Alloy Chain Ring for SR chainset.

[Landsurfer]

Has anyone got a good usable chainring for this chainset. I've got a 52 tooth but want a smaller one, preferably 42 or smaller if they exist.
87mm BCD

144 BCD? Campag nuovo record clone.

Are you sure it's 87? Not listed in the Sheldon Brown table

BCD not PCD mmmm 84mm BCD .... I'll sort out the PCD .... Probably easier all round ..

Typical smallest chainring for 144 BCD is 42 (part of the 52/42 double combo), there is a 41 but quite rare!

Might be something on Hilary Stone Website, checked bankruptbikeparts and they have none apart from a 1/8"

Low budget bike build i'm afraid ..... thats why i'm after a usable 2nd hand one ..

There's a 42t on Hilary Stone site for £30.
Low budget? Use a crankset that you can get sensibly priced rings for, then.
I have looked at my stash and have some 118mm BCD but no 144s, sorry.

 

[Landsurfer]

The crankset was free along with the 52 tooth ring ....
"Use a crankset that you can get sensibly priced rings for, then."
I assume that you often mix up helpful with rude.

This is the bike ....... It has an FSA chainset fitted .....
It would be more appropriate to fit the SR chainset.

Is it for a single speed / fixed?

No it's a 9 speed ....
The icon to add pictures seems to have disappeared .... any thoughts chaps ?

Press the cog wheel on the top right of the menu bar and it should appear

It will cheaper to buy a complete used crankset
