Source For Sprockets
 

I am looking to change the gearing on my following bikes:
ADR125-2 / 154FMI
AGB-36C / 166FMM

I am trying to find the sprockets locally, or worst case North America. I would prefer to not wait 30-90 days for them to arrive.

Any tips where I can find sprockets to fit these bikes?

JT Sprockets seems to be the oddball and post the dimensions of their sprockets... sadly none of the ones I checked fit.

Thanks,
Ross

Any pic???
Find out the type 420/428...1st
Measures & compares those pic in JT catalog. If still can't find it, ask http://www.jtsprockets.com/contact w/ EXACT measurement...

The ADR125-2 / 154FMI is:
428, I am looking for 12 or 13 tooth

The diameters are 14mm, 17mm with a 4mm flat or whatever it is called. The bolts are 5mm and 30 mm apart.

The AGB-36C / 166FMM is:
530, I am looking for a 12 tooth

The diameters are 18mm, 20 mm with a 4mm flat. The bolts are 5mm and 34 mm apart.

I scoured the JT catalogue as best I could last night. I was not able to find a list, I had to go sprocket by sprocket... fun times ;-)

I will contact JT, thanks for the help.

[ADR125-2] 428: JTF273 420: JTF249
[AGB-36c] No idea yet

Thanks, You did what I could not last evening!

36c: https://translate.google.com/transla...496&edit-text= said that's a Loncin :hmm:

The dimensions seems to indicate it will fit.

They also have a 428-13...

Any experience with delivery times from them?

No idea since i can't read Dutch...

You are awesome, thank you very much for all of your help.

I did learn something. Searching for 530 12 is not the same as searching for 530 12T... I guess I should have known. Lesson learned/relearned.

Just found this sprocket, looks like the listed dimensions match what you're looking for.
Hope i got the link right.

Nice and thanks!

I ended up going with buying blanks for my rear and machining them. Or at least, I have bought the blanks but have not got around to machining them yet ;-)

I went ahead and placed an order for one of the Amazon sprockets i linked for my AGB-36, I'll let you know if it works out.
Update.
The Amazon sprocket bolted right on, and works great.
