I have shimano 105's - double ten, less than 80miles on them - I'm looking to go to flatties as I really don't like the drops. They are double only not the double/triple combined unit.
I can sell them on their own for £120 posted (tracked) or £140 with Ritchey tape and Syntace 6061T6 bars and brake cables.
You can click the gazelle link in my signature to see them on the bike - other parts of the bike might be available if anything catches your eye - I'm looking for a triple chainset too.
