Because Raleigh could make decent bikes ,but often opted for laziness.

It reminds me if some of the terrible engineering by Raleigh. I helped some user testing of the Raleigh Burner BMX(1990's) with stickers over the Raleigh name to conceal its idenitiy. All of the bike were handled back with several broken parts on them after only a weeks trail, by mild mannered racers,not stunt riders. Problems included alloy bars that were dangerously weak, and the frame Downtube was flattened then welded underneath the bottom bracket, instead of meeting it as a full tube. Despite the results of this testing, the same bikes went into production unchanged! I remember a nextdoor neigbour asking me "aren't the new Raliegh BMX range great!", he worked at Raleigh, and he did not seem to like my race quality imported BMX bike. Ignorance is bliss!

Great memories, and the factories was in my home town of Nottingham, but not every thing from Raleigh was great!
