I have a clicking noise from my Hope Evo crankset that only manifests under heavy load. I have ruked out every other possible cause including servicing rear shock, new frame bearings, shock bushings, rear hub bearings, rear axle, stripped and regreased/cleaned the crank/BB, tightened spider etc etc. Noise not apparent if I put a different crank on.
Anyone have any experience of this?
Always either the ring to arm interface or the BB bearings.
If you're really unlucky it's the axle.
Pedals - remove, clean, regrease, refit, torque
Having ruled that out, the same procedure for the chainring/spider - they need to be real tight.
And yeah, have a feel of the bearings while the crank is out.
Try removing, greasing and reinstalling your pedals to the right torque. The torque is quite a lot higher than you'd think. I had the same clicking under load and like you tried bolts, spiders, bottom brackets. It was the DS pedal.
It drove me mad, @daffy - I was sure it was bearings, had takes just about everything else apart, bearings, cranks, direct lount ring, seatpost, saddle - finally found it was just the pedals
Should have mentioned, tried 2 new brand new sets of pedals greased and torqued to correct value not that.Also as stated above the noise stops when I put my old Shimano cranks on.
As mentioned in original post I have stripped, regreaed and re torqued the pedal chainring interface.
Bearings in BB absolutely smooth and inly a few months old so not that either.
Have you had a look on the back of the cranks to see if there's a mark? Might be hitting the frame with flex under load.
Had this and it was the spider locknut. Came loose twice despite loctite. Got rid of them after that.
Is it a Hope BB? I ask as I had similar noise when I moved from Shimano to Hope BB.
Turned out that I'd not tightened the centre bolt enough that pulls the crank arm onto the crank axle. A quick few turns of that sorted my clicking.
None of the above!
Spider tight
Crank cinched up correctly
Crank completely clear of frame
Add more pre-load and see if it goes away

Do you mean on the collar?
Yeah. Tighten that a "bit" more.
My non- Evo was creaking like a bastard. Tried all sorts.
Moar preload sorted it.
Wasn’t the preload. Gave up in the end, put my old XTR crank/BB on and the clicking miraculously stopped.
chain quick link on upside down?
No, that’s a schoolboy error I have not made for many years! Besides an upside down quick link makes the chain jump rather than the crank click.
