EB14: New Quarq Elsa RS Power Meters for Shimano 4-Arm Hollowglide Chainrings

Quarq Dura-Ace DA9000 power meter crankset

Quarq has added another option to their crank spider based power meter offerings. Already stocking units for a variety of SRAM cranksets (including the new XX1 mountain bike version) Specialized and Cannondale, now you can add Dura-Ace DA9000 to the mix.

The unit gets all the new technology introduced with the XX1 model, including the multipoint temperature calibration to keep it accurate from 0º to 130º F (-17C to 54C) and accelerometer based cadence measurements. Those combine with their usual features – OmniCal (maintains accuracy regardless of chainring selection) and Power Balance (captures left and right side strokes independently).

You will have to swap to their ExoGram hollow carbon crank arm, but if you’ve already got the Shimano crankset, then at least you won’t have to buy new chainrings. Yes, SRM has offered 11-speed DA power meter cranks since last fall with a version of Shimano’s crank to maintain the aesthetic, but they’re double the price…

EB14: Garmin Vector Power Meter Pedals Go Single Sided, Not Quite Half the Cost

Garmin Vector S single sided pedal based bicycle power meter

With disruptors like Stages and upstarts like Watteam bringing power meter prices to more attainable levels, the bigger companies are reacting. Quarq dropped the chainrings to bring their crankset units in a little cheaper, and now Garmin’s simply cut the number of sensors in half.

The Vector S, which presumably stands for “single-sided”, drops the drive side power meter sensor and transmitter, leaving the left hand pedal to do all the work. The firmware is tweaked so the single pedal doubles the power output reading, then sends that number to your ANT+ compatible cycling computer. You lose the distinct left/right leg power measurements, but you save about $600.

It’s sold as a set, including the drive side pedal, Available for pre-order now for $899. That’s compared to the $1,499 for the dual sided system. An upgrade option will let you add the right hand power meter pedal in the future, too. Another pic and more details below…

EB14: Quarq XX1 MTB Power Meter Gets Official, Teases New Features for All Models

2015 Quarq XX1 crankset power meter

Quarq has officially launched their XX1 power meter spider for all SRAM 1x mountain bike cranksets. It’s available as a chassis, built onto an XX1 level crank arm using a new mounting interface and other new features.

It adds in “multipoint, active temperature compensation” that’s pulling from 10,000 data points to calibrate it as it’s cycled from 0° to 130° F. That provides a baseline setting for temps within that range. So, outta the box it knows what the calibration should be for any temperature you’re likely to ride in, staying accurate for the whole ride, season to season.

Power through for more new features that’ll carry over to all their power meters…

PSBCG90_vertical copy

As if there weren’t enough options for cycle computers already, now Pyle Audio’s Pyle Sports division is getting into the cycling game with their new PSBCG90 Smart Bicycling Computer. Since the 1960′s Pyle has been a name in the audio world with products like their Pyle Driver woofers, but since the 2000′s the company has been expanding their reach to include the sports and outdoor markets as well.

Admittedly a far cry from metal detectors, cooler bags with built-in sound systems, and hunting cameras, their first attempt at a cycling computer brings some interesting features to the table. Pyle PSBCG90 Smart Bicycling Computer in addition to a super long name offers post workout GPS functions, 80 hours of memory for functions like Ghost riders, and ANT+ compatibility, all under $140.

POC Octal AVIP Goes MIPS, 2015 Brings Additional Safety to the Road

Poc octal mips 2015

Just a few weeks ago, Scott Bikes unveiled what was called the first MIPS equipped road helmet in the ARX Plus Road. While it may have been the first we knew it wouldn’t be the last. During the launch of the POC Octal AVIP (Attention, Visibility, Interaction and Protection) helmet, one of the common questions was why not MIPS? We were told that a MIPS version might be in the works, and almost exactly a year later, here it is.

The Octal MIPS AVIP is just a sneak peek of an impressive new range of products which hopefully we’ll get to see in person at the upcoming Eurobike. For now, get the details on the new, safer, Octal after the jump…

Physiology and Nutrition: Strategies for Acute Recovery (Part 1)

crashRight next door to my office a new niche recovery lounge has opened up (RechargeSportSF.com) attending to the most under-emphasized aspect of training: Recovery. There are several types of recovery: the acute phase (the minutes to hours after training or racing), the day to day/week to week recovery, and, as we saw in the TdF, the recovery from traumatic crashes and broken bodies offered up by the precariousness of the peloton. In this article, I will focus on the acute recovery from a crash or surgery and exercise-induced muscle damage. (Part 2 will explore different modalities and optimal timing).

One of the biggest risks of our sport is crashing; the injuries ensuing -from broken collarbones to muscle crush injuries- are coupled with a long, arduous recovery process. It is well known (and most of us have experienced, at some point in our cycling careers) that the first week or two post injury is the hardest, with regard to regaining range of motion/movement and regaining muscle strength-firing patterns.

Injuries and consequent surgery are associated with hormonal and inflammatory stress responses that trigger a rapid muscle loss. In the first two weeks of disuse from injury, 150-400g of muscle mass can be lost from a single immobilized limb; coupled with metabolic changes that reduce the body’s ability to build muscle. Of additional concern is the functional strength loss from disuse; in general, this strength decline is approximately three times the rate of muscle mass loss. This functional strength loss is attributed to alterations in motor unit recruitment and the loss of skeletal calcium and magnesium stores (necessary for muscle contractions).

New Watteam PowerBeat Charges Up Left-Right Power Measurement on Any Crankset for $499

watteam powerbeat affordable bicycle power meter for any crankset

Nothing gives power to the people like a power meter that’ll fit any crankset and costs a fraction of competing units. That’s just what Watteam has done, surging to market with their new PowerBeat power meters.

Using a processing unit with built in transmitter wired to a strain gauge, the PowerBeat measures the effort put into each pedal stroke on each side. That means true, independent left and right side measurement. Each side weighs just 24.2g, yet it’s packed with features like dual ANT+ and Bluetooth Smart (LE) data transmission and a combination of strain gauges, gyros and accelerometers. It’s all housed in a weatherproof construction with user replaceable batteries.

The best part? It’ll mount to any crank arm -carbon, alloy, old, new, whatever- and it costs as little as $499…
