The TerraCycle GlideFlex takes Above Seat Steering stem performance and quality to a new level. It's elegant, smooth operation truly puts it in a
class by itself. Walking your bike by the handlebars is no problem with a GlideFlex. Needless to say, there's no lurching or squeaking and the friction stays where you adjust it... all season long, year after year.
If you have a threaded fork on your bike, be sure to also order the Threaded to Threadless Adaptor which allows you to install the GlideFlex atop your fork's steerer tube.
