Just built up a Giant Reign (1st generation) using a frame donated by a mate, which he bought whilst working in states. The frame was in almost new condition so I dont think its seen much use. I’m coming from a Blur Classic with fox floar r rear shock..
However, now its built I’m getting a harsh ride from the rear over rocks etc, and when I cycle the rear suspension its making a knocking noise which I can also feel through the saddle. I’ve tried cycling the suspension whilst touching each of the pivots/bearings/shock bushings but everything feels tight (always found which bearing/bush had failed on Blur this way)
This makes me think its the rear shock thats the problem (although I may be wrong). The rear shock is a Manitou Swinger Air 3 way with SPV. I’ve set the sag correctly (200lbs in weight so around 140psi in shock), and played around with SPV pressures from 50psi to 175psi but still I get the harsh knock over certain type of terrain together with this knocking sound?
If I stand on the pedals and squish the suspension slowly its feels quite plush, however if I cycle the suspension quickly by pushing down on the pedals or dropping my arse on saddle it knocks?
Any ideas or advice appecated, as this is spoiling what is otherwise a very satisfying build!
Many thanks
