There is a thread on this forum where geo charts for 2004 HP c40, and earlier pre-HP c40s & modern c50 family are embedded in one page. I found it pretty easily using the search function for this forum only - that way all other extraneous info is weeded.

Thanks, I found something here on the geometry.

If you know the year I can check if I have that year's catalogue and geometry. There was a least one change in geometry in C40 over its years of production.

Thanks, I will see if I can find that out today. That was the subject of another thread that I started. I was on the net last night scouring it for information, and the closest I got was that there was a change from an aluminum BB to to a titanium BB, but I don't recall the year. Maybe 2002? I pretty sure the BB in the one I have found is aluminum. Do you know when they stopped probuction of the C40?

I thought I read in one of your other threads that the switch from Alum to Ti BB shell was tied to the B-stay introduction. I am very interested in this bit of information as it would definitely affect my buying decision. For longevity purposes, I definitely want a Ti BB shell. I am close to pulling the trigger on B-stay c40 that is probably a 2001 or 2002. If it has an Alum BB shell, I might have to get the other one I have in mind.

Hi, Unless it is an aberation, I would say that the BB in the C40 B-Stay (non HP) is aluminum. I called Colnago America, the Colnago owned, but based in Chicago American distributor. I spoke to the sales manager, and while he couldn't remember all of the details, he did say that the C40 B-Stay was in production until around 2002/03, at which point they introduced the HP version which had the weird chain stays, 1 1/8" stearing column and the ti BB shell. However, he also said that most of the reported problems with the aluminum shell was a result of the bikes being ridden in the rain frequently, and then not being properly cleaned and dried afterwords, so corrosion set in. This was made worse where the bikes were ridden where salt is used in the winter, which would make sence. He said common sense with any of these bikes dictates cleaning them properly after a ride in the wet weather and making sure things are properly lubed.

I have a 2004/5 Master and unless I get caught in the rain, it does not get wet, and when it does, I clean it, starting with a full drive train clean and lube. The seat post comes off and the cranks come off to make sure there is no water in there - one of the downfalls of a steel frame, but it's worth it. I'm going to go with the B-Stay version, the look is classic, and the ride is reportedly better than the HP version. I'm not worried about the aluminum BB, and I take very good care of my bikes, doing all of the maintenance myself, and I seldom ride in the rain, it's too much work cleaning them! . Besides, of all the current production carbon bikes out there, how many use alluminum BB shells compared to ti? I bet most use aluminum.
