Bicycle Mechanics - Any hope of upgrading?
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
A friend of mine has an old (25 years?) Raleigh "10-speed racer" type of bike that he hasn't ridden for a long time and is thinking about getting out again. He mentioned to me that he'd like to replace the downtube shifters with bar-mounted shifters/brifters like he sees on newer bikes. I told him that it was not really feasible for a number of reasons since he'd probably have to change over his whole drivetrain, and his frame was built with narrower dropouts and a wheel size that's obsolete now.
Am I correct in my assumption? Frankly, I think he'll have enough trouble just getting replacement tires & tubes, let alone trying to find different shifters that would work.

Replacement tires and tubes aren't a problem... but it could cost as much to upgrade as it would to buy a new bike. Unless his objective is a unique bike, or he has a sentimental tie to the bike, then looking to buy a bike is probably the easier route.
I wanted unique, and I bought a 20 year old Schwinn Voyageur and had the LBS update it to modern 105 for me. Compact double 10 speed with custom built wheels, nothing too special, but wanted to stay with 27" with modern hubs due to the cantilever brakes. The build with wheels, BB, crank, derailleurs, brifter, chain, small parts and labor was $850. I used the existing brakes, headset, seat and post, a Nitto handlebar and tires I already had. I could have cut that by $200 or more by judicious buying and doing the work myself, but still not a cheap upgrade.

You can upgrade ANY bike if you are willing to throw enough time and money at it.
If his Raleigh it is really a true "10-speed", i.e. it has a 5-speed freewheel, it will, as you said, have narrower dropouts than currently standard (probably 120 mm instead of 130 mm), 27" wheels instead of 700c, uses a freewheel instead of a cassette and may even have Raleigh's proprietary bottom bracket threading.
If it is new enough to be a "12-speed", i.e. 126 mm dropouts and standard English bottom bracket threading the situation is better but still expensive.
Any of these things can be modernized but, by the time he changes what's needed and buys suitable newer components, he is likly to have more than the cost of a new bike in it. This is particualrly true if he has to pay a shop or mechanic to have the work done.

Upgrading is possible but not practical.
My advice to him would be to ride what he has for a while to see if he even likes riding a bike. If he likes it and wants a more modern bike, sell the old one and buy a new one.
