A Spicy + Nicy XC Rig

We took the fun loving aggressive Roost Nero Ti and redesigned it into a fast, race-loving XC bike that is advanced, strong, light yet still capable of hitting the stuff that puts a smile on your dial. It is a do it all hardtail that is as happy on gravel fire roads as it is on single track. If adventure is your thing load it up with camping gear and ride away.

The Otho Ti can be used as a Twenty niner or 27-plus, geared or single-speed (with sliding dropout option). This adaptable hardtail can be a single speed racer to a bike packing mule, or anything in between.

Depending on setup and rider skill level, the Otho Ti is a great all-round rig and is very capable on a wide range of terrain from a ride down to the pub, aggressive trail riding to jump lines and all around use.

The unique compliance of our Titanium frame adds beautiful compliance that is hard to describe. The Roost Otho offers less fatigue and better power transfer, whether you’re in the thick of the single trail in and XC race or far out on a bike packing adventure.
