Description

Stages Cannondale Hollowgram Si Power Meter

The Stages Cannondale Hollowgram Si Power Meter is a BB30 compatible upgrade for existing Cannondale 2014 Hollowgram Si model cranks. This power meter will also work with Hollowgram SISL2 model cranks. The power meter features +/- 1.5% accuracy and 200 hours of battery life. Stages power meters run off the popular CR2032 battery and feature tool free battery replacement. In addition, it is extremely lightweight – adding only 15 grams to the weight of the crank arm. The power meter is compatible with both ANT+ and Bluetooth SMART devices, which means you can use your favorite bicycle computer as well as a smartphone or tablet.

The new Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy and have an LED indicator light on the housing for improved ease of use.

    Purchased the Stages power meter for Cannondale as a replacement for another brand that just didn’t work out. Quick shipping. Easy installation. Easy calibration. Works well with my Wahoo Elmnt computer. And it works. Every time. Provides accurate (or as accurate as can be for single sided) measurements. It has made my limited training time more efficient. Customer service has been excellent as these guys went out of their way to make me happy. Would surely purchase from PowerMeterCity again.

    I ordered this power meter after having had problems with another, far more expensive brand. First of all I have to say that the ease of ordering and the speed of delivery from power meter city is just fantastic. It took me five minutes to install this on my Cannondale and then I was off out on a 174 kilometer ride. Through wet, cool and scorching hot conditions, this meter has given me good, accurate data. Battery life is really good too. I am a very happy customer.

    I got this power meter since it had good reviews and seemed like a good option for my Cannondale. Shipping was fast and installation was a breeze. The power meter works well for what I bought it for, which is pacing up climbs or any smooth efforts up to about 1500W at high cadence. I was very disappointed to discover that this power meter drops out almost every time I stand up to pedal at above 1200W, and sometimes when I’m sitting down at over 1500W. It stays dropped out (cadence = 0) until I sit back down at < 1400W, sometimes with more than a 10 second dead period.

    I'm working with Stages Tech support to try to resolve the issue. They have been very responsive so far, but the latest firmware update that was supposed to fix my issue by using a magnet to measure cadence instead of analyzing your pedal stroke internally did not solve my problem. Essentially, their algorithm analyzes the torque vs. crank position I'm putting down, and says I'm not pedaling in high-torque situations. Since the issue seems algorithmic in nature, I would give them a decent chance of fixing the issue, especially since they have external cadence measurement capabilities built in. If they are able to resolve the issue, I will update this review.

    I have issues in the following regions at continuous power output (not an exhaustive list; measured by slowly increasing power until it drops out)
    1. Over 450W at ~40 rpm to get up a steep climp
    2. Over 1200W at ~80 rpm standing to crank up a kicker
    3. Over 1500W at up to 130 rpm seated or standing

    If you're over 100kg and can crank out some watts, this may not be the power meter for you (I don't know if other options would be better). If you have a more typical cyclist build, I'm sure it will be totally fine.

      Hi Ken. Thanks for the review. I’m glad to hear you are enjoying the power meter. Regarding the drops, I can’t say we have seen that before – on any Stages power meter for that matter. However, if there is anything at all you need from us to get things figured out, please let us know!

    This power meter was my first tool for power-based training and was an easy choice given the compatibility with my Cannondale and the price point. It’s been great so far. Both Stages and Power Meter City have provided top notch, responsive support. Overall, I would definitely recommend it.
