I recently got a full Centaur 10 spd triple groupset second hand, but since I'm in a flat part of the world I've decided to get a double chainset to save some weight. But I don't want to lose the advantages of the triple in case I want to go somewhere hilly, so I am wondering if I can set the bike up so that it's easy enough to swap chainsets?
I will probably need a 111mm bottom bracket, which works with the double and maybe also with the triple.
Can I use the triple front derailleur with both chainsets (53-39 and 50-40-30) or do I need a double as well?
I will get a medium cage rear derailleur which according to Campagnolo works with both triple and double chainsets (I have a 13-26 cassette).
I hope somebody can help me save some money! Advice appreciated...
