as far as i'm aware... HT2 is an external BB.
HT1 is internal i think.

Do you have pics?

sorry its a press fit bottom bracket. is it just a case of knocking it out with a drift? and pressing by hand?

Stab in the dark that it may be a bb30 type BB?

from a quick read... it looks like its a BB90 bottom bracket (or similar).. so yeah a press fit.

The park tools link ^ shows how to uninstall the press fit bb

Park tool BBT-90 to remove the bearings; you may need adaptor bushings (in a piece of cunning, the BBT-39 BB30 bearing removal tool is supplied with both BB30 & BB92 press bushings...) for the headset press.
