Hi everyone, I think this is my first post here in this forum ever!
I've been a crazy mad biker for over 43 years, (10 years old to 53), touring, commuter, racer want to be, worked with a bike (literally pedaling donuts). In other words I have used bikes in most of their capacities.
Presently I want to convert my 27 year old touring Cannondale 27" into a 700c tourer/commuter. Why 700c? Well, all my other bikes, from my backup commuter to my tandem they are all 700c, and I'm getting a 700c dynamo front hub wheel to fit both commuters and the tandem. I was going to wait a little to change the rear wheel but the gears are starting to slip, tooth on the rear cogs are worn ( to cause concern). This is the fourth time I have changed the rears cogs on this bike.
Being stuck in 80's and early 90's technology, I'm here for some education and advice.
The rear spacing on the frame is 125mm. I know I can fit a new hub with an 8 speed HD cassette to run an 8 speed Shimano's Deore XT integrated 8 SIS rear derailur (127mm maybe?), which I have on hand. I would like to run it with a Shimano's Dura Ace 2x9 brake shifters, also on hand, with an Shimano's STI HG new narrow chain/9-speed HG compatible, also on hand. My question is, besides loosing my grany gear in the front and having one phantom gear on the shifter lever, would the setup work?

My concern is that the movement (spacing) for the 9 speed is different than for an 8 speed and they would not work together, or the chain would not be compatible with the 8 speed deore XT derailure and cassette hub gearing. Thanks in advanced Double O
