@Steve Heywood , it sure would be nice if Shimano gave a list of compatibility. Also, I grumble about manufacturers requiring you to get the newest tool.
The V20c's BB shell's a bit different, using the T47 format. I had barely enough room to tighten it. Also had to buy a tool.

Looks like the clamps that hold the boom to the chainstay have been reengineered somewhat, another reason added to my list to consider a v20c.

CB moved the chain stay clamps inward partly to remove clamping pressure from bb cups not designed for it, and partly to make bb selection less of an issue. I have used the smaller 39mm OD Shimano bb's on three Cruzbikes without issues. I'm sure that Hope unit is nice, but if you haven't ordered it yet, the DA unit should fit and work just as well.

I haven’t done the deal on the hope BB yet so I’ll stick with the DA one.. I am pulling my hair out a little trying to find a socket to fit the 39mm caps or the larger 44mm caps as I have since purchased the Shimano adaptor but the Hollowtech socket I bought off Amazon is too small for the adaptor and too big for the DA caps

BB is now in place and torqued up... Just the crank to fit, front mech and shifters then I'm done..
Is there a torque setting for the new BB / boom clamps or is it like my S40 where you do then hand tight then a quarter of a turn?

It's the same as on your S40.

Thanks… that’s what I did, used the short side of an Allan Key to get them finger tight then nipped them up the quarter turn.. all good

Ok all - I go over this in all of the assembly videos but it seems to me missed way too often: Please DO NOT OVERTIGHTEN your chain stay clamps. Every time I see a broken one it is the same pic - the surfaces are mated completely against one another - that is TOO tight and if you do this - they...
