Weekend should get some more time for installation and then put the whole beastly Mammoth back of the bathroom scales.

Ooooh, where from and how much?

I remember losing nearly a kilo just from removing the tubes at my first (failed) attempt at Ghetto Tubeless

Not New unfortunately. From a wanted ad on rotorburn.

It’s just nuts how heavy the tyres, and other parts, are.

Updates. Finally got some round tuits.

Somewhere in the vicinity of 4.5kg lighter. Still no lightweight at 18.8kg but it’s a lot better than before.

Parts:
Drillium rims. Duct tape rim strips. Saving over 400g of holes and swarf and not including what went straight into the vacuum cleaner.
Tyres: Second hand Vee 8. $30. Saving: 2.8kg (one original tyre's worth)
Tubes: Still there, might go tubeless, or get some lighter tubes.
Seatpost: eBay alloy. $16. Saving: 84g. Not much, but the existing one was a tad short for me.
Stem and Bars (not in pic): Alloy. $0 (parts bin). Saving 307g. Originally I was only going to replace the bars and got stopped because the stock stem takes 22.2mm BMX sized bars. Fortunately I found another 1-1/8 quill stem in my parts bin so the alloy 25.4mm MTB bars got a second try.
Crankset: Shimano Alloy + widgit 32tooth ring. $0. Savings approx 550g - forgot to weigh it before installation.
Cog: Switched gearing to make it a bit easier, 18tooth. Gone from 36-20 to 32-18.
Chain: switched to lightly used XTR 9spd from original SS. saving ??
Saddle: weighed the same as the potential replacement, so left the original.
Pedals: original
Removed: kickstand and chain guard. Saving: 422g.

Better remove those reflectors too.

I've now ridden the Mammoth twice since the Jenny Craig process. It seems a lot easier to spin up to speed now, but that speed is ultimately a little less than before. It's also easier to climb the local hills. The chain got a bit loose so I mustn't have tightened the nuts properly. Rode it to work this morning, said I'd never ride it to work again after the first time, but it's got a higher saddle now. Don't think I'll do it again!
