EVO, the lower 1.5 bearing is this one:hi guys, right I need a little help in the selection of my headset. I know the official one is an FSA orbit No. 42/ACB-1, 1 1/8" but the uk distributor silverfish dont have any. Can anyone provide me with the actual bearing sizes and angles as I cant get hold of the correct headset soon enough and would like to just build one up. The standard FSA 42 does not have the -1 after the ACB in the description so any idea what this is please people? HELP I want to ride this bike ASAP!
*EDIT*
The part I listed from FSA, although similar, is NOT what you need as it had a 36x45 degree chamfer. The lower 1.5 bearing is of the non-chamfered variety:

The FSA P/N is: MR069
*EDIT*
The upper 1 1/8th (1.25inch) bearing is a 45x45 degree, 41.8x30.9x8.0mm (ODxIDxThickness)
This is also known as an 870E-RS bearing
