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。 Rock-solid stem and faceplate made from 3D forged 6061 aluminum, a combination proven to increase strength and reduce weight. The ‘forged’ method of manufacturing is significantly stronger than ‘cast’ but requires less material, resulting in a stiffer and lighter stem. Because correct stem length is vital for a comfortable bike position and good handling, the CLS stem comes in eight sizes, from 60mm up to 120mm. Easily flips to give a 5° rise or drop depending on your aerodynamic ambitions. SCM-435 steel bolts adds further strength while providing a secure fit. Fits 28.6mm steerers and 31.8mm bar clamps. Weighs 110g.
