You’ll need a seatclamp - the seat tube is 29.8mm outside diameter at the top, but clamps labelled 30mm will be fine too. The seat tube butts down to 28.6mm outside at the bottom, for your front mech, and inside the frame takes a 27.2mm seatpost. BB is 68mm shell. Front mech is top pull. Brakes are international standard. Headset is inch and an eighth. All the bits off a standard inbred will fit.
