Thanks for the replies chaps :)
Just to clarify – I actually do have a triple. I built up a Kaffenback 2 over the summer with mainly 9spd sora (STIs, front and rear mechs and 11-32 cassette ) coupled to a stronglight 28/38/48 crankset which I will probably use for light touring. At the moment it’s not quite set up right as I’ve got some chain rub in the middle ring which I’m hoping to fettle out. It disappears when I put a bit of sideways pressure on the big lever, which I think means I need a bit more cable tension (i.e. moving the lever moves the mech outboard a tadge and the noise disappears). Maybe I should give up on STIs and use bar end friction levers :)
Stronglight also do the crankset in 46/34/24 so I could lower the gearing more if I felt the need (hopefully the front mech would work with the low tooth count of the smaller ring).
The original post was whether I could make a lower geared pootletouring CdF with a double (more out of curiosity unless it was really simple and cheap).
CFH – I might possibly be more svelte than you but I bet I’m older with worse posture both on and off a bike :) Someone once described their posture as that of a wok smuggler and I expect my back looks a lot like that :)
Mr Poddy – I’m suprised you didn’t suggest that I buy a Tour de Fer. :) I’d quite like to see one of those in the flesh.
