I was at one of the presentations Leomo (and Hansen) gave at the Tour Down Under. The motion sensors aren’t new tech. They had them here last year. Their Type-S head unit (which is really just an Android phone) appears to make the process of recording / using the sensor data easier.
Take outs:
- It’s super nerdy. Which is ace.
- Hansen went from 180mm cranks to 177.5mm and had his fit/numbers/motion dialled within 35mins. This was impressive to see the process of measuring hip tilt/rock, leg extension/motion, etc.
- This system can quantify ‘smoothness’… and maybe trainer feel. That’s what caught my interest.
- What do the numbers really mean? We don’t know. It’s part of the puzzle, but not the whole picture. I assume for the complete picture we’d need to combine motion with optimal muscle engagement.
- The sensors can be used to set a baseline of your ‘optimal torso position’ on the bike (once you know it). You can then use those numbers to show you’re holding that position in racing/training.
I picked up a set of the sensors. I’m familiar with the Type-S head unit. I’ll see if I can replicate what Hansen did for his bike fit and go from there.
Other random thoughts when looking at this: The Wahoo TickrX and the Specialized ANGi both have x/y/z accelerometers that could be used to set a torso/head baseline and have that data on a head unit when riding. Another data point for Tri/TT riders. It’d be basic… but cheaper… or free for those who already have those sensors.
