In 1986, Ulrich Schoberer designed, manufactured and submitted his patent application for the first spider-based cycling power meter.
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!
In the spring of 1988, SRM created the first cycling computer with the ability to record data. This was was yet another milestone in the creation of the new training metric which would become known as "training with power".
Rider contact points, like the pedal, were initially looked at for prime PowerMeter placement. After extensive testing, SRM determined the pedal option would not give the same durable performance and accurate torque measurements as the crank spider.
In order to accurately measure power, SRM tested torque measurements in the crank arm, against the measurements in the spider. The crank spider is the first point where pedaling forces from the left and right leg meet, before that force is transmitted to the drive train.
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.
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!"
The 3rd generation of the SRM PowerMeter and the PowerControl II. Having the SRM integrated with the Shimano Dura-Ace Crank Arm, gave professional riders a chance at racing with a power meter, while being 'sponsor correct'.
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.
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.
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!
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.
Uli Schoberer's BMW motorbike hosting the gadgets needed to transmit power data LIVE from professional riders' bikes at the Tour of Germany.
ARD (German television) aired segments of LIVE SRM data during the entire Tour de France. A graphic showing Power, Cadence, Speed and Heart Rate would update in real time showing the efforts being required during the race.
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.
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.
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.
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.
The SRM PowerMeter Shimano 7900 was an update over the previous 7800 version. With improved battery life from 1400 to 1900 hours and increased accuracy from +/-2% error to <1.5%. This came from custom manufactured strain gauges, improved battery design and a more efficient internal circuit board.
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 marked SRM's 25th Anniversary.
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.
Truly a masterpiece in its own rite, the SRM PowerMeter Shimano DA9000 has 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 latest SRM is truly the greatest.
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.
Today the SRM Training System has become standard equipment for the world's leading professionals in cycling and triathlon such as Greg Lemond, Mario Cippolini, Paolo Bettini, Erik Zabel, Nicole Cooke, Kristin Armstrong, Amber Neben, Sabine Spitz, Mark Cavendish, Bert Grabsch, Normann Stadler and many others, for national teams, sport universities, coaches and all recreational athletes who take training seriously. For years now they have being using the SRM Training System as a reliable and indispensable training instrument in cycling, and now professional athletes from other sports, such as NHL hockey players, cross-country skiers and Formula One drivers have started using them as well.
The principle has stood the test of time for 20 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 now 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.
The components that are used to build the SRM Training System are chosen because they are the best ones to do the job, and this is where our reputation for high quality comes from; the kind of quality that people have come to expect from German engineering.
Each system is custom made: different crank types (for example Shimano, FSA, Cannondale, Specialized etc), crank length, chain ring size, color of decal or PowerControl.
In the meantime word of the high-quality results achieved with the SRM Training System has spread outside the cycling scene: today sailing teams crank on special constructions to determine how many watts they must fill the sails with to keep ahead in the next ocean race, athletes in wheelchairs measure their performance, there are handbikes and even solutions for trotting races. And this is surely just the beginning of the many new ideas emerging from the SRM stable!
