I wouldn't. The SJ M2 is a race frame and Specialized did not intend riders
to use cargo racks on them. The drop-outs are a minimalist design and
drilling for a rack would seriously weaken them.

If they are the type with an opening, you might be able to find some
Blackburn Campy rack adapters. They fill the opening, creating a place to
bolt the rack.

Another thought is using the plastic coated metal bands around the seatstay
just above the dropouts. This worked on my 96 Ground Control.

If you bougtht the bike/frame new you'll be voiding the warranty.

Very much so.

If you don't have rack mounts, look for racks that attach solely to the
seat post, like the Blackburn SP2.

Whoa, cowboy! Put your drill away right now!!! You might weaken the
frame, and you will void the warranty.

Your options are
1. seatpost mounted rack;

2. the little plastic coated metal straps that come with most of the $20
racks (and are overflowing out of a drawer somewhere at every bike shop
in the Western world);

3. Beefier thick alloy clamps designed to attach a rack to an
eyelet-less frame - the alloy clamps will last longer then the tin
straps if you are carrying a load. The straps will break eventually they
are subject to much stress - they are designed to hold the front -
facing stays to the top of the seatstays, which is a very light load. If
you use the straps to hold the bottom of the rack then they are
responsible for carrying a large part of your load.

I don't know who makes those clamps, though, or where you can get them.

Thanks for the warnings. (I can almost visualize the look of panic in your
eyes as you wrote the replies). I will check into the seat mounted racks.
