Shame that they were asset stripped in the 90s. At least some people recognised what was there – pity that it was a Taiwanese company, at least it renamed itself Sunrace Sturmey Archer in recognition when they bought sturmey Archer in its entirety before it was split up in auction.

Not convinced the Special Products stuff was much cop tbh.
I worked in a bike shop at the time of the Dyna-tech frames and even bought a road frame myself – after a visit to their factory and being convinced they new what they were doing.
I would wager that every single Dyna-tech frame we sold came back to us broken, both road and mtb. (My family broke one of each plus both their warranty replacements.)
The chainstays would go in the main or, downtubes split by the gear lever bosses on road bikes.
Sorry state of affairs.
I guess that's why they ditched the name (and bonding process,) and started M-Trax.

Raleigh nosed dived but are back (like GT but somebody else owns them?)
They import and sell loads of bike accessories and cheap mudguards.

They have some nice road carbon jobbies but not exactly are bargains compared to Boardman. I would buy a Raleigh if it was the right price but for £2000? hmmm maybe not.
