PROMAX IG-45 HEADSET

The IG-45 integrated headset features an aluminum cap, bearing cover and crown race with super-smooth rolling, precision 45×45 bearings.

NOTE: The 1" Promax Integrated Headsets use the same size bearing as the 1 1/8" headsets; the primary difference is that the top cover and the fork race have a 1" opening so that you can mount this headset in a frame with a 1 1/8" headtube and run a 1" steer-tube fork
