i sincerely doubt that.
a well known suspension servicing website claims that i can buy a replacement Ti spring that weighs 318 grams.
let’s be honest, a bike toy with a claimed weight of 318 grams will probably weigh at least 350 grams.
my steel spring weighs 450ish grams (yes, i’ve weighed it, yes i’ve checked the scales)
so, if i’m happy spending £199 to save 130* grams, then yes, a Ti spring would be worth it.
(*let’s be generous, and give them the benefit of the doubt 🙂 )
do they? – they just look grey to me…
as for weight saving; i just bought some Nukeproof pedals, which have saved me 200grams, for £35.
