The technologies demonstrated in TES are attitude and orbit control system, high torque reaction wheels, new reaction control system with optimised thrusters and a single propellant tank, light weight spacecraft structure, solid state recorder, X-band phased array antenna, improved satellite positioning system, miniaturised TTC and power system and, two-mirror-on-axis camera optics.

Lower ball joints are sometimes larger and may wear out faster, because the fore and aft loads, primarily due to braking, are higher at the bottom ball joint . ( Torque reaction and drag add at the bottom joint, and partly cancel at the top joint . ) Also, lateral cornering loads are higher at the bottom joint.

As with all hub gears, there is a torque reaction that must be countered if the internals are not to rotate, and this is routed to the bicycle s frame by means of specially designed wheel dropout slots ( OEM versions ), or a torque bar bolted to the frame ( EX ) or the disc brake mount ( DB ).
