Thats exactly what I was going to suggest. I have heard of people stacking up pieces of wood to the height of the riser and just mocking it up to see if there is tension on the cables.sgemt said:Hmm, well, it would be nice to know what kind of sled you have. This riser looks a little odd. Typically you can rise 2" without any extensions on any sled, sometimes 3" works. The only way you'll know is to unbolt your bars, lift them up, and measure how far you can lift them without extensions. Easy enough.
