Grams have been shaved, accuracy increased, and stiffness taken to a new a level. Of course, we’re talking concerning the new Quarq Elsa GXP. Representing the form of Quarq to return, the Elsa is packed stuffed with the recent and greatest in SRAM crank technology, in addition to carrying a couple of features which can be nothing short of revolutionary to crank-based powermeters. For Quarq’s ‘next wave of powermeters,’ we see an entire redesign over the Cinqo, with an emphasis placed on three key issues — weight, accuracy, and ease of use. And starting with weight, the Elsa features SRAM’s Exogram Hollow Carbon crankarms found at the recent iteration of SRAM RED. You can also find SRAM’s RED Powerglide chainrings from one model back. But, as the name implies, the cranks feature a hollow construction. On the other hand, what is not inferred is that the hollow cross-section design extends all of the method to the brand new spider, creating SRAM’s stiffest and lightest crank ever. Actually, your entire system tips the scales around 735 grams. For some viewpoint, the latest RED crankset weighs around 585 grams, and the last Quarq RED Exogram powermeter weighed 830 grams. So, the Elsa is sitting in a slightly respectable position. The Elsa’s innovative design did not stop at the crankarms. For a rigid crankarm attachment, the Elsa uses a newly designed, CNC-machined aluminum spider. The entire data-collecting electronics, and the system’s battery, is housed within the spider. Quarq is calling this OmniCal, but you’ll be able to call it liberating. OmniCal enables the powermeter system to gather data independent of the chainrings. So, you’ll be able to swap out rings without affecting the accuracy of the system. And speaking of accuracy, the Elsa powermeter system operates at the powerful ANT+ wireless system with an expressed accuracy of +/- 1.5% — an improvement over the Cinqo Saturn’s +/- 2%. Much more impressive is a new feature that we have only been witness to on pedal-based powermeter systems, Power Balance.
