We Tested a $3,000 Telemetry System: Is It Worth It?

Jennifer Miller · 2026-10-02

Professional data acquisition has been a staple in World Cup racing for years, helping riders shave hundredths of a second off their runs. But can amateur riders benefit from a system that costs $3,000? We spent months testing the BYB Tech Telemetry V3 Pro on trails to find out. If you want to compete at the sharp end of today's Downhill, Enduro, or Cross Country World Cup, instinct alone won't cut it anymore. Delicate cables and small data boxes are now common on race bikes, recording every movement of fork and shock with millisecond precision. Among the leaders in this field is BYB Tech, based in Italy. Founded by former Elite Masters downhill champion and automation engineer Enrico Rodella, the small team grew from a Kickstarter campaign in 2018 into one of the top telemetry suppliers on the World Cup circuit. Today, the company has three full-time employees and one part-time team member, delivering data insights once available only to professional teams. So why bother? Isn't a good feel for the bike and the classic rubber O-ring on the fork stanchion enough? BYB Tech claims their V3 Pro system turns subjective impressions into reliable data, making suspension setup understandable and repeatable. But does this flood of data justify the hefty price tag? And more importantly, can you make sense of the analysis without an aerospace engineering degree? ### What's Included and What Can It Measure? For $3,000 (excluding VAT), you get a system with an IP65 rating, making it resistant to dust and water spray. At its core is the central data acquisition unit, which processes data at up to 1,000 Hz—that's 1,000 measurements per second. The box includes: - V3 Pro data acquisition unit: stores all measurement data and features a three-axis accelerometer and gyroscope - Two linear potentiometers: measure suspension travel on the fork and shock - Brake sensors: detect when brakes are applied - External GPS receiver: records your route and speed - Magnetic wheel sensor: measures wheel speed with high precision directly at the wheel - Comprehensive mounting hardware If you want to dive deeper, the unit can pair via ANT+ or Bluetooth with external sensors like heart rate monitors and power meters. Action cameras can also be synchronized, allowing you to overlay telemetry data onto your video. This is powerful for analyzing why a load spike occurred—whether it was a riding mistake, poor line choice, or an untidy landing. ### Installation: Zip Ties, Double-Sided Tape, and a Little Patience Installing the BYB Tech system for the first time requires careful attention and mechanical confidence. If you know what you're doing, it takes about 15 to 20 minutes. For first-timers, it can take considerably longer. Frame designs with the shock deep inside the down tube or routed through the seat tube require creative mounting for the shock sensor. On our test bikes—a Trek Fuel+ EX and a YT DECOY SN—installation was straightforward. For selected models, BYB offers free downloadable 3D printing files for dedicated mounting brackets. For most bikes, the supplied universal mounts are all you need. Everything secures with cable ties and double-sided adhesive tape. ### The Verdict: Is It Worth It for Amateurs? After months of testing, we found the BYB Tech Telemetry V3 Pro to be a powerful tool—if you're willing to invest the time and money. For serious amateurs chasing podiums, the data can uncover inefficiencies you'd never feel otherwise. But for casual riders, the cost and complexity might outweigh the benefits. As one tester put it, "It's like having a coach in your pocket, but you need to speak its language." If you're ready to geek out on suspension setup and have the budget, the V3 Pro delivers. Just be prepared to learn.
