Title: Looking for 42T 3mm offset 3bolt chainring
Post by: kenmc on September 22, 2025, 02:56:50 AM
Does anyone have a link for alixpress for a 42T 3mm offset chainring with 3 bolt mounting pattern?
I can only find sub 40T 3mm offsets - anything in 42T seems to be 0mm offset.
thanks


Think i found the last one on ali! https://www.aliexpress.com/item/1005009384051095.html
Just after posting the initial question. typical.

You may also take a look at these

Bit pricey, unfortunately, but aero gains are worth it  ;D

I've had a bad experience with the Wuzei chainrings. I got a narrow-wide 44T (104 BCD, not 3-bolt Sram mount) ring to use with a GRX 12-speed chain. But the wide tooth of the Wuzei chainring were too wide for the chain. This caused some chainsuck, but mainly a lot of noise from the chain "popping" of the tooth at the bottom of the rotation. I could even feel this vibration through the pedals.

I've since replaced this ring with a Deckas chainring, this one is great. But as you found out, these are only available in 3mm offset with the 3-bolt system upto 38T (mine is 104 BCD with a offset spider).  I've also used the Pass quest rings that bichler.bua linked. Those are great too, but a bit pricier.

You could also just get a 0mm offset chainring in the size you want. And use a washer like this to get some offset:

But make sure you get some longer bolts for the 3-bolt connection aswell (like in this set).

I run this Wuzei
https://aliexpress.com/item/1005008653144864.html (https://aliexpress.com/item/1005008653144864.html)
with a KMC 12-speed chain and Rotor cassette.
It is a 4.2mm offset, works fine for me.
