Excalibur Cams.

What is ‘offset centre pull’ ? When we designed the Excalibur bow, we did not want to place the nocking point in the centre of the bow. This would have forced the grip too far down the riser affecting balance and aiming. So when the grip is placed where we know it shoots best, the nocking point is above centre.

But normally, when a string is drawn from a nocking point fixed above centre, the nocking point rises. This affects tuning and encourages the arrow to flex vertically through the shot. It becomes harder to tune.

We have designed our twin cams to deliver a true horizontal nock travel, even though it is not being drawn from centre. So you get the benefit of a riser geometry with a grip placed nearer to centre, but with the string delivery of a bow with a dead centre pull nocking point position.

Another new feature is the adjustable draw length. There is approximately 1" - 1.75" adjustment (depending on cam size). We have purposely limited the amount of draw length adjustment per cam to make sure feel and performance is consistent through each setting. In effect, we have only a 'Long' and 'Medium' draw setting on each cam. There is no short draw setting. We found setting a cam in its short setting adversely affected performance. In stead, we have manufactured multiple cam sizes so no matter what you draw length you know you are getting a cam working at its best.

We have also bucked the trend regarding axles and bearings. 3/16" axles and bearings have been undersized for years. We now use 6mm axles and bearings which are stiffer and flex less when shot.
