At least it rules that out. Only other thing I can suggest is maybe taking the cranks off the bike and seeing if the wobble is in the cranks or whether its the bottom bracket.
On the Raceface cranks if you look at the right hand crank there is an 8mm crank bolt that tightens the rh crank into the axle. There is also a 10mm crank puller cap that sits around the 8mm bolt so to tighten the 8mm bolt you go through the 10mm opening.
Wasn’t expecting much from the Maida Vale concert after the performance on Later but was surprised how good they sounded and Black Francis still has the lungs.
