Ok…
A new Anthem frameset with a new Sram xx chainset and all other tried and trusted parts off my old race bike.
It's superb, rides fantastically well but has developed an annoying 'click' like a cable rattling on the frame or fork when going over rough terrain. For instance, riding rough, rooty singletrack the 'click' is apparent on every hit both slow and at speed.
I've packed out all the cables, swapped my wheels over, tightened every bolt, stripped and regreased the headset, fork lock out on/off, pro pedal on/off, pedals clipped in/out and 42/28 ring and still clickity f***ing click… Arghhhh!
What the?????
