ergotec Up & Down Turn Adjustable Stem Riser

The Up & Down Turn is an adjustable steerer tube extension that allows you to turn the handlebars by 90° independently of the height adjustment to save space when transporting the bike.

Depending on the version, you can achieve a comfortable height gain of up to 150 millimetres with this stem. Ideal for hybrid and city riders who prefer an upright sitting position and appreciate a high degree of flexibility when transporting bikes on the train, in the car or on the rear rack.

The steerer tube does not need to be machined to fit the Up & Down Turn extension and it can be removed at any time.
