Stages SB200 Launch: A Lighter, Smarter Redesign After Giant Acquisition

Key points

• The Stages SB200 weighs 70 lbs, a 55 lb reduction from the previous SB20 model, and includes roller wheels for easier relocation.
• The bike supports the OpenBikeControl protocol, an emerging open standard for trainer control, alongside Bluetooth FTMS and Zwift Protocol.
• Stages, acquired by Giant in 2024 after bankruptcy, has resumed manufacturing parts for the older SB20 and restored customer support channels.
• The SB200 features a dual-stage belt drive with 5x the inertia of the previous model, though reviewers noted audible freehub noise when coasting.
• Initial power accuracy issues were resolved via a firmware and inertia value update provided by Stages, achieving within 1.5% accuracy against reference pedals.

Background

Stages faced financial difficulties in 2024 due to excess inventory from the post-pandemic cycling boom, leading to bankruptcy. Giant subsequently acquired the brand and its engineering team. This acquisition allowed Stages to resume operations and launch new products like the SB200, while also addressing past customer support gaps for the discontinued SB20 model.

Why it matters

The SB200 represents a significant shift in indoor cycling hardware toward lighter, more home-friendly designs with open connectivity standards. Its support for OpenBikeControl could challenge the dominance of proprietary protocols like Zwift Protocol, potentially increasing interoperability for users. Additionally, the successful revival of Stages under Giant demonstrates the resilience of major cycling brands in the post-pandemic market.

What to watch

Stages plans to introduce a three-toggle smoothing system for ERG mode workouts to address user feedback on power volatility. The company is also monitoring the adoption of OpenBikeControl by other major manufacturers like Wahoo and Elite. Users with older SB20 units are encouraged to contact Stages for support, as parts and service lines have been restored.
