Subject: Affordable Power Options
Educate me on some affordable options to start training with power, please.

Background: I've done around 5 HIM and one IM all based on HR and perceived exertion. I do a decent of riding on the trainer. I would hope to stay in the $1,000-$1,200 range but could be talked into $1,500 if the cost/benefit was there. My wheelset is the stock wheels that came with my felt b16 with a disc cover.

There seem like there are so many options to choose from, just want to understand the pros/cons. Thanks in advance!!

choices are mostly

- hub based, like the Powertap. Easy to use, accurate and reliable but not ideal if you have multiple wheels or plan to buy new wheels etc. I have a PT and really like it.

- crank based, like Quarq and Power2max. Easy to use, accurate, reliable but a little harder to move from bike to bike but takes less than a few minutes IF you have the same bottom bracket on different bikes. Reasonably priced. A stages is also crank based but single leg multiplied by 2. I personally would avoid. If you go the crank route consider if you want to move to compact/mid compact/shorter cranks at the same time. I have a Quarq and it's my goto PM.

- pedal based like Powertap pedals and Garmin Vectors. A bit more expensive. Some people claim the vectors are more finnicky. I have a pair and love them. Powertap pedals were really well received but I suspect you will now hear of growing pains. But I think they are very good devices. Very convenient to move from one bike to the other or travel.

$ wise the Power2max is probably a really good option right now.

Lots of other names out there like 4iiii but still have to prove themselves

If I were buying today it would be a set of P1 pedals. If you time it right you can get in around $900 (backcountry coupon). i currently use a G3 hub on my training wheel that I cover for races. I also really like my PM and easy to switch between road and Tri bike, which is why I am sticking with it

that would be Powertap P1 pedals or Garmin Vector pedals but I think you meant the first.

FYI, there have been some occurences of P1s reading a little high amongst some of the pros over on ST. Most people rarely complain when their PM reads high :-)

With power meters growing in popularity, the used market is quite good now.  Used PT wheels (wireless) can probably be had for around $400.  Used Quarqs probably in the $500-700 range...cheaper if it's the older Cinco versions.

I started off with a powertap wheel when I first got into cycling and tris.  Used it all the time between my road bike and tri bike, with a disc cover for triathlon races.  As I got more involved in road racing though, I wanted a different rear wheel option while still having power, so I moved to a Quarq.  The powertap was completely hassle free and rock solid.  The Quarq (older cinco version) is pretty solid, but sometimes moisture or temperature swings mess with on rare occasions.  I think the newer stuff is much better at it though.

For most people, I would advise a used PT wheel with a disc cover for racing.  Cheap, reliable, easy to swap between bikes without having to worry about compatibility.  If you find out you want something else later, you probably still get most of your money back if you choose to sell it.  If you buy it used for $400...a year later it's still probably worth at least $300...and wouldn't be surprised if you get the full $400 back.  Used market for pedals is similar as you don't worry about compatibility issues.  With crank based, you have to sift through a bit more as you have variations in BCD size (standard or compact), bottom brackets, and crank arm lengths.

Indeed, I waited and waited and got my hands on a Powerbeam pro used in mint condition for $300!

I had 4iiii, but sold it because it wouldn't fit on my new frame. After that I bought a stages because it was slimmer and would fit on both of my frames. Overall I didn't notice a difference between the two power meters when riding and assuming they both fit I would go with the cheaper one. I also got my stages when it was a closeout though so the price difference wasn't much at all. Because I switch between two bikes often I chose to do stages so I could swap out my crank arms quickly and move on. I'm happy with my purchase overall. I do have power dropouts though, but I just got a new battery so hopefully it will fix it. I had that issue on both pm's and it seems to be quite common. I got my power meter for around $400 and I believe it was worth it. In the end I chose have a power meter (400) and a tacx vortex smart for enjoying zwift (300) for less than most people spend on just one of the items. For what I use them for I am very happy. That being said if you have the money to spend there are other options that are technically better.

I will take some crap with my option. I have been an iBike user since training for 2007 IM Lake Placid. I have had several generations of their product, with legit results. I like the flexibility of using on both my road and tri bike. Currently I am using Garmin 920xt with their PowerPod. My numbers on Computrainer vs. PowerPod are right in line, as with the other iBike units I have owned. This gadget (PowerPod) is about $300 for their basic model, more with some of their wizardry (I have the PowerStroke option which "video's" pedaling stroke calculates wasted watts. Their software for analysis again serves the purpose as I realize I am never going to be a Pro and only want to continue to improve my cycling, I realize that there may be some variability in not using a DFPM, and for my budget and purposes PowerPod has been serving me very well.

I found a race wheel with a powertap hub, barely used, for 800 bucks, CANADIAN dollars, so even cheaper in USD.

Super happy with it, affordable, works.

Just bought a used Powertap wheel (DT Swiss something or other) for $280 shipped on eBay.  I'm going to swap out the rim and spokes to a Flo 30 at some point and then get a disc cover.

For $1200, you're well above the cost of a brand new Power2Max crank for example... (starting at $650, but you'll get a Rotor 3D for $750 for example). A brand new Quarq starts at $780 (DZero Aluminum) with the DZero Carbon starting at $1100.

Used, expect to pay about $500-700 for Quarq. A used PowerTap rear wheel will be somewhere between $350 and 1000 depending on what wheel it's laced to.

With that kind of budget, there are few options that aren't open to you.

Powertap offers 3 "easy button" answers for you: C1 chain rings, P1 (or P1/S) pedals, or a pre-built wheel with a GS or G3 hub. You can be all in for anywhere between $600-$1200. All 3 options have "ease of install/uninstall" going for them, so you can take them with you to your next bike with a minimum of hassle. The wheel, and, to a lesser degree, the pedals, are portable enough that you could maybe share them between two bikes should you expand your stable to include a road bike.

That said, and assuming you see yourself keeping the Felt for a while, I'd really look at a crank-based system. With chain rings and installation, a Quarq Dzero Carbon probably comes close to your absolute budget cap, but it's a "two-for" upgrade. Not only are you getting a top-tier power meter, you're significantly upgrading your crankset to something that's (presumably) stiffer, and significantly lighter (366 grams, or over 8/10th of a pound) than the FSA Omega set that's the o.e. spec on a B16.
