I have a Ritchey WCS press fit (semi) 1-1/8 headset (i think its this one Linky ). Its running rough but i am having a really hard time finding out what bearings it uses as i am not swapping the cups as they seem fine. The bearings are currently stuck in the frame and i reckon once i have knocked them out the info on the side of the bearing wont be readable due to corrosion. Using Cane Creek finder it seems its upper fit is zs44/28.6 and lower fit zs44/30 but no other helpful info for the bearing dimensions, anybody able to point me in the right direction? Bike is a Scott CR1 2012
