According to Henry Cole (of motorbike fame) Mk3's are not as collectable or pricy as Mk 2' and much more so than Mk1's. On one of his shows a few days ago there were Choppers with derailleur gears (looked like low end Shimano) and stem lever. Were these an actual Raleigh option?
MK3's were truly awful and caused a dip in Chopper prices. V-brakes, twist grip gear changing, crappy 2-piece saddle, they were WAY off the mark. The more recent MK4's are a pretty good modern execution of a MK2, but you just cannot beat the originals with MK1 being the most desirable over the MK2's
Some notable production variants were:
In the US you could get 10 speed MK1's and also with a high back rest option (check them out, they are crazy high). The shifting is done via a split T-bar shift
In the US they also did a girls MK1 Chopper with no top tube and the shifters were mounted on the side of the stem
You could also get a pink MK2 5 speed in the UK
They brought out a MK2 Special Edition in silver with diecast alloy wheels to celebrate the Queen's Jubilee
Chopper Sprint - MK2 Chopper with bonkers drop handlebars and a truncated saddle with low sissy bar
There is also a one-off gold plated Chopper at Raleigh HQ in Nottingham
Yep the derailleur Choppers had pretty cheap front and rear mechs, they were just kids bikes after all...
