Hybrid Bicycles - frame for hybrid?

Does it take a road, touring or cyclocross frameset?

I'm looking for the IMPOSSIBLE! What do I mean? I mean I want a bicycle with a comfortable upright position, thumb shifters, adjustable stem, chainguard, mudguards, backrack, 52T to 11T gearing (yes, lots of long stretches of downhills here), no suspension, plastic pedals and 700x47mm tires (with rims with 21mm inner width and schrader vavle).

I've looked at all kinds of sites. The Kona Smoke is kind of close, but I need to modify it to get what I want.

build yourself up a Surly Crosscheck with a flat bar. or a Bianchi Axis, or most cyclocross bikes.

I'm not sure what the maximum tire size is, or if you're willing to go with an IGH, but the Jamis Commuter 4 with its 18t sprocket gives the effective range of an 11-34t 8speed cassette, you'd need to change up the chainring to a 52T to match your requirements...

Not sure about the stem type on the tubes, but adjustable stem is there, flat pedals (I'm not a fan of plastic, but I get why you'd want them, as they are less likely to cut you if your feet slip off, but there are alloy pedals that work well in their place and have a much longer lifespan and better bearings)

I have a Niner Sir 9 set up as a hybrid with Big Apple tires. A 29er and no need for suspension since the tires provide them. Its a good all around ride.

The 47mm tyre requirement might be a bit of a stretch for most cyclocross bikes - the UCI maximum is 35mm. Most bikes go somewhat beyond this, but you'd have to check carefully.

Anyway, I'd agree with NormanF that a 29er MTB would be the best match - they have more clearance usually than crossers. Or indeed a 26" wheel hardtail MTB. You should never be put off by the gearing a bike comes with as stock - changing a cassette or chain rings is easy, and you should be able to get the bike store to refund the cost of the hardware the bike came with. An even better option might be to order something like a Karate Monkey and have it built up with a Nexus internal gear hub instead of derailers, choosing a suitable single front ring to get the gearing you want. Much less maintenance that way. This shop is legendary - they'd do a great job of advising you and building the bike:

As for "must have plastic pedals" - for goodness sake, don't you know how to use a spanner? Pedals aren't welded on! And a bike shop will fit any bike with schrader or presta tubes as you wish, if you're incapable of changing a tube yourself. Really: relax. Bikes are just collections of parts attached to a frame - you or your shop can do almost anything you want.

I built up a flat-bar Fargo. It'll handle any width of 29er tire on the market -- 47mm will be no problem. It's also got all the mounting options you'll need for fenders and racks. I don't run plastic pedals per se, but I do run "flats".

Do you mean the Salsa Fargo? Has anyone tried the Soma Saga Touring frameset?

Do you mean the Salsa Fargo?

Yes. Right now I've got it built up w/flat bars.

The Schwinn Super Sport DBX. Comes with drop bars but you can swap them out to make a comfortable hybrid commuter. Fenders are optional and it will accept up to 700X35 tires. You'd have to modify it to get triple gearing and wider tires but no biggie.
