This rider had two bikes that they really enjoyed riding but wished they could be combined into one. Going with a custom full suspension gives that ability and therefore this frame was designed and built!
One main goal of this bike was to ensure that the bike pedalled uphill amazingly well, while at the same time being very active and progressive on the downhills. To achieve this we went with a Horst-Link 4 bar linkage design which gives the ability to fine tune the balance between climbing and descending.
The frame was designed around the use of 29x2.6" tires with the ability to go 27.5x3.0". Front travel was set at 150mm, and the rear at 140mm.
