El Roy combines the classic robust yet forgiving character of chromoly steel meets modern-day long and slack geometry, a match as perfect as mountain biking and post-ride burritos. This new 29" wheel trail slayer was purpose built for silly fun days in the woods, no matter the conditions. Use it as a back-to-the-roots, all-in-one trail slayer, or as that perfect "n+1 bike," on days when the full-suspension bike stays at home in the shed. Named in honor of our favorite post-ride taqueria, the El Roy is overflowing in solid spec choices, all wrapped up with a stout Series 3 double butted and formed CrMo frameset. Grab one of two frame sizes, Regular or Grande, and enjoy the delicious goodness that we've cooked up.

Geometry - Gravity-oriented geometry, with a 63° headtube and 78° seattube angles, 44mm fork offset, and long reach measurements. Investment Cast Dropouts - Custom investment cast CrMo 148x12mm Boost thru-axle dropouts provide strength and stiffness where you need it most.
