United Mothership Frame


This is what United have to say about the anticipated United Mothership Frame, Nathan Williams signature frame.

United Mothership Frame


This is what United have to say about the anticipated United Mothership Frame, Nathan Williams signature frame.


When working on this frame strength and durability were always at the top of our list, with the way Nathan rides constantly trying to lighten up a frame just didn’t make sense. What we have ended up with here is the strongest frame we have produced by thickening up key stress areas, adding custom ovalised downtubes and chain stays for dent resistance, an all new gusset area combined with a longer headtube to provide a stronger junction, and then by trimming down areas that can be done so safely, have come up with a what we feel is a perfect strength – weight ratio.



Dent resistant oval downtube. New re-designed gusset with stamped logos. Lower headtube for better weld area junction. Tapered top tube and seat stays. Dent resistant offset thickness chain stays. New chainstay shape with clearance for tyres up to 2.3" Stand over height 8.7" (centre BB to centre TT)

Top Tube:

20.5", 20.8" and 21"


13.75" to centre back end (13.6" slammed)


75 degrees Headtube


Mid, Height-11.8’




Ultra Compact 5mm, with CNC machined cut outs


2.12kg (4.66lbs) approx for the 21.25 Inch size, without pedals (built). (PLEASE NOTE: Weight is approximate and is provided by Evans Cycles as a guide only, actual weight may vary due to manufacturing processes and other factors)

Extra Features:
