The new G2 or Second Generation Stages Systems have a much improved 'Pod' with the electronics isolated from the battery compartment to protect against moisture interference and with a much improved battery compartment closure. In addition, this new generation also see price drops of up to £100 per unit, making one of the most affordable power systems, even more so.

The offer of a complete chainset eliminates the extraneous Left Hand Crank if you were to buy just the left arm to upgrade your existing cranks. Obviously this won't apply to those already in possession of a crankset, but if you are building or upgrading then this is an elegant solution.

The patented Stages Power meter is primed to bring power-based training to all disciplines of performance cycling. With advanced technology and simple elegant design, the Stages Power meter is perfect for any cyclist whether looking for their first power meter or a savvy power-training expert wanting to add power measurement to a second bike. Regardless of what piqued your interest in power measurement, you’ll find the Stages Power meter to be the lightest, smallest, most technologically advanced unit available today.

Stages Power meters weigh just 20g (plus the crank arm weight) making it the lightest power meter available. In addition Stages Power meters unlike most systems, are 'bilingual' in terms of their communication and use both ANT+ and Bluetooth Smart protocols; the latter gives the ability to ‘future proof’ this power meter with the ability to update its firmware over the air using an iPhone 4S or iPad 3 (or later) devices, while also keeping its housing impenetrably sealed to the elements.

Measuring power at the left arm requires one assumption — that your left and right legs have a balanced power output. Stages have found with thousands of miles of testing, that power differential between legs has no significant influence on ride data and its value as a training tool. This assumption is the tenant to their ability to keep the complexity and cost of the system lower, all the while providing power measurement with ±2% accuracy (of the left leg's measured power).

The assumption of symmetry also gives major advantages over spider based torque measurements, which are forced to add complex algorithms or geometries in order to filter out unwanted torque measurements coming from chain line and crank position.

Ultimately the simplicity of the Stages design means that the Power meter is not only lighter and cheaper but also highly accurate and yields repeatable results with only a very slim margin of error.

Available in 2 ring configurations Compact (50/34) and MID / PRO Compact (52/36)and in 3 lengths : 170, 172.5 and 175mm

Stages Cycling is located in Boulder, Colorado, a Front Range city with a long pedigree of producing and serving as the proving ground for many of America’s elite cyclists and triathletes.

The area provides 300-plus days of sunshine for those athletes to test themselves on the iconic roads surrounding the city, many of which are steeped in history - the Morgul Bismark and its infamous wall - or soon to be historic - Flagstaff Mountain, which served as a mountain finish to stage 6 of the 2012 USA Pro Cycling Challenge.

Stages Cycling is deeply rooted in Boulder’s work hard, play hard philosophy. We here at Stages Cycling pedal the talk, and more often than not spend our lunch hours pounding out miles on these historic roads and climbs. On the weekend, you’re just as likely to find us racing on the road, track, trails, or the bike parks in town or in the mountains west of the city.
