Description

Overview

Chuparosa (Spanish for Hummingbird) is designed to be a versatile trail and all-mountain titanium hardtail.   With a quick but stable geometry, it is at home climbing twisty singletrack or descending fast rocky trail.

The Chuparosa can use 27.5+  x 3.0 up to 29 x 2.4 wheels and tires.  It’s designed to run 120mm up to 140mm forks and the rear dropout spacing is 148mm boost.  The sliding dropouts mean you can run any Paragon style dropouts, making it easy to adapt to singlespeed or to your axle and hub requirements.

The bottom bracket area has received a lot of attention to make it stiff while the rear triangle maintains that legendary Ti compliance and feel.  The stout 44mm downtube is shaped to reduce flex from pedal inputs, and the result is a bike that pedals efficiently, climbs great,  and accelerates into a smooth comfortable ride.

The Chuparosa is happy on 29″ tires as a fast trail bike that would give a good account of itself in an XC race.  But, it’s sweet spot is on 27.5+ tires with longer travel, running through rocks, roots, and technical singletrack.

It’s a bikepacker, too, with a front triangle able to accommodate a modest frame bag and a lower downtube bottle mount.  The prototype has bikepacked hundreds of miles of the Arizona Trail so far in testing, and has proven to be a fun and energy-saving pack mule.

Everybody talks about that one bike, “If I could only have one…”  This might be that one!
