FSA Powerbox power meter review

FSA has branched out from accessories like handlebars and stems into full groupsets; it's now dipped its toe into the power meter market with the new FSA Powerbox power meter

Cycling Weekly Verdict

The Powerbox is not really one for weight weenies, and there are power meter options that weigh a lot less and are cheaper but I would have no qualms in recommending this to get through the worse a winter can throw at it and still come out the other side in full working order, something that was the initial aim for the product.

Italian component manufacturer FSA has combined its wealth of experience with that of respected wireless electronic and power measuring experts Power2Max – a German company – to create the FSA Powerbox power meter. Power2Max has been producing power meters since 2010.

The FSA Powerbox power meter is supplied to the likes of Astana, Cofidis and Direct Energie as well as other pro teams. However, this partnership has allowed FSA to price one aluminium four-armed chainset (tested here) at the lower end of the price market, with a hollow carbon-cranked version available but at nearly double the price aimed at the higher end.
