Which came first, the chicken or the... doping scandal?
Is that why they never really took off, or was it coz they're bricks?swampy1970 said:Look Ergo stem....... It's not much fun when you find the bars about 50cm lower than what they were a split second ago... and that was with me tightening the damn bolts to the specified torque too!
