JensonUsa, UniversalCycles and Beyond have the pike coil 426. They say with a steel steerer tube. Is the steel stronger than the alloy steerer and that's why it's on the coil. I don't see a 454 coil anywhere. On beyond bikes it says a steel steerer tube and 4130 chromoly upper tube, what does that mean? Iam bouncing between coil and air. Not sure if air will handle as much punishment as a coil. On rockshox site it says for the 454 upgrade over the 426 is alloy steerer and hollow crown but on the 454 specs it shows hollow crown, does anyone know what it is?
