Our Surron Light Bee headset press has two functions; first it can be used to press the angular contact headset bearing races into their cups, and secondly, it can be used to press the bearing race/cup assembly into the LightBee's headtube.
The set comprises of a pair of drifts that mate together to guarantee alignment of the bearing race and the cup. The female drift has a taper that matches the taper of the bearing race.
The drifts are supplied with our M12 (12mm diameter) headset press threaded rod, T-bar handles and thrust bearings. The threaded rod is made from stainless steel while the handles and drifts are 6082-T6 aluminium.
The LightBee's headset is assembled in the following order:
- First press the bearing races into both cups. The tapered end of the female drift should fit the taper of the bearing race, the male drift is then used to press the cup onto the bearing race.
- Next, press the larger cup/bearing race into the 55mm ID opening at the bottom of the frame's headtube; the male press drift fits into the lower cup, while the female press drift goes against the 44mm ID upper end of the headtube.
- Finally, press the smaller upper cup/bearing race into frame; at this stage it doesn't matter which drift is used with the top cup and which with the bottom.




To confirm suitability; the bearings that this press are intended to be used with have an outside diameter of 47mm. The lower end of the frame's headtube has an inside diameter of 55mm while the upper end has an inside diameter of 44mm. If in doubt, please contact us and we will be happy to discuss!
