Found the answer myself, standard BB86 / PF41, so a 41mm ID.

When Colnago created the C60, the company implemented a new bottom bracket design dubbed ThreadFit82.5. Comprising a pair of threaded rings that secure an aluminium shell within the carbon fibre bottom bracket lug, ThreadFit82.5 has an internal diameter of 41mm that is directly compatible with all BB86 hardware. Threadfit82.5 remains a feature for some of Colnago’s current framesets, including the new C64.

Hi all, does anybody know how much the original Colnago cups weight?
Trying to compare how much the combination of original cups + pressfit bb weights compared to Ceramicspeed solution (84g). Thank you.
28g for the pair
Thank you. As shimano standard BB92 is like 55g, its basically the same weight just to put there cheap shimano dura ace press fit bb instead of ceramic speed..
Does ceramic speed have any other advantage (besides highly discussed advantage of ceramic ball bearings)? I mean is it better for maintance/durability/no creeking to screw there ceramic speed or Colnago cups with Shimano press fit bb is similar reliability?
Thanks so much!
I am running a CS (T-45) in my V2R and it has 17000km on it now with no issues at this point. I have removed the seals to clean out the old grease and pack with fresh new grease a couple times now. I did this without removing the brgings from the BB, just removed the crank to have access to pick out the seals. The only downfall with this particular BB is the cheap plastic tool they supply as its good for one installation/removal and I cant seem to find any steel tools for the T-45 just yet. I did however purchase a Shimano BB86 that I can use with the other set of cups that come with the frame and I have the steel tool for those cups. So if anything happens to the T-45 I have the BB86 to install until I figure out what it is I am going to do with T45. At this point the CS BB has been better than what I expected for ceramic brgings so I will continue to run them as long as possible. Hopefully a proper tool becomes available soon.

Also for reference Abbey tools make a tool for the original cups if you want to use them rather than CS cups.

I've been very happy with the CS T45 on my C60 as well. But I always worry the plastic tool came with the bb isn't strong enough when I need to remove the bb. One thing I noticed is on the tool is says 'T45-T47' and makes me wonder if T47 tool from other companies like Parktook, CK, Praxis etc would work. The patterns look similar between CS T45 and standard T47 cup, at least in the pictures. Does anyone know?

I purchased the Abbey tool for my BB86 and its a nicely machined work of art. I wasnt sure the T47 would work but good to know, thanks corky.
Park T-47 BB tool ordered and on the way.

Hi Bikeboy1tr

I was intrigued reading your post. Can I please clarify;

- so long as periodic maintenance (removing seals and repacking grease) of the BB is undertaken, you have managed to run the same BB for 17,000km?
- are you able to please provide a high level overview of how you undertake this maintenance? Is it a case of changing out the white grease that is visible in this pic below (the BB bearing seal cap is lifted off slightly, revealing the grease) or are you referring to greasing something else?

Many thanks
Mike

Hello Colnago C64 owners,

Since 2 weeks Iam the proud owner of a C64 in colorscheme PJWI! I noticed to some of the decals on matt part are a bit cracked. In the photo if you look closely at the C you see a minor crack. At the 4 a part of the sticker is missing. Is this something to worry about or just part of the handmade method and decals are just likely to fade of a little? Please let me know!

Those are not decals/stickers, the lettering on these frames is stencilled on with several layers of paint. In your case it looks like something has caught the edge of the paint, or excessive pressure been applied. A clamp maybe?
