Hoyt Pro series HPX, right-hand riser. I am advised that this is a 27inch riser. It measures 19inches between limb bolts and has a total length of 26.5inches. 

There are a few dinks normal for a used riser, plus a little wear around the limb pockets. I bought it secondhand from my former club along with a set of formula 38lb F4 carbon limbs (also for sale) but nothing else. I never used them and now no longer shoot.

Postage cost will be £15
