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。 10mm clamp offset is ideal for lengthening/slackening short frames and steep seat angles. Low weight – just 242g – reduces inertia and makes your bike easier to flick from side to side. 7075 aluminum is alloyed with zinc and magnesium to create a high-strength yet low density material ideal for tough off-road use. Stainless steel hardware holds saddles rock solid. Comes in three diameters: 27.2mm, 30.9mm and 31.6mm. Available in two lengths: 350mm and 400mm – to suit all frame and rider sizes.
