CONTROLTECH品牌是1989年由一群單車愛好者在美國西雅圖創立,致力於研並提供騎乘者最好的產品。 1990年專注登山車相關的零配件,2000年後延伸產品線至公路車、計時車及三鐵車的領域。 Forged from 7075 aluminum, which uses zinc as the primary alloying element. This combination creates a stem that is strong, durable and low in weight. Correct stem length is vital for comfortable bike position and good handling. That’s why the SLA Stem comes in seven sizes, from 70mm up to 130mm. Easily flips to give a 5° rise or drop depending on your aerodynamic ambitions. Stainless steel bolts. Fits 28.6mm steerers and 31.8mm bar clamps.
