RIDER SIZE

The frame of the ULTRA high-racer is designed in a single
adjustable size, capable of accommodating both taller
cyclists and those of shorter stature. The reference
measurement ‘X-seam’ is the length of the legs from the
heels to the glutes. Take your measurement barefoot and
with legs together.

Maximum X-Seam

The maximum boom length is suitable for cyclists with an
X-seam of 1250 mm when the seat center is aligned with
the seat-post plates. The ULTRA frameset can
accommodate taller riders (X-seam greater than 1250 mm)
by moving the seat backward, positioning the seat center
behind the seat-post plate. The seat center corresponds to
the lowest point of the seat.

Minimum X-Seam

The minimum required X-seam measurement is 1010 mm
when the seat center is aligned with the seat-post plates.
The ULTRA frameset can accommodate smaller riders
(X-seam less than 1010 mm) by positioning the seat
further forward.
