Like everyone else, we use different materials for our various models. A selection of our tubesets can be seen below.
We use a selection of tubes for our
steel frames. Our own 'PYPE' is
a custom drawn 4130 CrMo double butted (DB) and heat treated (HT) tubeset. This builds into a
lightweight frame that is both supple and strong. Reynolds 631 or Columbus Zona would be comparable in strength, weight and elongation (flexibility). Our 'BLX' tubeset is also custom drawn 4130DB CrMo, but this time without the heat treatment. Both of these tubesets would fall into the category of Aerospace Grade tubing. 4130 CrMo would be our normal choice for the rear stays of our bikes.
We also build with Reynolds 631, 725 and 853 and periodically, we'll select tubes from the other specialist manufacturers like Columbus and Tange.
Our standard Ti frames use plain gauge (PG) 100% seamless cold drawn Certified Aerospace Grade Ti
3Al/2.5V tubing. Our
dropouts are cut from Ti 6Al/4V plate. It's not so much about what the frame is made from but more about how one uses the material.
By selecting from a number of different tube
gauges and diametres, we are able to balance strength, weight and
'feel' to give you a frame that captures that 'feel' that only Ti and Steel can offer.
Bottom line, whatever your material choice, you can be assured that the tubeset selected meets the design specification of the frame. |
