2022 Santa Cruz Megatower 2

41mm upper and 52mm lower integrated headset cups.

The geometry is based on a 160mm fork with a 42mm or 44mm offset. You shouldn't have less travel because the BB will get too low. But you can go up to 180mm fork.

This bike is compatible with all shocks on the market. Anything from Fox to Rockshox.

You should try both. Start in high to make the bike more agile and easy to get used to. If the terrain is steep, switch to low. That will lower the BB and slacken the head angle. The leverage curve of the suspension is also more progressive. All of those changes will make you feel like you're seated further down. It's all easy to change whenever you need.

36t or smaller chainring with a 52mm chainline.

This bike comes in the short position. The brake mount is post-mount 180. So you can add any adaptor for your chosen rotor size. Or none if you want 180. This bike also has a special brake adaptor to adjust to the long setting. That only works with 200mm or large rotors. If you're using 203, use the included 1.5mm spacers between your caliper and the bracket. If you're using 200, put the spaces above the caliper. When you've changed the adaptor, install the long derailleur hanger, then flip the chip around in the non-drive dropout. There's a retaining set-screw in the chip. Loosen it to remove it, then tighten it when the chip is back on.
