Well it is lighter and cheaper, yes.
The thing is though, I don't really like the look of it.
I miss the spider that wraps around the crank arms.
I might get a new 104mm spider from North Shore Billet. Expensive though.
Either than or 94mm chainring.

I got a nice price on a few lightweight nos headsets, KCNC & crank brothers (like 30 to 40 euros).
So I may or may not fit one of those.
May as well go for an attempt at the title of "world's lightest mountain cycle shockwave 9.5".

This has been ordered.
Reasonably expensive for what it is, but such is life.
I might just hang on to the 94mm spider in case I want to downsize the front chainring one day.
Also thought about getting a direct mount chainring instead, which would have been cheaper and no doubt lighter, but as previously stated, don't really like the look of them (or how they attach, I like the more sculpted/moulded look where they blend into the crank arms a bit). So too new for my liking.

This arrived today.
Just some cheapy SRAM/truvativ GXP cups (only £25).
Was not able to find a black version in 83mm width, only silver.
So went with a black 100mm fat version instead.
Seeing as the BB shell does not seem to have any open entry points, I will forgo the centre sleeve, bugger it.
Well it won't fit anyway. Of course, that was the plan.
I'm now selling that separately here.
The new crank/BB combination looks to save around 300 grams of weight (well, mass) overall.
I thought it would be somewhat more than that actually. Oh well.

Well, it appears I ballsed up.
I took off the existing crankset + BB. Nothing untoward.
Then as I was inspecting/cleaning the old BB in order to photograph and sell,
I noticed that it looked shorter than I expected. Or rather, normal size.
Then reading "73mm" on the shell (centre sleeve) I was like "funny, shouldn't that read 83mm?"
Dashed over to measure the shell width and it is indeed 73mm not 83mm.
I could have sworn it was 83mm.
Lesson learned kids, don't trust your memory to these things.
I thought I could remember all the sizes of all the bits on all my bikes. Apparently not.
Oh well.
I might be able to put some spacers on either side (or something).

You could just buy a 73mm centre tube? https://www.ebay.co.uk/itm/303139898304
