Ohh just reading the specs and 1x8 gives me a lot of options for upgrades eh in the contemporary direction? What is current tooth lowest? What is the max sprocket low I could fit on current derailleur?
. Not necessarily a dealbreaker but just have to get my head around it as I had been thinking 2x, 3x. I suppose there are 2x options for that new looking BB?
the hollowtech BB has just been fitted because I wanted to use up the Shimano ZEE chainset I had sitting in a box , you could equally fit a square taper BB ( its a standard 68mm BB shell) and then fit whatever cranks and chainrings you desire. There is cable routing for a front mech of course but I would say that a 1x drivetrain is a lot lighter than 2x or 3x and you can always go for a wide range rear cassette. Narrow wide chainring + rear mech with clutch means that you wont be losing the chain over bumpy terrain as well. I have converted a dozen or so vintage MTBs to 1x drivetrain and I would say the lack of chain slap and reduced weight are a game changer and I never yet ran out of gears - rear cassettes can be had with up to 11x50 if you have the rear mech to support it.Ohh just reading the specs and 1x8 gives me a lot of options for upgrades eh in the contemporary direction?

With the current BB what is that? Is it different to square taper meaning I would need to replace it to get a classic Sugino Impel on there? As such that means I would be rather committed to the 1x build then
Yes as to the last sentence what is the max dinner plate that the current derailleur would support (and what is max tooth currently)? If it could handle it I would be looking to put something like this on there: https://www.sjscycles.co.uk/cassettes/microshift-acolyte-csh083-8-speed-cassette-1246t/
Microshift acolyte will fit aok , I have used them before - note that the acolyte freewheel and shifter have unique sprocket spacing/cable pull - so you need to pair them up with the acolyte rear mech - unlike the Microshift advent which is shimano backwards compatible. Kids Racing do the keenest pricing on microshift stuff but you do need to match shifter and rear mech if interested in acolyte ( designed for small hands and has extra lightweight shifting). I have used an LX mega drive 44T front ring but any narrow wide of 38 or larger works nicely in my experience. ZEE cranks are 104 BCD 4 bolt pattern btw.
So acolyte would require new shifter?
not sure that modern CUES fits retro freehub - I would stick with something like this if you are looking to replace https://www.sjscycles.co.uk/cassettes/sunrace-csm680-8ay-8-speed-cassette-1142t/ - check the total freehub width and also the pattern of the splines to ensure compatibility with the freehub body you are mounting it to. There are 2 x standard freehub widths - if in doubt check online guides and measure first - note that cassettes for latest 10, 11 speed freehubs don't fit onto 35 mm width HG hubs - as they are designed for wider 37mm freehub - best to measure up before you invest IMHO
