Sebastian Karimian, a custom bike builder and fabricator from London, UK, just made “the most titanium bike in the world,” which weighs in at just 17 pounds, complete with a Ti water bottle, fenders, grips, and more. Check it out here…

We recently stumbled upon a Facebook post from London, UK-based Sebastian Karimian, who just finished building the most titanium hybrid/mountain bike in the world, setting an unofficial record in the process. There’s not a whole lot of information available, but Sebastian provided a list of every titanium component on the build, which you can dig into below.

While there are a staggering number of titanium parts, he chose not to use titanium spokes due to their cornering performance, or a titanium saddle, for that matter, because he still wanted the bike to be comfortable. If someone goes after his record he said he could easily replace those with titanium versions. Although the build is made up of a lot of unbranded, custom titanium parts, we did spot some titanium valves from our friends at Terske being used.
