I have a front derailleur you can make use of for spares.
Also got a complete black/silver groupset available but not keen on splitting- just thought I should put it buy you if you might be tempted/wanted one in this colour.
Righto, well I'll be making a trip to my storage lockup tomorrow so will pick up the derailleur then and be able to think of a price. BTW as you might need other bits from the same groupset, I know I also have a first gen large flange hub built into a Mavic rim in the lockup. Say the word and I'll retrieve this too.
