I only use 2.2 tyres and only use 50ml of sealant so I save more like 140 grams.

As many people have stated, it is not for the weight saving – that is a side benefit.

Stans sealant isn’t 1g for 1ml. 120ml is about 90g. I was surprised, I thought it’d be heavier than water.

Good post though otherwise and highlights why people get different results- on a bike with minions (assuming I was riding it like it needs minions) I’d have to run too high pressure to make a conti light work. So I’d have either a big tradeoff of performance, or of weight. I used specialized standards when I use tubes, they’re about 220g IIRC and that works alright.

But I’d only put 90ml of sealant in ’em too.
