In 1986, Ulrich Schoberer designed, manufactured and submitted his patent application for the first spider-based cycling power meter. 1986: OUR BEGINNING In 1987, a patent was awarded for the first Power Meter for "Crank Drive Application" on a bicycle. Thus, a new era in performance training for cycling was born! 1987: PATENT AWARDED TO ULRICH SCHOBERER In the spring of 1988, SRM created the first cycling computer with the ability to record data. This was yet another milestone in the creation of the new training metric, which would become known as "training with power". 1988: THE FIRST SRM TRAINING SYSTEM Different drivetrain points, like the pedals, cranks or spindle were initially looked at for prime PowerMeter placement. After extensive testing, SRM determined these options would not give the same durable performance and accurate torque measurements as the crank spider. 1988: EARLY POWERMETER PROTOTYPES In 1991, the German National team hosted a training camp in St. Moritz, Switzerland, which featured SRM PowerMeters. This gave professional riders their first chance at training with the latest technology. 1991: PRO-RIDERS TAKE NOTICE Greg Lemond was one of the first professional riders to see the value in training with power. He has gone on to say, "If I had trained with an SRM sooner, I would have won more races!" 1991: EARLY ADOPTER The 4th generation of the SRM PowerMeter and the PowerControl IV, saw improvements in accuracy and in data recording to allow for 1 second recording intervals and enough computer memory for up to 10 hours of data. 1993: CONSTANTLY IMPROVING DESIGN In 1997 Bjarne Riis won the Amstel Gold Race with an SRM Training System. Having trained with the SRM on the Amstel course months prior, he was able to tailor his training to meet the specific demands for the race. 1997: RACE DATA SHOWS ITS VALUE 1999 marked a milestone in SRM's history. For the first 12 years, SRM manufacturing and sales were run from the home of Ulrich Schoberer. Now seeing SRM as a thriving business, he decided to expand! 1999: SRM HQ The 5th generation of the SRM PowerMeter gave increased battery life, up to 1500 hours of use. Also the additional options for square taper and Octalink bottom brackets were offered. 1999: THE NEXT STEP Uli Schoberer's BMW motorbike hosting the gadgets needed to transmit power data LIVE from professional riders' bikes at the Tour of Germany. 2000: TELEMTRY MAKES ITS DEBUT Jens Voigt raced the Tour de France in 2004 while testing the first version prototype of the new SRM PowerMeter retrofitted with Shimano Dura-Ace FC-7800 cranks. The overwhelming response from customers quickly made it the best selling PowerMeter in SRM's product line up. 2004: The beginning of a product era Beginning in 2005, SRM began working with Cannondale Bicycles to offer SRM specific model PowerMeters with the SI (System Integrated) Cranksets. This was the first time SRM's were sold as an OEM product, being sold with Cannondale's Team Saeco edition bike. 2005: SRM goes mass market! Initially started in 2006, Project "Wireless" was intended to bring PowerMeters into the next era by cutting the cords! SRM's internal development engineers worked with Dynastream to perfect the Power Protocol used for the ANT+ wireless code. Launched in 2008, SRM's became fully wireless and ANT+ compatible. 2006: The wireless age In late 2009, SRM began producing and assembling PowerMeter's in Colorado Springs, CO. With the increase in popularity, production in Colorado was focused primarily on mountain bike model SRM PowerMeters. All electronic components are still produced in Germany. 2009: Bringing production to the USA In 2011, SRM innovation continued beyond cycling with the BMW/Oracle Sailing Team. Working with SRM, a performance measurement system was designed to monitor the "grinders" during training and competition. The grinders have the most physically demanding job aboard a yacht, having to pull rope by a hand activated winch. 2011: Innovation beyond cycling 2011 marked SRM's 25th Anniversary. 2011: 25 years strong Campagnolo began working with SRM in 2008 to design a PowerMeter for their Record level groupo. After 5 years of design and testing, the SRM PowerMeter Campagnolo was released and became the "must-have" PowerMeter for Campagnolo enthusiasts. 2012: Campagnolo joins forces with SRM Truly a masterpiece in its own rite, the SRM PowerMeter Shimano DA9000 had over a decade of pedigree behind it. Having been refined and redesigned with multiple revisions and input from countless hours of racing in the professional peloton, the SRM was truly the greatest for a lot of years. 2013: The most sold PowerMeter to date! The SRM PowerControl 8 was another milestone for SRM. With the support for .FIT files, Bluetooth, Wifi, GPS, magnetic USB connectivity and an awesome screen, it showed the industry the way forward. 2014: Launch of the SRM PC8 2016 was the year the first versions of the SRM Origin PowerMeter went to market. Since then, the Origin PowerMeter has adapted to new standards and trends, thanks to its unique modular system. 2016: Launch of the SRM Origin 2018 SRM enters into a long term collaboration with LOOK. The Exakt PowerMeter is SRMs first Pedal based PowerMeter. With its outstanding reliability and accuracy it brings measuring opportunities to cyclists without compromising the reliability of the data! 2018: Launch of the SRM & LOOK EXAKT With the launch of the SRM X-Power Pedals, we have been the first to bring pedal based PowerMeters to the MTB and Gravel. With market leading integration and accuracy, the X-Power have been a big step forward for pedal PowerMeters. 2019: Launch of the SRM X-POWER 2021 we launched the 9th generation of our spider PowerMeter. With the new PowerMeter, we took the design we had perfected over the years and added many modern features. It was now able to work without a cadence magnet and support for Bluetooth, and several cycling metrics, was added. 2021: SRM PowerMeter 9 The original Power Meter 1986 The original Power Meter 1986 SRM Bike Power Meter Patent SRM Bike Power Meter Patent The first SRM Training System Early Power Meter Pedal Prototypes Early Pedal Power Meter, Spindle Power Meter and Crank Power Meter Prototypes The German National Team using SRM Power Meters in 1991 The German National Team using SRM Power Meters in 1991 Greg Lemond using the SRM Power Meter Greg Lemond using the SRM Power Meter SRM Powermeter 4 and PowerControl 4 SRM Powermeter 4 and PowerControl 4 Bjarne Riis using the SRM Powermeter and PowerControl SRM HQ building site in 1999 SRM HQ building site in 1999 SRM PowerMeter 5 SRM PowerMeter 5 Power Data Telemetry at the Tour of Germany Power Data Telemetry at the Tour of Germany SRM Dura Ace PowerMeter SRM Dura Ace PowerMeter The first Cannondale Power Meter The first Cannondale Power Meter SRM now working from Colorado SRM now working from Colorado SRM in the Americas cup SRM in the Americas cup The 25th Anniversary version of the PC7 The 25th Anniversary version of the PC7 SRM for Campagnolo SRM for Campagnolo SRM PowerMeter for Shimano Dura Ace 9000 SRM PowerControl 8 in Red SRM PC8 The SRM Origin PowerMeter with Dura Ace chainrings The first SRM Origin Modular Power Meter SRM and LOOK Exakt Pedals SRM and LOOK Exakt Pedals SRM X-Power SPD Power Meter Pedals SRM Origin Carbon Power Meter 9

