What is 612 Select?

You may have noticed that many of our models now come with a little tubing decal on the seattube that reads "612 Select."  You may also be asking yourself, what the heck is that?  Well my friends here is your long overdue explanation.

We spend a crazy amount of time designing our frames, dialing in not just the geometries but the tubing diameters, wall thicknesses and butting profiles to get the feel of the bike just right. We do this not just on one frame size, but across them all, making sure that each size of every model is precisely tuned to give the rider the experience and thrill that they’ve come to expect from a bike wearing the Hennepin Bridge headtube badge.

It’s a process and result that we’re quite proud of, so we decided to give our proprietary blend of double-butted 4130 Cro-Moly tubes a name. That name is 612 Select.

so, it’s a double butted 4130 cro-mo tube set with a MN area code?
Looks butted on the three main tubes, with straight gauge, shaped, rear triangle?

Awful lot of verbage to not say anything. Are your writers ex-politicians? Or politicians in training? Some of us look for more than smarmy marketing rhetoric.

Er, am I right in thinking this is in fact A612 steel, and not 4130?
