Hey Guys, Just want to provide some insight into the whole braking discussion. Below are graphs created by the owner of Linkage, a linkage program used by the vast majority of bike designs, providing accurate information. "Anti-rise" is worked out as a percentage and relates to how much the suspension will or will not compress under braking. The higher the percentage of Anti-Rise, the stiffer and less responsive your suspension will be under braking. Leading to the feeling of 'Brake Jack' and more rear wheel chatter under braking. You will notice the conventional single pivot design (Sesta) has around a 90% anti-rise, and the horst link and VPP linkages are in the 60% range. Generally in a good design one will notice a lower percentage in downhill bikes due to extreme terrain conditions, accompanied by a much more progressive leverage curve. For XC and Trail bikes these parameters will change accordingly. On the PYGA braking system the brake pads will move up and down on the rotor by aprox 2-3mm. It is much easier for the pad to move up and down on the rotor, than the rotational force of the pads against the rotor. Therefore the up and down movement is not noticable (while riding). A static test will not give an accurate representation of how it reacts while riding, and will simply flex the rotor to the left. This does not happen when the wheel is rotating. Besides this, it will almost never occur that the brake is locked by the time the suspension is fully compressed. (In four years of using this design, PYGA have never experienced any shortcomings from this design, nor comebacks. Only compliments) PYGA Stage - Single Pivot - Starts at 54%, ending on 72% Specialized Stumpjumper 2016 - Horst Link - starts at 62%, ends at 68% Sesta - Single Pivot - Starts at 94%, ends at 86% Below is an explanation from the Linkage programs designer, about his thoughts on the PYGA Stage. He has never seen the bike in flesh or hasn't ridden it, it is just how he has interpreted the data from the graphs.
