Alex had a nasty chain jam at walla walla with an old school unramped 45 she is using to get the junior gears with a 12 cassette. It's the conventional road bolt circle ( not compact) so likely very rare. But trying anyway.

Blackspire has 42, 44 and 46 tooth with ramps and pins online...

They are in Delta so it might be worth giving them a call.

Thanks Hugh. Good source to know about.
But I'm pretty sure she needs the 45t to make the roll-out rule.

Called blackspire, and though very nice there, they don't make a ramped 45 and don't plan to. Didn't bite when i suggested custom ones. No ideas where else to get. Back to the drawing board.

Giving up on a 45, how about a 52 with ramps and pins?
Hers is a 53 which puts her over the limit, or well under it on a 15 t cog. Maybe a trade if 1 tooth doens't matter to you?
