You probably stumbled upon here looking for a review of a sports gadget. If you’re trying to decide which unit to buy – check out my in-depth reviews section. Some reviews are over 60 pages long when printed out, with hundreds of photos! I aim to leave no stone unturned.
Read My Sports Gadget Recommendations.
Here’s my most recent GPS watch guide here, and cycling GPS computers here. Plus there are smart trainers here, all in these guides cover almost every category of sports gadgets out there. Looking for the equipment I use day-to-day? I also just put together my complete ‘Gear I Use’ equipment list, from swim to bike to run and everything in between (plus a few extra things). And to compliment that, here’s The Girl’s (my wife’s) list. Enjoy, and thanks for stopping by!
Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!
The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2023 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.
“In general, the heavier the flywheel, the more realistic the inertia feel is.”
I always cringe a little bit at this statement – the inertia *is* related to the mass of the flywheel, but also to its radius (to the square of the radius to be more exact), and the shape of the flywheel. So – same mass, same shape, double the radius = quadruple the inertia; same mass, same radius, going from a full disk of uniform thickness to a flywheel concentrating the mass on the periphery = almost double the inertia.
Depending on the design, it does not take a lot for a heavier flywheel to have a lower inertia than a smaller one. You can compensate a 10% difference in weight by a 5% difference in radius to get the same inertia.
That’s all nice and well, but if you go into all-out nitpick mode and completely skip the transmission ratio between cassette and flywheel that might differ wildly between designs, the critique seems a bit… I don’t know, allow me to keep those words to myself ;)
Yeah, ultimately, there’s no great way to compare many things on smart trainers. Which is why I rarely discuss flywheel weight, and instead, focus more on how it actually feels.
But, to what I said in the article:
“In general, the heavier the flywheel, the more realistic the inertia feel is. Though, there are some exceptions to this rule.”
I think the second sentence covers this. :)
Noticed there hasn’t been any real new updates in the power meter world in a while. 2inpower released in 2017 I think, same goes for power2max NG, favero assioma
P2M NG has been updated recently with minor strain gauge refinement and a switch to a magnetic charging port instead of the micro usb. Falls in line with what Ray is saying about power meters undergoing minor tweaks instead of wholesale redesigns.
A bunch of useless things. Slightly updated, slightly optimised. WOW! One more brand released trainer! Only one missing. (or two) Garmin 540 and 840.
Ray,
How do you change the battery on the right side Stages Power Meter? Do you have to take the chainrings off?
The right is on the outside cradled next to the spider and arm. You do not need to remove the chainrings.
Thanks. I missed the picture showing the right side power meter “capsule” cradled in the outside next to the spider & arm.
“On the team of very minor updates, …”
Probably should be “theme” rather than “team”?
Hi DC!
nothing related to power meter for Time pedals?
thanks!
No updates from Rotor for their INSpider?
I found Shane’s review pretty damning and don’t consider it an option at the moment (INPower not an option for me as I need a shortened axle for a velomobile).
