Re: the EBB.
The two wedges don’t tighten evenly when you tighten the bolt. It’s not a problem, just something you have to be aware of.
Tighten it then go for a short but hard pedal round the block, at the beginning one of the wedges will be at the correct tightness but the other won’t, leading to creaks and looseness. As you ride the wedges will even up, leaving them both slightly loose.
Now retighten! and you’re golden.
Now it will work without loosening or creaking. Make sure there’s a bunch of grease on all faces of the wedges.
That make sense?

Specwise I was very impressed with mine. Stans rims, pretaped for tubeless, Proper good quality tyres (none of the usual OEM rubbish there).
The only rubbish parts were the cranks and brakes, but then I have those in the bits box anyway.
