I'm on the hunt for the above. 94bcd narrow wide 5 hole chain ring. To fit a pair of middleburns.

Thanks!

I bought a job lot from this guy a couple of years back,he's still got some listed;
https://www.ebay.co.uk/itm/123136671575?hash=item1cab847f57:g:RgwAAOSw4D5ajjzR 36t
https://www.ebay.co.uk/itm/123847585192?hash=item1cd5e42da8:g:~S4AAOSwcgxajjYB 38t
https://www.ebay.co.uk/itm/123868245448?hash=item1cd71f6dc8:g:bAEAAOSwJRVajjcA 40t

The 36t Pro series is slightly greyer,with shifting ramps.The other two Epic series,lighter silver,no shifting ramps.Needless to say,won't be looking for anything like the listing price.Anything suitable?I'm pretty sure they're classed as narrow wide but you may want to check.Happy to take any measurements.

I think those all have shifting ramps to my eye.

I think narrow wides have square tapered little flat teeth.

Those look a little post 98 to me.Apologies for my ignorance,is narrow wide a 10/11 speed thing?
The shifting ramps are the machined cut-outs on the back of the 36t ring (2nd pic),some Shimano rings also have the shorter teeth in certain positions to coincide with the ramps to aid shifting.These teeth are all the same profile.

The 36t has 5 shift ramps (different style to those pictured) the others have none.Not sure if you're looking for something a little more modern than I have?

Haha! Deffo post 98. I am learning today ! Is narrow wide, or 1x10/11 a more recent trend? How did they guarantee chain retention in the 90s?

 

[captaincowelly]

No wonder I'm confused!Witchcraft!!Get him out of here!! I'm assuming those chainrings are designed for the chain not to move off them,older ones are the opposite (triple front).I'm sure you'll find someone more educated in the post 98 section.Surprised they haven't tried to lynch you yet for that kind of talk round these parts!Good luck anyway.
