PSA: Used Vector 3 + Rally XC Conversion Kit is a great cheap SPD Power Meter

DCR made a video about this when the Garmin Rally power meter pedals launched, so I knew it was possible. But, I hadn’t actually ever done the math around whether it would be worth it if you didn’t already have a set of Vector 3s laying around. Yesterday a friend of mine mentioned that he did exactly that over the summer; back when the Rally XC 200 were in short supply and…

Garmin’s Rally XC SPD Power Meter Pedal Information Leaked

While SPD is clearly the best pedal system available, one drawback is that there aren’t many (read, only one) pedal based power meters available for the platform. It looks like that is changing though, with Garmin bringing out some new “Rally” pedals. Which alongside the SPD, there are also SPD-SL and Keo options (not that it matters ;)). This is all thanks to a post on Trainer Road’s forum, which has since…

Advocating for Dual-Sided Power Meters

Single-sided power meters are far and away the most popular kind of power meter. There are a few reasons for that, but the biggest are that it’s cheaper and easier to do it that way. Buy a new crank arm with a power pod, and swap it for the left arm on your bike. Done. For an experienced mechanic, this should only take about five minutes. While that is cheap[er] and easy,…

Specialized S-Works Power Cranks Broken

It’s never great when something breaks, but when that thing is an expensive power meter, it really sucks… In this case, it’s the right side power meter – which while everything looks good in the Specialized Power Cranks app, just isn’t reporting any power. My “solution” so far has to been to remove the battery from the right crank, and just run one-sided, so at least the left-side doubles the power and…

Left side only!!! WTF

I mentioned that I had some concerns around iQ² making a big deal about shipping a one set of pedals to DC Rainmaker, but it turns out that it’s much worse than I thought. They actually only shipped a single sided power meter. Yeah, two years in, and they can only do single-sided power. SMH… Anyway, as he does, Ray digs into the pros, cons, and other in this first-look.…

I want whatever SRM is smoking

Not really, it wouldn’t be good for my asthma. But, whatever they are hitting, it must be choice, because $1199 for dual-sided power might have been a reasonable price back when they started working on these pedals, but with everyone slashing prices the last few months. It’s not any more. Some of course would argue that SRM is “first to market” with the X-Power, and that is true if we narrowly define…

iQ² – Vapor no more

By my recollection, it’s about 18 months late, but iQ² has actually delivered a mass-produced power meter pedal. To one person, and wait-for-it, a second one later this week! IKR! Exciting news! Kidding aside, this is actually good tepid news. On one hand it’s great that they have the confidence to send a “final” sample out to reviewers, but on the other, if this really is final hardware, why isn’t everyone who…

Case study: An incomplete power meter review

Testing a power meter isn’t hard, as long as you have the appropriate control. It doesn’t matter how cost competitive the meter is. Accuracy matters. Capture the data, do the analysis, and show it all. So we can double check your work. It’s simply not good enough, to call it at this: From our tests the Avio ran a few watts higher compared to power meters we know to be accurate, but…

IQ² MTB Should, maybe, come in June/July 2020

Not quite two years ago, IQ² got enough people to back the [incredibly innovative, but alas, not sound from an engineering perspective] power meter dongle (?) designed to sit agnosticlly between the pedal and the crank. As a SPD rider, yes, even on the road, this seemed the perfect place to measure power; without the drawbacks of putting the power meter in a consumable pedal. Oh, and the price was perfect. Unfortunately,…
