SRM is the gold standard. Patented in 1987, SRM revolutionized training for cyclists, introducing the objective metric of power. No more guessing. No more relying on speed, heart rate, and feel. Power quantifies your limits so you can push them. Every SRM is hand-made, one at a time. Their quality is legendary. Throw anything at it: rain, mud, sand, snow, solvents and it won’t blink. All SRMs undergo a 144 point calibration to ensure accuracy. How good? Within 1%, good enough for use in laboratory studies. All SRMs are ANT+ compatible so you can pair it with your favorite head unit, have a battery life of 3000 hours for uninterrupted use, and have a global 3 year warranty. Get on board with the industry leader, and leave the peleton behind.
