New Gruppo on older bikes

put modern groupset on it, no point keeping the old one (unless it work perfectly well for what you want it for).

(90s) 8 speed Chorus cassette with Chorus hubs and Amboriso rims - 1800g.

(2010) 10 speed Centaur cassette with Amboriso hubs and Mavic Open Pro rims - 1400g.

modern stuff make a huge difference.

Apologies for a derail - but Ed where is that picture from - as my 2yr old daughter needs that trike!!
