In racing, the yoke serves three purposes. The first is to stop the saddle from slipping back too far, secondly to provide the rider with a grab strap when necessary and finally to provide an anchor point for a running attachment. As the owner of Nunn Finer and as an active competitor, I dont always like throwing on a full breastplate but enjoy the easy adjustment and added security of a yoke like this one. I figured if I liked it so much, there must be others out there who are looking for one, so we are adding it to our offering. It comes with Zinc hardware fittings.
