PowerTap has long been a big player in the power meter market, but the distinctive oversized hubs are a relative rarity on the cyclocross course. While there are plenty of ’crossers who train with PowerTaps, most of those who choose to race with power typically opt for one of the crank-based meters like SRMs or Quarqs.
Part of the knock on PowerTaps was their weight. Another factor is the added expense of needing a PowerTap hub in a training wheel and at least one – perhaps several – race wheel. The new G3 PowerTap hubs tackles that first drawback head on. According to Eric Wallace of Saris, PowerTap’s parent company, the new hub is the lightest power meter on the market, adding about 100g to a comparable high-performance rear hub.
