I'm not sure exactly what you're asking. 44 teeth is the size of the sprocket. It's not part of the cranks. It bolts onto the drive side crank arm. You'll need an American sized bottom bracket (either the Redline or another) that fits 19mm spindles. That picture looks like a one piece crank, so I doubt that it will fit the Device's 19mm spindle.
The only other size to worry about, is the crank arm length. You existing cranks are probably 175mm. You can always install the 180s, if you want longer cranks.
EDIT: Forgot to add, you'll also need an adapter,
for your sprocket. You'll want the one labeled as "popular."
