    2018 headset bearings (Thunderbolt)

    Who knows the specs/link to headset bearings for the new Carbon 2018 Thunderbolts? They should be the same as the Altitude as well. I donít wanna spend $70 to get a whole new headset, when all I need is just the lower bearing. Itís a FSA ORBIT no. 57e that comes with the bike.

    Any help is appreciated!

    The lower bearing is an MR019, 40mm ID, 51.8mm OD and 7.5mm tall, with a 36deg inner chamfer and 45 degree outer chamfer. They are still fairly hard to find as a bearing by itself.
