	Anybody have a shim? Or I can trade a xt front dérailleur ( top pull, bottom swing 34.9) for a similar 31.8 clamp dérailleur

	Don't think you can shim from large to smaller diameter but I have a 31.8. Will have to check swing and pull. What model is the XT?

	Have FD-M737 XT in 31.8 and a new Deore that is 31.8 or 34.9 with integrated shim.
