Road Bars to Flat Bars ... Will this Work?

I'm thinking of "bastardising" my 2011 Specialized Secteur Sport as I find drop bars uncomfortable at times. I just want to double-check that the following components will be suitable for my proposed conversion:
Shimano R550 Brake Levers: http://www.chainreactioncycles.com/Models.aspx?ModelID=34695
Shimano Deore M590 9-speed Trigger Shifter: http://www.chainreactioncycles.com/Models.aspx?ModelID=40547
FSA V-Drive Handelbar: http://www.chainreactioncycles.com/Models.aspx?ModelID=77560
Getting the correct size handelbar is what I'm most unsure of. Bike specs are here: http://www.evanscycles.com/products/specialized/secteur-sport-2011-road-bike-ec025005#features
Please advise.

bars will be fine. 31.8mm
not sure how the brake levers will feel or work.

I used a FSA XC-190 stem 25.4mm £5.00 from CRC
FSA XC-270 Semi riser bar 600mm £5.00 from CRC
EV173755-NA-SVR shimano R550 brake levers for flat bars £15.00 from CRC
and a used Sram 9 spd twist grip gear shifts from our very own Dicey007
I'm using the existing road bike Shimano 105 cantilever brake calipers and 105 rear mech (short cage) with existing Shimano 105 front mech and 105 chainset 130 BCD with new 48t and 38t chainrings. ( the smallest possible)
Using the existing 9 speed 12-27 Shimano 105 cassette which will give approx 36" at the low end and 105" high which is ample for predominantly road and cycle track use.
I had considered fitting a 11-32t cassette but that would only have given a further 3-5" or so at the bottom end and It also would have required a new rear mech and chain and I wanted to reuse existing components where possible.
Biggest problem was ensuring the stem had the right reach and angle and had the correct dia for the bars I was using.
here is a pic of mine.
Ahh the 64 million dollar question to which I haven't an answer yet.
I cannot see why they should not but if they have a different pull per click then I'll have to use a cheapo Sram MTB rear mech which I got used from dicey007 last week.
Very nice looking bike by the way ,
I'm kinda thinking about building a flatbar bike for myself if this one feels comfortable.
I like the idea of bull horns myself so when I build myself a flatbar bike I might try your suggestion.

that makes perfect sense Nick !
i had to read that 3x times to see the difference lol. Could you please explain the difference between 'numbered' and 'named' for me. :roll:
The twistgrip shifters i am using just have Sram 9 written on them, they have a visual gear selected display . Fortunatel I purchased the matching rear mech with them so I can use that.
The biggest problem I face at the moment is sourcing a suitable front mech to use on a road frame with a Shimano 105 db chainset (130 bcd) . The MTB f mech I ordered won't fit between the seat post and tyre. :shock:
Does the twistgrip pull the same amount of cable as a road STI ? can I use a road front mech ? if not what type of mech will fit a road frame?
thanks for you input , much appreciated
I still have an old front mech (suntour i think) you can have for a fiver it came with my bike and X5 shifters. Worked well enough
X4 etc or older 9sl 7sl
named Attack,TRX,Centera,MRX,Rocket.......................
front mechs are generally cross compatible with varied success with road to MTB cross use

I'll order up a 31.4 band and try using one of my road fr mechs.cheers
