I can’t find a replacement 15 t sprocket for my Trek! Mine is having an offset of 3mm.
Where can I find it. I’m attaching a picture. Based in the US.

Sram do this one above that comes in 14T , 16T and 18T that is made for 12spd sram drivetrain, it has the small step you need on the Trek,I have one on my LT9.

This is a aftermarket brand below, this one is a 15T which is my spare.
This also has the step.

Impossible to find it in the US, nor Trek is having it right now. I decided to design and 3D print one and use a regular Bosch Sprocket. I mounted it

yesterday and it works. Now I’m not sure for how long but it may work long term.

I can provide the file is you want it

Oui c'est gros ... Mais j'ai 50 dents derrière (et région assez plate)

16 est plus que suffisant (et il ne déraille pas)

Hi - can you please let me know how you are getting on with the 18t sprocket ? - I am looking to do the same with mine. Does it really affect the cadence and presumably ability to climb effectively ?
Excusez-moi, mais mon francais, c'est tres mal .

For any future thread chasers - I took the 'chain protector' off completely, secured the cable to the engine casing with clips using the protector screw holes in the casing and swapped the 15t sprocket for an 18t Miranda sprocket w/3mm offset.
Also added a mudstop and bearing seal from performance linebearings. .
Runs like a dream and plenty of room to get crud out.
