Hi IT,
Thank you for this suggestion - in fact, I'd already come across Neil Gunton's web pages, which I think are excellent.
Unfortunately, I can't apply his solution as my front rack is a Blackburn Custom LowRider (hoopless) type. I had thought about using a Minoura Space Grip on the fork, but am not sure whether this could be successfully fitted.
Any other ideas will be very welcome!
Best wishes,
Jeremy
