## Questions & Answers

**Q: What’s the diameter of the innermost circle? The distance between the inner mounting tabs. 88mm or 90mm?**
A: Not sure I understand the question. The BCD is 104 but if you're asking about the distance from mounting tab edge to mounting tab edge (across) I came up with 88mm. Bear in mind that I measured this on the bike and it was a little akward so I could have been off a bit but probably not 2mm. If the latter best describes your question then I'll assume you're concerned about the chainring fitting on to your spider. I did have to remove a very little bit of material ( maybe .008") from the tabs to get the chainring to drop neatly but securely onto the spider. All ended well and I have several thousand miles on the new drive without issue.

**Q: Is this compatible with a 1/2”x3/32” size chain?**
A: yes

**Q: What's the difference between the 50t and 50t round options?**
A: They are all round, "50T Round" is a new packaging.

**Q: What does narrow wide mean? Is it narrow or wide? Make up your mind!**
A: The teeth alternate between narrow and wide. You can find videos about why  they do this. I like them because they don't wear as fast as "normal" chainrings.

    Nice product
  

*by M***C on Reviewed in the United States on January 28, 2024*

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

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It fit perfectly on Shimano crank.
  

*by G***S on Reviewed in the United States on October 17, 2021*

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.

    Works with Microshift Advent-X Groupset - You will need a longer chain
  

*by S***. on Reviewed in the United States on August 13, 2022*

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.
