Mountain Sizing Information

For an approximate calculation of your correct frame size, measure your inseam in inches, crotch to floor in bare feet, and subtract 16 inches.

When in doubt, choose a smaller frame size, especially if your legs are long in proportion to your upper body.

Frame sizes are measured from the center of the bottom bracket spindle to the center of the top tube at the point where it intersects the seat tube.

"Nominal" top tube lengths are measured as if the tube were horizontal (parallel with the ground). The measurement is taken from the center of the head tube/top tube intersection to the centerline of the seat tube, extended to meet the imaginary horizontal horizon drawn across from the head tube.

Frame sizes for: Mountain, XLM, Echo, Fat Ti, Fat Beat

0. Front derailleur clamp: 1 1/4-in. on 13.5 Mountain 1 3/8-in. on all other frames
1. Seatpost: 27.2 mm
2. Dropouts have threaded eyelets
3. Top tube cable rounting standard; down tube cable routing is optional
4. Suspension-adjusted geometry is compatible with standard aftermarket suspension forks
5. Steerer lengths calculated with a 46-mm stack height; measure all parts before cutting the steerer tube
6. Frame weight does not include fork or bottom bracket; all weights approximate

All models have sloping top tubes.
Standover heights may vary with tire profile
Racks may not be used with XLM frames

Road Sizing Information

For an approximate calculation of your correct frame size, measure your inseam in centimeters, crotch to floor in bare feet, and multiply by 66 percent.

Frame sizes are measured from the center of the bottom bracket spindle to the center of the top tube at the seat post binder (not to the top of the seat tube extension).

All other measurements are center-to-center.

For center-to-center frame sizing, subtract 1.5 centimeters from the Merlin frame sizes listed in the specification charts.
