Which power meter – Stages or Power2Max?
Powercal doesn’t use calibration for subject. They tried but found it added no additional accuracy.
Was just reading that over at dcrainmaker. Wonder how it would work out power then as my HR at a specific power would be very different to someone else’s HR at the same power. Am puzzled. Shall give it a go though and see how it does.Posted 3 years agoTiRedMember
I thought that too. So i tested it on a 1st cat racer in a club chaingang with his srm. It was still accurate for summary measures. It is not a power meter, but is better than it has any right to be. I have one on circulation in the club – out with a tt’ist this week, and just ordered another after my HR strap died.
Running two head units to compare was a bigger expense!Posted 3 years ago
Thanks TiRed, sounds like witchcraft to me! I’ll run it alongside the powertap and see how it does.
Still no closer to deciding on a proper PM though. The Stages was edging it by being easily swappable between bikes (though complicated by running different crank lengths on different bikes – and you can swap the P2M between cranks) but I’ve now heard some mixed reviews from club members on theirs.Posted 3 years ago
Anyone tried the Vector pedals? My LBS tells me they have some demo ones, along with a Quaq, so may give them a try. The price is a bit off putting but the ease of switching between bikes makes them tempting. Though looks like even the Garmin team don’t seem to like them much.Posted 3 years ago
New review of the iBike Newton over at road.cc. I quite like the idea, but 780 quid?! Ok, you don’t need an additional cycle computer, but most people have one already and the one you get is a bit rubbish. Shame they couldn’t just do a small box with the sensors in it that clamps to the bars and talks to a garmin/iphone, and charge about 250 quid for it.Posted 3 years ago
I’m still undecided between P2M and Stages, but have just noticed powermeter24.de have 15% off the Stages FSA and SRAM versions (ie less than 600€ + shipping). I have to replace a borked crank anyway – an FSA sl-k + Stages would be odd (carbon DS, ali NDS!) but would make for a pretty light solution.
Also spotted this (as yet unreleased) idea which measures power at the cleat http://www.brimbrothers.com/Posted 3 years ago
Had to change battery today on my stages ultegra for first time absolutely no way u get 200 hours as stages state I counted my hours from garmin connect uploads bought in May done about 56 hours so slightly disappointing. This is offset though by the fact that I had a spare battery which took at best 20 secs to change over and cost virtually nish.Posted 3 years ago
Looks like Rotor have a new lower cost version (E990) of their PM. Single sided now on the NDS like the Stages, but you do get a full crankset for the price. I’d still probably go P2M.Posted 3 years ago
That’s pretty dire. Considering I’ve yet to change the battery in my HRM strap after about 3 years’ use! I’ve read of a battery bug in the FW, maybe isn’t going to sleep.
I’ve gone for the Stages in the end. It’ll do what I want it to, and it’s the cheapest option for me, even after having to buy a compatible crank (a cheapish s/h FSA K Force) – should come in a lot lighter than the P2M too.
Of course, I’ve just noticed Mrblobby’s graphic on the previous page 😐 so fingers crossed it’s going to fit! (Crank hasn’t arrived yet to measure up)Posted 3 years ago
I took advantage of Powermeter24’s Stages discount to pick up the SRAM X9 version for about £470 vs £600 in the UK.
I have been umming and ahhing about this for a while but with seeing the German price and being able to get a brand new X9 driveside crank arm for silly money from a guy on ebay not 10 miles down the road I took it as a sign of divine intervention 😀
Just waiting on a direct mount chainring and some matte black crankskins to cover up the branding and it will be good to go 😀
PS: For any weightweenies wondering… the stock SRAM X9 cranks arms are 553g so with the direct mount ring it should be just 14g heavier than my Rotor 3D with Extralite Octaone and alu bolts (or 34g heavier with the Stages sensor). Not too shabby and the X9 arms look alright in the fleshPosted 3 years agotpbikerMember
I bought a stages…
Didn’t even work! I mailed stages and they asked me ‘when you calibrate it is the number shown 0?’ When I answered yes they just told me to take it back as the strain gauges were clearly borked.
Not sure if this is another common issue or not. Customer service was spot on, but a bit shoddy that I waited for a month for delivey and it arrived broken!Posted 3 years ago
Rotor LT available to pre-order at sigmasport for £799 (better price than I expected!) Same UK price as the DA Stages, and you get both crank arms, pretty good I reckon. Though is BB30 so may need a new BB to accommodate. If I was going to buy a stages I think I’d now be seriously considering this.
Edit… reading the dcrainmaker comment on it…
While their existing full ROTOR Power system is priced very high at $2,350, at least it was in the ballpark of other similar system (albeit the high end of that ballpark). In the case of the LT though, it’s basically double the price of the Stages Power Meter ($699). And also in the case of the ROTOR LT, there’s nothing it really offers beyond what Stages can do. In fact, one could (easily) argue it does less. For example, ROTOR doesn’t dual-transmit ANT+ and Bluetooth Smart like Stages does. Nor does it include Stages new high-speed data mode (targeted at track athletes). Nor can you install it on 3rd party cranks like Stages can be.
I suspect his view may change somewhat if he were to consider the UK/EU price of the Stages!Posted 3 years ago
Does anyone with Stages have some advice to get the best out of it? For example there seem to be improvements in battery life with the auto-off and so on… Should a firmware update before the first use be all that is needed to make sure everything is running as smoothly as possible? Any other tricks or tips to consider?Posted 3 years ago
DanW, any problems you’re trying to sort out, or just general musings? Firmware upgrade if there is one available sounds like a good idea regardless. Does sound like they rushed it to market a bit and are slowly sorting out issues in the firmware. Nice that you can do it all over the Bluetooth via an app.
Should be getting the power2max this week, which will hopefully just work!Posted 3 years agothisisnotaspoonMember
What’s the reason Stages can’t sell a chainset in this country, is it the distributor network (i.e. they can’t because madison have the rights to shimano, fisher SRAM and windwave FSA?).
Could mean that the Rotor crank doesn’t suffer the same price inflation as the Stages.
I wonder if Shimano have anything like stages up their sleave to compete with Quark/SRAM. Heck they could install them OEM on DA cranks, still be cheaper than a lot of the competition and probably kill off a lot of the PM market.Posted 3 years ago
Shimano have filed patents so they are definitely thinking about it. Sounds similar to the Rotor one with the strain gauges embedded in the crank arms. Can’t imagine it being significantly cheaper than anything else out there though. I do wonder if pricing of new models is just aligned with competition, or whether these things are really that expensive to make and sell?
You might be right about Stages, I just assumed they chose not to. Also assumed price inflation was more to do with being an US product imported into the UK.Posted 3 years ago
Odd (or maybe somehow makes sense commercially) that Rotor flog OE cranks to P2M, and are now undercutting them with their own power meter.
My Stages came on Saturday, “just worked” after updating the FW with the android app. I did think it was a dud, as after installing it I could pair it to the garmin but when spinning the cranks on the workstand neither cadence nor power registered. Worked fine on a test run though.Posted 3 years ago
The battery cover o ring had a healthy smear of grease on it, let’s see how we get on…
