Front mech shims

Hi guys,
I'm waiting on my new frame to arrive and I reckon that my 34.9 front mech won't fit because of a smaller seat tube size.
I've found in the mech box two shims of different sizes. Do these both go in together or do you just put one in?
I haven't got the frame yet so I can't check but I just wondered if these clamps should have two parts each rather than just one. It's a Deore mech btw.
They look like these, one is thicker than the other
Thanks for any advice,
Dan

it depends on what you actually have.
Deore has had a few changes over the years.
you will just have to see if the fit in/around the mech band."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Thye will have the size marked on them they shim it down to, you need both marked to the same size as the frame, most LBS will have a few left over from fitting front mechs to 34.9's, mine did, got a pair for the daughter for free.

Thanks Nick, I'm sure they'll reduce it but the inside of the clamp will no longer be round if you see what I mean. I just wondered if they were normally installed as a pair or in singles.
edit: Thanks Simon, I'll ask in the LBS then0 -

a pair or 2 pairs depending on what you have."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."
