Purchase Power Meter Advice


Recommended Posts

Hi Guys,

I would like to start training with Power.  I would like advice of what power meter to use.  Ideally it would be relatively easy to transfer from TT bike to Road bike between seasons.  Also I don't want to spend a fortune as I'm not that good - just a mop type person who wants to train and race with power.

Thoughts on make/model that you would recommend.

Thanks

Favero Assioma Uno pedals. Single sided power. I got them for $595 from 99bikes, they price matched and applied 5% member discount (membership is free). You may close the thread admin.

Will you be swapping it between seasons or sessions as the regularity of changing may play a part in your decision.

Is your crank length and chainring size the same on both bikes?

I have a stages on my roadie that works fine. I change it quite often between road bikes and is not that much of a faff but it reads way higher than anything else (not an issue really as it is consistently high)- cheap and possibly rightfully so

I have a SRM on TT bike that reads more like what I would expect and even though is a crank would be able to change if required. - very pricey but got it off facebook

Based on reviews here, i am looking to get favero pedals next on TT as I want to go shorter crank length and dont want to drop money on another SRM.. @willie can hook you up?

99bikes in Joondalup. Price matched down to $625 (or whatever it was) then the 5% applied.

Assume they matched the bikebug price as they seem the cheapest?  I asked my local 99 bikes and they'd match the non discounted prices that bikebug has.. wish these franchises would have consistent policies

I bought the Favero Assioma dual sided pedals from Willie. Make sure to put some grease on the thread each time you move them between bikes. I can swap them over in about 5 minutes.

I bought a set of Look Keo pedals, which use the same cleats. That way I do not have to swap the pedals over for a one off ride.

Yeah use and rate the assioma from Favero. I have one huge gripe, they read about 100 watts to low 100% of the time. I swear it's not me :P

There's about 10 people off here that have bought them from me and touch wood, haven't had any back yet. 1 pair out of about 25 came back. More than half Vectors did come back so I stopped selling them. Only Bored@ is too cool for Assiomas. 

I'll see what I can do. But I'm a little fish so can't afford to lose on them like 99 bikes. 

Anyone else want some while I'm at it? 

Yep they are ugly looking pedals. Don't go the SRM pedals they are shit. 

I just changed over to Quarq on my Roadie (only power meter that fits the 12 speed cranks) & Power2Max on the TT rig. 

I'm very happy with both & doubt I'll go back to pedal based in the future.

Totally forget about the Power2max thought they must have gone down the gurgler.. looks like not  bad option for crank based and old reviews were always pretty good..

Did you get just the powermeter or get cranks etc as well

I'm currently using a 4iiii Ultegra Left Only crank and it has been great. Got it online for under $500 delivered. You would be able to swap between bikes presuming that your crank lengths are the same on both bikes (same model would be preferred for aesthetics ;). Advantages here is that you get to keep your current pedals and cleats.

Have also owned the PowerTap P1S pedals as well. They were nice and easy to sway over. Good battery life. Paired easily and were very reliable. Obviously you would need to swap cleats over if you don't have the Look Keo type.

I have a Stages and swap between road and TT bike. Both Ultegra but different ages so doesn't look same, but crank length is same and that is the main thing.

Doing it slowing and thoroughly is about 15 min, loosen 4 screws; 2 on each bike, flick up lock, pull off, put on silicon grease, push on other bike, push down lock, tighten 2 screws and done (also don't generally put the spare crank on the other bike).

Easy and power consistent between bikes

What? Didn't you race Kona in 2016?! Or was that another Mungo?!!

No, you are right Cranky. Mungo is a machine. He is also the pilot for John Demandle who together held the World Record for para Ironman not so long ago.

Sorry Mungo 😘

What do you do for additional cleats (if you have a couple of pairs of shoes)? Do you know if normal Look Keo cleats do the job.

Cheers

does anyone race these days without a power meter?  I am worried as i don't have any way to measure watts outdoors.

What's a power meter???

(Or perhaps I should have said watts a power meter...)
I'm with Surfer and have absolutely no intention to buy one.

I don't race anymore, but if I did I wouldn't use it to race. I might use it "in a race", but purely to see watt whats :) I race at afterwards.

I use it more for training than racing. Which I suppose is obvious considering I'm hardly racing these days. But it means that when you're training you get the most bang for your buck and you can't slacken off because your numbers tell you if you are doing so. 

Speed is not always a good indicator in a race situation, especially if there are hills or wind. I found this when I did Ironman Cairns. I had people racing pass me on the bike but I just stuck to my numbers and then I passed them on the run because they had smoked themselves on the bike, either trying to keep up with the others or trying to keep their speed constant, I am assuming.

You don't need one but I love mine. Except for when I do my FTP tests and it keeps telling me to reduce my numbers. 😞

excellent. you have all convinced me to save my money. I will race by feel mainly, with an eye on heart rate, but also an eye on avg speed. 

Personally I find Power meters to be of most benefit in a TT because of difference in (my) perceived effort Vs actual effort - especially in the first half - and that my best TTs come from a consistent actual effort, not perceived effort.  Having said that, after using power for a while you get to know yourself better and you can probably go back to "adjusted perceived effort" and you'll be pretty right.  The problem with avg speed is adjusting for hills and headwinds. A watt is a watt no matter what the conditions, the powermeter doesn't lie. :)

Bump to ask... how is this going? Still ok?

Am thinking of getting either the single or double sided ones.

I got the doubles about a month ago. Going great so far. Super easy to install and swap between bikes

only problem is I had to swap the cleats on my shoes. Was using shimano spd-sl. On my tri shoes I couldn’t get the old cleats off so have to get some new ones

Yups pretty happy with the Faveros. Had zero issues. They are highly regarded and I’ve not heard of Anyone complaining.

Hmm, Ive been spending a lot this year, but a bit over the less than generous strava estimate for off road power.

I know that there's the SRM spd off road pedals but I'm yet to see a review of them. 

 

I'm saving for the Stages GRX LH Crank arm

Have you validated with another PM or is this like my bathroom scales continually overestimating my weight? :)

It is severely under doing my weight or the slope. There is no way I climb at 90 watts for 26 km

Indeed. I am guilty of being a slave to numbers in the past with various wired and wireless SRM's (all bought second hand) on 6 bikes including on my CX bike.

But not now? ✌️

 

I just find the data and what it tells me interesting. Not using it for performance.

Lost motivation to ride and hadn't raced since mid 2015. The later was the big driver to monitor my numbers as I did tailor my training to it. Only just now finally back on the bike to manage Covid kg's within my 5km circle after not even riding 18 months! 

Last of my PCV head units battery finally died 3 weeks ago and I only just sent 2 head units off to SRM Oceania in SA for battery replacements last Friday! To be honest I've just been enjoying riding looking at the scenery rather than staring at the head unit so didn't mind the blank screen... Though was still downloading the feeble data after my Covid km's when it was working out of habit.

Contemplating getting out onto the Velodrome again this summer to race with my club. If this happens (the racing and me racing) I'll take the numbers seriously again.
