is 200grams the ultimate limit for road bars?? Seems carbon and Aluminium compete on an equal footing in terms of weight.. oF course carbon bars are quite expensive and at best you can save 5-10 grams.

Also, problems with scoring and sratching carbon bars. Has anyone tried titanium or any other metal alloys??

Opinions lads and lasses?

am surprised no none has considered using stabilised alu alloys using semi exotics such as niobium, titanium, mo or other such transitories..greatly enhanced properties..less expensive than Ti based..any thoughts??

when i ws into MTB'ing years a go I saw a lithium alloy mtb frame..can't remember exactly who made it.. also there was on made with a element that is toxic as a dust (think it was beryllium).

both seem a little exotic but the precedent is there for using more exotic alloys in bike construction.

I've seen some exotic alloys that contain traces of Na, K and Li.
Would these be suitable in very wet conditions??

I think you will find most metals carry traces of common elements i.e sodium, potassium etc. Doubt if wet weather would have a detrimental effect though.

what if Na, K and Li were present in larger amounts. Say up to 35-50%?
Mechanically if alloyed with bismuth, lowC fe and tits could be a possibility?
