++++ update ++++<\/div>\n
Here are a few more pictures from my measurements:<\/div>\n
<\/div>\n
Enclosed the pressure distribution on the left and right leg, roughly balanced for me: 49 to 51. The smoother the arch (a clear kink can be seen here), the better the rider can handle the round step and can therefore maintain the pressure evenly.<\/div>\n
<\/div>\n
<\/a><\/div>\n
<\/div>\n
And here again my saddle pressure distribution. For a triathlete, typically more in the front third of the saddle and in terms of pressure, just ok. But I'm also considering trying a different saddle.<\/div>\n
<\/div>\n
<\/a><\/div>\n
<\/div>\n
Last but not least, the pressure distribution on the pedals. For me, the pressure on the right is more from the outside in. Usually, as on the left, it comes from within. On the right side, my pedal plate on the shoe was shifted for a long time, I'm almost sure that this is also the reason for the different pressure distribution. So check whether the correct and, above all, compliant setting of your pedal cleats!<\/div>\n
<\/div>\n
<\/a><\/div>\n
<\/div>\n
++++ update end ++++<\/div>\n
<\/div>\n
<\/a><\/div>\n

Today I was with J\u00f6rg from Bike Imperium to analyze my sitting position. After measuring all parameters and angles with the help of sensors, measuring foot and saddle pressure, we concluded that I am already sitting quite aggressively on the bike. Unfortunately with the result that J\u00f6rg cannot bring me further down the front of the cockpit without experiencing significant performance losses from km 120. For short competitions a lower position may still be possible, at the latest over the 180km it gets critical and we don't even know whether I can still run afterwards. Nevertheless we made small corrections. The front of the trailer turned up and the pads made a little closer to make the shoulder front 2cm smaller.<\/p>\n

It was interesting that the pressure on the right pedal comes from outside and on the left from inside. This is probably due to the fact that I sit slightly shifted on the saddle. This assumption is supported by the fact that the pressure on the saddle for me tends to move to the right half of the saddle and the right knee goes a few millimeters further forward than the left. So far I haven't had any complaints with it, so we'll leave it at that for now. A possible solution would be to rotate the pedal plate slightly outwards or to turn the saddle nose imperceptibly to the right. At the second test in a couple of weeks we will try a new saddle and a different trailer. All in all, I'm super satisfied. J\u00f6rg took his time again for hours and meticulously went through everything from the mobility analysis to the final adjustment. My full recommendation !!<\/p>\n

Here is a short report about Stephan, which had much more to do.<\/p>\n

Starting position: 2011 Hirschbachtal individual time trial<\/b><\/p>\n

<\/a><\/div>\n

As a pure cyclist you can sit Stephan up much more aggressively, that is, your back becomes straighter and he sits more stretched out on the bike. The attitude of the essay goes to improve significantly. The hands are far too overstretched and the entire holding load is on the arms and shoulders.<\/p>\n

After setting:<\/b><\/p>\n

<\/a><\/div>\n

Much more stretched and forward-oriented seating position. The angle between forearm and upper arm is optimal and the shoulders are relieved. Overall, it is significantly lower and therefore more aerodynamic. The angles between the upper body and thigh are still easy to move.<\/p>\n

The most glaring difference in the saddle pressure analysis:<\/p>\n

<\/a><\/div>\n

Before that, there was extreme pressure on the perineum area (left). Already so strong that blood is squeezed out over a long period of time and performance accordingly plummets. Another saddle (right) and the dam is relieved and the pressure is noticeably reduced. The feeling in the saddle, which he previously felt uncomfortable, disappears completely and Stephan can concentrate on cycling alone! Apart from the fact that especially with us men the pressure distribution on the left is very unfavorable.<\/p>\n

was fun and learned a lot again!
