Couple of things if anybody can assist.First how can I determine what seatpost I need ? Is it as simple as measuring,same goes for the downturn as need to it band on front mechanism.Also when building up do I need a torque wrench or is hand tight ok ? Thanks in advance
It's a onix which are now beacon bikes.
That's it thanks !If it's this frame:
Seatpost Onix UL1 31.6mm
FD version best determined by pi x caliper measurement of Seat tube outside diameter, where band-on will clamp.
