Cinema BMX Martinez Stem 48mm - Polished


The Martinez stem is inspired by classic looking top load stems with key improvements in strength and geometry. A 48mm reach gives a responsive feel while the standard 22mm rise can be reduced to just 8mm by inverting the stem. Six oversized Allen key bolts provide plenty of strength and torque and give the stem a classic well-balanced look and feel. Beveled edges and the tapered body profile give the stem a classic yet unique look. Corey Martinez tested and approved.
