Upgrading Custom Paramount OS....

I have a Paramount OS that was made for me in 1991. The frame is in great
shape. I am trying to understand if it is possible to upgrade to integrated
brake levers/shifters from shifters on the tube. I don't necessarily want
to buy all new Dura stuff, too $$$. My bike has a mixture of Dura-Ace and
Ult.600 with a seven speed cassette. I have been told Shimano makes the
equipment to accommodate the 7 speed cassette, but it is not of the highest
quality components. I think it is called Sora.

I have also been told that it is possible to spread the stays (not
permanently) in the back to accommodate a wheelset that would normally fit a
bike with a 130mm spread and therefore a 10 speed cassette. Mine is spaced
at 125mm. Getting a new wheelset seems the best stratedgy, but does it
really work?

Any thoughts or questions would be great!

If the rear derailleur is pre 7700 series, then you need to get Dura-Ace
shifters from the era. If you have index compatible Ult. 600, you can use
Sora, or any current shifter that matches the number of cogs on your rear
wheel.
