@ timc – The reason for the steel on the Rocket is that during the development it become pretty obvious that there was going to be hardly anything in it weight-wise between aluminium and steel for the level of durability I wanted. That and the seat tube was much stiffer than the aluminium equivalent, so I could tie the suspension on properly.
The only way you’d shave significant weight off the Rocket and keep the durability is using carbon. 7.5lb 150mm frames aren’t that uncommon regardless of material. SB-66, Covert, Butcher all in that ballpark.
Makes sense, thanks for reply, it was a genuine question btw, not having a ‘pop’ at steel bikes!
out of interest where are the demo’s?
