I read somewhere on a Moulton website that when Raleigh took over production of Moulton bikes they dropped the suspension fork on a certain model and replaced it with a rigid one. Alex Moulton was not happy about that and warned them it would cause the frame to crack near the head stem, and guess what.....it did.
Raleigh's answer to fix the problem? They made an ugly bolt-on sleeve that covered the problem....out of sight, out of mind?
