Choosing a Clamp Position

The stem clamp can be set up for a higher or lower bar position to accommodate a wide range of body proportions. The lower position is a good place to start for anyone under 5’8″ (172 cm), although anyone who is above this height and has shorter arms or torso may also want to use the lower clamp position to allow for a shorter reach distance.

Measure reach as the distance from the center of the handlebars back to the center of the bottom bracket (A) and stack as the height from the bottom bracket to the center of the bars (B). Take measurements from an outdoor bike that you want to use to set your fit on the SB20, then match those numbers to the tables below to determine the best clamp position for you.

*When using the lower clamp position, add 8 cm to height and 4.6 cm to the reach to use the laser-etched numbers on the height and fore/aft sliders.
