Thanks. Any idea what ST numbers I should be looking out for. Would it be 8-speed versions of 105 or Ultegra that were current pre-2008? Is there anything compatible that doesn't have the gear cable coming out of the side of the hood?

You say that your dissatisfaction with the Rapidfire shifters is the handlebar clutter, rather than the need to take your hands off the hoods to change gear. Given that, and given the likely relatively high cost (and possible difficulty) of getting suitable STI levers, what about downtube levers instead?

Not only are they less expensive than STIs, their simplicity and reliability would also admirably suit a bike fitted with drum brakes, and you could continue to use your current brake levers.

Nice idea but it's too late for that. My other main bikes have had STI or Ergo for many years and I have got used to them. I could never go back to reaching down to down tube levers.

On the latter point, yes, campag 10s ergos. Ought to be plug and play for shimano 8s mech

Shimano shifters that work include ST-

7400
6400
1055
2200
2300 (I think- do check this but I think this is the only model launched post 2008 that has the 'old' brake cable pull)
3300

as well RX100 double and a few others.

cheers

Many thanks for all the info. I'm guessing Campag ergo 10 will be the easiest to source. I'll probably start there.

easier to source? Hmm... There are some issues to contend with

1) not all 10s ergos are any good at all (recent ones are nowhere near good enough IMHO)
2) FD control is a bit hit and miss when you start mixing and matching. You will probably get away with using most versions on a double (even with an FD that isn't matched) provided you are not too fussy about trim positions
3) ergos have a different failure mode to STIs. Typically STIs fail by breaking (don't really work at all) or gumming up inside. Ergos can wear so that they appear to be working OK when you have them in your hand, but they either won't hold a gear or will do multiple shifts at once, and you only get to find that out when they are installed on the bike.

Most Ergos are rebuildable but for early 10s models some spare parts have gone NLA

With a shimano STI you will have to use a matched FD and RD obviously but there is a much wider choice.

cheers
