Sometimes it happens. Extralite make the lightest alustems what I know and have the best looking lightweight hubs on the market. But some weightweenieparts they missed. Like their seatpost, their old one was pretty heavy and costed much, compared to KCNC Ti Pro-Lite. But now it changes, if you have the right frame:
Classy as always from Extralite but it’s light too. 250mm is 99g and 350mm is 138g. Then the sad part, only available for 31,6mm. Otherwise I would have wanted one. Nice clamp though:
Price is 199€ from Dulight. Not that high if you think of the weight.
