Uli Schoberer invented the first-ever power meter in the late 1980s, fundamentally changing how cyclists train and race. This conversation traces his journey from medical engineering student to founder of SRM, revealing how strain gauges on the crank spider became the gold standard for measuring cycling power, and why this invention mattered more than almost anyone realized at the time.
Key Takeaways
- The spider (connection point between crank and chainrings) is the optimal location for power measurement because it isolates torque transmission and provides space for robust electronics without moving parts or crash exposure
- You don't need perfection at launch—aim for 80-90% and iterate. Chasing 100% completion kills momentum and leads to endless feature creep that prevents shipping
- Power meters shifted cycling from speed-only feedback to measurable biomechanical load, enabling training optimization similar to running and swimming where pace/timing already existed
- Building a hardware startup requires solving three interconnected problems simultaneously: the sensor, the computing device to record/display data, and the software to analyze it
- Wireless transmission (Bluetooth) requires constant power and complicates zero-offset calibration compared to wired systems, creating ongoing engineering trade-offs between convenience and precision
- Distribution and service infrastructure matter more than most founders realize—margins on repairs are thin, forcing direct investment in customer-facing operations rather than relying on distributors
Expert Quotes
"Don't give up and don't try to make everything right away 100% perfect. Be happy for the start with 80, 90%, and then finish the product and then make later go the next step. If you want something 100% perfect you will never get finished."
"You need to measure your power to describe the load you put on your body. In cycling you need the power because the speed doesn't tell you anything."
"I think if I would have not done it, someone else would have done it. I'm not sure, but I think someone else would have made it."
