I have a late 80's (1987?) Cilo road bike. It has a shimano biopace dual crank and 6spd cassette. I like the bike and would like to upgrade it to be a triple crank (for hills) and 9 spd cassette. I was thinking of Shimano 105 components. Is this practical / doable?
Any comments / suggestions would be greatly appreciated.

This bike is most likely spaced for a 126 mm rear hub. If it's one of the steel Cilos, re-spacing it is a trivial matter, and it's well worth the upgrade.
If it's one of the glued aluminum (Vitus) ones I'd be nervous about spreading the frame.

You might want to read a recent thread here on compact cranks (ie cranks using smaller chain rings). These permit one to easily achieve the lower gear ratios found on most triple cranks without all the fuss and expense. Useful with any number of cogs in the back.

Yes it is doable. It will take some work. You will need to have the spacing on your rear triangle re-set to 130 to accept a 9spd wheel. You will need to buy:
rear wheel 9spd cassette 9spd chain 9spd cranks matching BB That is a minimum. If you want to go to STI, then you will also need the STI levers and an index compatible derailleur. Check the prices on these parts and then you can decide if it is worth it to you. --------------- Alex

Maybe new cranks, BB and front der are not needed?

For conversion to 9-speed, they're not needed, but the original poster also mentioned that he wanted to upgrade to a triple in front.
The O.P. could save a lot of money by going to a wide range cassette and leaving the cranks alone. This would require a new rear derailer, but derailers are cheap. He could get much lower gearing than he or she has now without changing the cranks. Going from a 42 to a 38 tooth small chainring would also help, again at a much lower cost than going for a triple.

My thanks to all of you. I had said that I was looking to go to a triple crank, but the responses I've received will make me think about that. Options have been brought up that have me thinking that for a start, I may just go to the 9spd and perhaps a triple crank later.
Thanks again to all.

That would be true, except the OP said he wants to switch from a double to triple crankset.

Sorry, you (and Sheldon) are right... I should read more carefully!

Have a good bike shop cold set the rear triangle to 130mm. Shift levers, crank, BB, front and rear ders, cogset and chain. Easy and doeable. Also look at Campagnolo Veloce, probably cheaper and more durable.
