Ultralight Terske titanium 44mm valve stems, anodized in violet.

Why titanium for tubeless valve stems?  While we love the sort of upgrades that shave weight and add a bit of character to our builds, sometimes those upgrades come with downsides.  In the case of lightweight aluminum tubeless valve stems, that weight savings comes with a serious reduction in strength- as anyone who has snapped a valve stem while frantically pumping mid-race (or hanging their bike from a hook in the garage) will attest.

So we propose a compromise: give us back a gram and we'll give you a tubeless valve stem nearly four times as strong as the alternative.
