Straitline Vertical Wedge System Stem (NEW in box)

I have a brand spanking new 70mm Ti grey Straitline stem for sale (in box never been mounted).
Steer tube clamp size: 1-1/8"
Bar clamp size: 25.4mm

Awesome piece of gear but I ordered the wrong size bar clamp. Here is item description from Chain Reaction Cycles:

Straitline's new vertical wedge clamp stems use a unique clamping method to attach to the steer tube for disgusting amounts of clamping force. Designed for the ever growing long travel forks and those who test their limits. The patent applied design can provide many times the clamping force of traditional split clamp designs, shaving weight and setting another standard.

There is plenty of room for design improvements in this industry, and Straitline will bring it to you without any hype.

Features:
• 25.4 - 70 mm 276 grams, 10 degree rise
• Lightweight radical appearance with new clamping standards
• Simplistic design provides an unparallel clamping force
• Will not crush a steer tube at max clamping force
• Vertical wedge clamp maintains constant equal contact, 360 degrees around the steer tube
• Motocross inspired method of bar clamping starting with the top two then torquing the bottom
