Took the wheel to Wheel Wise Engineering in Horsham (actually Cowfold in East Sussex), where Steve Rolfe has been building wheels for more than 40 years.
Evidently, the rim for my wheel should be set at 22.2 mm from the LHS of the hub (with the final drive sprocket removed) ; my wheel was out by about 6.5 to 7.00 mm. Hopefully, resetting the rim (with new spokes, because the whole wheel had been powder coated and the adjustment nipples therefore unusable) should centralize it – measurement suggests that it should.
Has anyone been able to locate black adjustment nipples to go with black spokes?
Chris.
