Often overlooked in favour of the lighter titanium models, Raleigh made some really nice bonded steel Dynatech frames during the late eighties and early nineties.

The innovation made by Raleigh for this range of bikes was the bonding together of the main tubes, often from different materials, to build a frame that is light yet strong. The Raleigh brochures of the day boasted that bonding gives stronger tube joins, compared to welding or brazing.
I really love the very visible engineering on these frames in the form of lugs, and the absence of messy welds (although the rear triangle is still welded). Let’s have a look at a couple of the bikes.
