converting stem shifters to brifters I'm new. I'm 26, from the UK and until last year I'd never cycled more than 10 miles before. Then in September I cycled 2700 miles from Maine to Florida. It was great.

I've just bought a Dawes Galaxy, I believe made in about 1997. It's got a Shimano RSX rear derailleur, 7 speed, indexed shifters. Three cogs on the front with friction shifting. Shifters are on the down tube.

My plan is to buy some Shimano brifters. I was hoping to upgrade the down tube shifter into the integrated brake shifter. Could anyone give me advice on which Shimano sets would be compatible? I imagine any Shimano 3x7 would work. Is that correct?

Would these work?

Other equipment I believe I'll need is: cable housing, wire, crimp tool, end caps, bar tape, cable tensioners ... What do I put in place of the current shifters, some sort of cable stop?

Anything else I would need? Anything else I need to consider?
You can buy any 7 speed Shimano brifter (or compatible ones made by Microshift). The ones you link to are fine. The front derailleur needs to be Shimano road.

You'll need:
- Cable stops on the downtube
- New cables and cable housing (brake and shift)
- Probably new bar tape

The tools will be cable and housing cutters, an awl, a file and some screwdrivers/hex keys. 

Not sure what you mean by cable tensioners.
