Frame is an On-one 456 Ti, bottom bracket is Hope (but have also tried Shimano).
B/b is installed using Finishline Ti prep, b/b threads are de-greased and well cleaned out before installation. Tighten everything up nicely, install chain rings, all ring bolts tight and crank bolt.
I can then ride with no problems, no creaks from the b/b. Happy days...
Then I take the little one out in the Chariot. After a couple of rides of admittedly tugging a bit harder on the cranks the b/b starts creaking. Unhitch the Chariot and the creak remains. The b/b still feels tight, as are all the bolts. From this point on creak only gets worse until it's unbearable.
Nothing to do now except, take out the b/b and go back to step 1 which stops the creak but only until I've been out pulling the Chariot again.
Please help, what am I missing? The noise is definitely from the b/b as after I disassemble/clean/ti-prep it goes away.
Ta for help from anyone.
