Hi I am in the process of building up my first bike but I am unsure of the correct headset which fits??? I have been put off by the on one smoothy due to bad reviews online. Does any body know the exact headset I need there’s so many different sizes etc. Also i need a BB I was looking at the xt one which get mixed reviews. I am taking the bike to my local shop to get these fitted but do the headset and BB need to be refaced????? Thanks in advance cheers!!!!

Don’t need facing.
Hope do a headset that fits.
Upper is 44mm zero stack.
Lower is 1.5in standard external. 49.6mm bore.

Cheers brant nice one!!!

Surprised that Brant didn’t mention it 😉 but on ones smoothie mixer works a treat…
