Adam Hansen's Paris-Nice Time Trial with the TYPE-R

I am happy to do my first of many blog posts on the LEOMO site. Now that I have used the TYPE-R quite regularly there is no better way to start off than with some race data! With the most recent one, Paris Nice, stage 5, the Time Trial.


The course of the TT was a nice lap around Barbentane, 25.5kms in total. Fairly flat at the start, with a few bridges and overpasses before a steady incline into a not so easy hill in the middle before a tailwind fast finish, then ending with a short steep climb. Yeah Ouch! I did both a recon of the race with the LEOMO TYPE-R and also raced with it.  Today I would like to look at both files and compare the data.


So for a basic overview:




In the left column you see the breakdown of the recon ride, on the right, is the race. Unfortunately, I don't have an SRM on my Race TT Bike as I have on my Training TT bike at home. However, it is very easy to spot some big differences in how the body reacts from riding easy to riding hard. Let us start from the top of the body and work our way down.


Take a look at the data produced from the pelvic sensor:




During the recon ride, I rode very easy, 8 mins slower than in the race. I can see that I am more relaxed and can hold my position better with just looking at the Pelvic Range Angle during the recon. As soon as I add some intensity in the race my pelvis wants to tilt upwards. This is because I lose form when I am pushing harder, there is more than 5-degree Pelvic range difference from 33.4-degrees in the recon to 38.5-degrees in the race. With my Pelvic Rotation, I scored an average of 10.5-degrees of movement compared to 10.7-degrees during the race. I have to admit, while I have done a lot of work with the LEOMO getting my road bike position better, I have not done anything yet making my TT position better with the TYPE-R and it shows, I don't like the idea of my hips  rotating so much, so this file is a good starting point. My Pelvic Rotation, in my opinion, is too high, this range should be far lower. On my road bike, I am about half this range. So after Milan San Remo, I know what I need to work on, my TT position. As with the Pelvic Rock, it is not rocket science that during the race it is worse than in the recon. When I apply force to the pedals my pelvic rocks backwards because I am having trouble maintaining good form, it jumps from 5.1-degrees to 7.2-degrees. I think I could assume that those extra 2.1-degrees difference is also a reason why my Pelvic Angle increased from the two rides as I saw above. When the force is not as great on the pedals, my pelvis can handle a more stable position with the easier load and I can maintain a better posture.



My Leg Angle Range is fairly good here. The numbers match up pretty well. There is very little difference from the recon to the race. If anything it could be a little too high. I only know this because of the experience I have from using the TYPE-R with my Road Bike. Because the LAR is a little high for me here it could also be a reason why my Pelvis Rotation is high also. It could mean that my seat is a bit high, so my legs have a greater range to travel, maybe too far, which could cause my pelvis to rotate so much as I showed before.



My Foot Angle Range in the recon is almost the same from the left leg to the right leg. I am just cruising here. If you look at the graph above the left and right leg yellow lines follow each other very well. Soon as you scan over the Race FAR, there is a difference. Like on my Road Bike my left leg is better. In other sports, my left leg is the dominant leg and also my strongest leg. These graphs above show in the FAR(Q1) that I handle the load better when applying greater force to the pedal, with less movement than my right foot when I first apply forces on the top of the pedal stroke. In the FAR it actually gets better in the race when I get serious from the two legs and the Dead Spot Score shows this. There is far too much movement in my right foot to maintain a good DSS for me. I am seeing nothing new. On my road bike, it is the same, not as bad, because I have worked on this, which you will read about in later blogs here. When I go harder in the race, both DSS improve as I am focusing more on my pedaling. But I still lose out a lot. This needs work on.


As I said, this is the first time I have seen race data and a recon ride together. It's interesting for me because I rode the exact same course, one time with a lot more effort and the two files show that my motion is different under load when everything else is the same, bike position and course profile. The numbers don't lie. I know I have not done much work with my TT position and these numbers show I should. From this, I think I can take away some good information. First up, my LAR is a tad high and this could be the cause of my Pelvic Rotation being twice as high on my TT bike as my road bike. Lowering my seat could stop this overextension and help maintain a more stable position in the Pelvis. Which could also help with my Pelvic Rock and hopefully improve my DSS without affecting performance. So, next time I have TT training I am going to try a lower seat height and see the difference in the data and I expect some improvements. Stay tuned!

    I am impressed with the capabilities of the TYPE-R. I would love to see the data from more pro riders.

    Very interesting post Adam. How long did it take you to learn everything? It seems a lot of numbers that I have never heard of before.
