Trek 7.5FX Disc
I'm new here, and I have a question about Groupsets.
I have a fairly standard Trek 7.5FX Disc which I took down the Pacific Coast Highway this summer, from San Francisco to Los Angeles.
Having done that, I feel I need a greater spread of gears to what came as standard.
Deore Crank & Chainrings (48/36/26)
SRAM Cassette (11-26)
105 Bottom Bracket
105 Crank (175mm) with Shimano PD-M540 pedals.
105 Triple (52/42/30)
SRAM 9 Speed Cassette (11-34)
My question is whether the XTR shifters will work with the 105 Chainrings & Derailleurs. And whether the derailleurs will work with the SRAM Cassette.

I've been "revising" my Trek FX 7.5 - but not to extend the range of gears - stock is fine where I live/bike. But that is a nice bike and deserves better than what came with it - IMHO. So I...
Shimano Ultegra GS RD
Shimano XTR FD
SRAM Attack shifters - 9 Spd.
SRAM PG-970 "PowerGlide II" 12 - 26 9Spd. cassette
SRAM PC951 chain
MKS Campy-clone pedals, MKS toe-clips etc.
Panaracer Pasela TourGuard 700 x 28C tires
Avid SD-7 brakes (throw out those Avid SD-3's - weak and impossible to keep adjusted)
Kool Stop Thinline pads
Terry Fly saddle
Next: Building wheels (Bontrager wheels makes me want to hurl) - Mavic A719 32h rims, Ultegra hubs, 14/15 DB spokes.
Then, I believe, this bike will be at it's fullest potential for what it could be.
I've decided to go with
Shimano 105 Chainset 52/42/ and keep the 26 granny
I have the stock Avid BB-5 disc brakes, I may change them to V brakes on a carbon fork next summer
that will be an awesome bike with the 105/xtr matchup, a really nice light set of wheels with the carbon fork will make it super light too
