If it only occurs in 8 to 14, that likely rules out a problem specific to the low range planetary gears.  That said, I would expect it to occur in gears 1 to 7 too.  I was specifically thinking that if it only occurred in gears 1-7, that would imply that it was specific to the low range planetary system, but your symptoms confuse me a bit.

If it only occurred once when you shifted from below 11 to above 11, or once back from above to below, that could be from the hub torque limiting components.  For example if your skewer was loose which you already confirmed was not the case. 

One of the planetary gears is only used for gears 1 through 7.  Not for gears 8 through 14.

Does it occur after any shift?  Or does it only occur immediately after shifts from gears 1-7 up to gears 8-14, or back from 8-14 down to gears 1-7?

Gear 11 is direct drive.  Gears 12-14 are overdrive.  Does it only occur when shifting from below gear 11 to above gear 11, or from above gear 11 to below gear 11?

This may be no help at all but is at least free to try: Check rear q/r skewer tension.

Where the cracking is associate with force, it may be the axle working in the dropouts or associated. Similarly, I'd check the machine screws are properly tight on the torque reaction arm.

On the drive side, are you using a slotted/circlip-retained drive sprocket? Those can become a bit worn/loose on the carrier and make a noise on/after shifting.

Best, Dan.

thanks for your advise and support. I'll be removing mudguards for flight packing, which should help with larger tyres too. Not 100% sure of bags as yet. I got a bespoke frame bag from my son for Christmas, which is great. It still lets me use the three bottle cages. I'll use this with either 4 small Ortlieb bags, or two large Ortlieb at rear and one small up front on top the rack?
cheers for now
