Otso Warakin Titanium Frameset

Look out, there’s a new player in the titanium all-road bicycle game and the 2021 Otso Warakin is making a name you might not soon forget.


Product Description

The Otso Warakin Ti is made from the same material and factory that has been the industry standard for decades. Super strong, unexpectedly lightweight and with a classic aesthetic whether matte or glossy, titanium is as real as it gets. 

The Otso Warakin Ti frameset is certain to gain a loyal following, much like it’s siblings in the titanium bike family. Seamless tubing with a primarily matte finish and glossy accents make the corrosion resistant frame timelessly beautiful.

A feature of the Otso Warakin sure to please the incorporation of the patented Tuning Chip on the rear dropout system. The Tuning Chip allows the rider to lengthen or shorten the wheelbase to create a more customizable ride by moving 20mm forward or back at the rear dropout. This not only adjust the wheelbase, but raises or lowers the bottom bracket by 4mm. Set it in the middle for a mid-lever adjustment.

Taking a page from a cross country mountain bike book, the Warakin Ti has an increased top tube length and shorter stem to maintain stack and reach while improving handling capabilities for rougher terrain.

A Lithic carbon fork helps take the buzz out of rougher roads and trails to help you maintain speed and handling. If you need to customize the fork to your tastes, swapping out for a Lauf Grit or other suspension fork is entirely within the realm of possibilities.

Bike packing should be on any Otso Warakin Ti owner’s agenda and several braze-on locations accommodate racks, fenders, frame bags and water bottle cages.
