 tooth, for better use of gears on my magicycle. To lessen the ghost peddling at higher speeds. My avg is 15-20 but this seems perfect for me, even lower speed its very good.

If you always need assist them don't get a lower tooth count chain ring. If you want to use the E bike without assist and save the battery the find your gear inch range and lower the range accordingly. Save your battery cycles and save $. If your "ghost peddling then you do not need assist! Shift gears like a regular bike and enjoy long battery life.

I have two of these on different bikes to replace the solid steel chainwheels for Bafang. I do wish they would make some offset chainwheels to perfect the chain lines. The current alternative (Lekke) is priced too high.

46 tooth cog works great on my cannondale topstone 4 with adventX. I added an extra link to the chain in order to not stress the derailleur too much.

It looks and fits great. Easy to install. Fast shipping.

So far so good, installed perfectly and working great.Note; I have the 50t and the appearance is slightly different than pictures (the lightening slots are much more prominent, which is to be expected.) They seem perfectly symmetrical so I installed mine backwards so the logo faces inward, I prefer the "clean" look this way.

Very happy with the service will order again

It works well, fit perfectly. I flipped it so all the branding is on the inside, it looks cleaner that way.

Muy buena calidad y muy ligero
