[Closed] 20 tooth 4 bolt chainring......where from?

I thunked 22 was the smallest before the bolts get in the way?

When I worked for Edinburgh Bikes Wwe got a Triple chainset from TA with a 20tooth 4 bolt smallest ring for a customer doing a custom Van Nicholas build.

If you were really lucky (this was about 7 years ago) they might still have one because we ended up with a spare.

Either way, TA could be your best bet for 20 tooth chainrings.

middleburn do a 5 hole one. bit dear to swap cranks too.

You might be able to squeak it, these bolt holes are 10.05mm on a 64mm BCD-

Sanny uses 20T to winch himself up proper mountains, dunno where he gets them from I'm afraid.
