2022 Reign E+2 headset replacement bearings

[Kevjob51]

I am having alot of trouble sourcing replacement headset bearings here in US. Giant store closed and cant seem to get any help from Giant retailers.

The bearing numbers I have are

upper TH MR122 1-1/8" (36 X 45) G2

lower TH MR229 1.8" (36 X 45) H2

I have found a TH MMR229 1.8 (36x45) F2 would that work in place of the H2?

Anyone know of a replacement headset that I could install if I cant find replacement bearings?

Trek has this one for rail which also uses super taper 1.8" fork like my zeb but it is G1 not H2 and I do not now the difference from F2 to G1 to H2 bearings.

Replace the whole headset, it's awful with steel cups and a (usually) undersized taper lock which is made from plastic meaning you'll never stop the creaking.

You need a ZS66/40 lower & a ZS44 upper.

Superstar Components do a dedicated ZS66/40 lower. Hope make a ZS66/48 and a crown race adaptor to make it fit the 1.5" fork. I'm not sure if either are available in the US.
