Apart from the weight difference 30g which I am not bothered about. What are the different characteristics between the saddles? I'm not getting on with my new charge spoon and need a new saddle but don't want to fork out an extra 40 quid for 30g's. Comfort is paramount. It seems to be a popular saddle.
I've got a fizik gobi I'd sell for £27posted. superb condition, no rips etc. PM me if interested
I have 2 normal gobis and 1 xm , can't tell any difference despite them being on 3 bikes , the xm has a better finish
I've got the Kium but haven't ridden the Manganese.
The Kium is supposed to give titanium levels of bump absorbtion for less weight.
Mine is the most comfortable saddle I've ever used. No unpleasant pressure points, no numbness - all good.
Forgot to add that they are so comfortable , I bought one because of a magazine rating, I remember it described
As hammock like, they are worth the money
