You're really getting stuck in! I'm ashamed to say I have no zero knowledge/experience of anything you've mentioned except the remap; one of mine had a Hirsch remap (and no other mods) and it wasn't ideal. The boost spiked massively and then dropped away sharply so it drove a bit like a diesel and loved to taunt the traction control/eat tyres.

In trying to avoid GXP bottom bearing issues (which apparently don't exist anymore?) I've run into another issue:
Frame: 68mm BSA
BB: Ultegra HT2 + single sided GXP adaptor (i.e. not a double sided Hope adaptor) on the inside of the NDS bearing (as per instructions).
Crank: Sram Apex GXPIssue: There doesn't seem to be enough axle length coming through the NDS cup for the crank to be tightened without on the bearing. The bearing either spins with the play in the NDS crank, or starts binding way before the NDS crank bolt is sufficiently torqued to remove play.
The only way it torques-up and spins is with the adaptor on the outside of the NDS bearing, but it thought rules were rules..?
TL;DR: GXP to HT2 adaptor only works when installed in reverse. Am I compromising anything by leaving it?
Axle length with adaptor:
Crank tightened up completely:
Axle length with adaptor and NDS bearing:
Axle length with adaptor assembled in reverse:
Installed with adaptor in reverse:
Thanks!

To update this thread: Tredz are still useless.
Just been sent a damaged rim, that someone clearly attempted to lace up before/after dropping it and gouging the metal. Luckily their service is highly efficient; looking forward to my email being answered sometime in November and the replacement rim arriving mid-2021.
