dont get trailblades, everyone bends and snaps them, get a rebate, they are pritty light to, only 1.4 or 1.5 kilos, depends if you get 20mm ones or the park (14mm) or the dirt or jump(QR)
i have the QR ones and i have been thinking about getting a BMX hub and putting that on the front, yes it does work and it is lighter then the 20mm's too