SRM – Schoberer Rad Messtechnik – was founded by engineer Ulrich Schoberer in 1986. Prior to this the qualified medical engineer had spent many years thinking up and experimenting with ways to measure an athlete’s power output on the pedals under real conditions during an actual ride.

Up until the eighties, no adequate method had been found to measure performance on a bike in training or racing, you still had to rely on lab testing instead. This meant that athletes were forced to go back and forth between their real performance – cycling on the road or cross country – and the ergometer in the lab. With lab testing, they still couldn’t tell how their performance had changed over a period of a few hours, either in a race or in training. Lab testing was an intermittent check-up, at best, but couldn’t tell athletes anything about how they were performing day-to-day. And the most important performance – during competition – couldn’t be tested.

It wasn‘t until Ulrich Schoberer developed and patented the SRM Training System that it at last became possible to measure power in watts while cycling. SRMs measure the only aspect of training that is absolute, POWER, which isn’t affected by the kinds of influences, like weather conditions (temperature, wind) you see when you measure physiological variables such as heart rate or speed. Even better, pedalling power is measured at the point where output really occurs, on the special crank, the SRM Powermeter.

The development of the SRM systems began in 1986, and since then their further development has benefited from the ideas and experience of important sport scientists, coaches, trainers and professional cyclists from Italy, Great Britain, the USA and Germany.

Over the years, SRM Training Systems have become the reference tool for the best cyclists in the world. Athletes like Greg Lemond, Mario Cippolini, Erik Zabel, Andre Greipel, Peter Sagan, Mark Cavendish and Tadej Pogacar, national teams, sport universities, coaches and serious recreational athletes have been using SRM PowerMeters to get the best out of themselves. And so, have professional athletes from other sports, such as NHL hockey players, cross-country skiers and Formula One drivers.

The principle has stood the test of time for over 30 years, and under every condition imaginable; SRMs were even used on board the MIR space station under conditions of zero gravity.
To meet the ever-increasing demand from the field of professionals, serious amateurs, and hobby athletes – the SRM Training System is available in any number of different versions. Whether on the road, cross-country or on the track, our SRM engineers have developed efficient and specific solutions for every area.
