Quiring Cycles

One of the great features of the recent move of Quiring Cycles, LLC into a larger building is that there is more room for production equipment and that these machines can all be housed under one roof.  Such was not the case in the past. 

The power operated Di-Acro Model 6 tubing bender (http://www.diacro.com/) was a machine owned by the business for many years, but it did not see much action until it was brought to the new shop from out of storage.  The result is that I can now play around with custom bending tubing to improve the functionality of a frame.

On 29'ers it is especially useful for riders with shorter inseams to have a frame custom built with more standover clearance with the top tube.   A way to do this is to bend the top tube in a downward arc.   

Above are two titanium frames I made in late 2011 for people who wanted (or needed) more standover clearance. The first was a 29'er with pearl true-blue panels.   The second bike was also a 29'er with the addition of a Lefty fork using an integrated Lefty headtube and a Ventana FS rear swing-arm set at 80 mm of travel.  This Ti FS 29'er frame was built for a rider who was 5 foot , 4.4 inches tall.

In theory, I could also bend seattubes for shorter chainstay lengths on 29'er single speeds and 1 x 10 setups.   Shorter chainstays usually means better climbing traction and a quicker bike for singletrack.  I will experiment with this idea as time progresses.
