Ok, I'll start. I have a P2M with a 110BCD spider adapter for a Rotor 3D+ crank. If I wanted to move my current P2M over to my MTB, with a 110/74 BCD double CR and a Rotor 3D crank, would that pose a problem at all or would it be a straight swap over since both are 110 outer CR bolt patterns? I might be interested in the new P2M when it becomes available and I want to start planning moving things about.

Regards,
Dave

Hi Dave,

unfortunately that doesn't work for two reasons: firstly the MTB sensor is completely different (4 bolts vs 5 bolts, adapter for inner chain ring, and different chain line). Also the sensor differs between the 3D and 3D+ - the cranks have different interfaces.

Cheers
Nicolas

Hi have a Cannondale Slice which has BB30 and a Gossamer Crank (110mm) if I buy the p2m with the FSA crank that's on sale I would have to buy the adaptor as well (Rotor BB30 to BB24 which is also on your site?). With this I could use my existing chainrings as well? Last question does the PMeter have a temp sensor?

Thanks,
Rob

Nicolas,

Is there an appropriate Power2max combination to give one 155mm cranks that would easily go on a Trek Speed Concept?

Thanks,

Hugh

Not Nicolas, but the Rotor 3D and 3D+ are the only P2M-compatible cranks that you can get with a 155mm crank length. And the 3D+ is BB30, so you're left with the 3D as the only option assuming you can find a bottom bracket that will work with whatever is on the SC (BB90?).

Thanks........That had been my impression but wanted to double check. The SC is a BB90 so one obviously needs the appropriate bearings to mate the 3D to that frame.

Ditto. I haven't had any issues with the product since I first installed it. Very happy.

Which power2max power meter would I get for my bone stock Cervelo P5-three bike? It has a 54/36 Rotor 3D+ front crank and if you need anymore information on that, well, I'm totally dumb on those type things. I just get on it an pedal. : )

Christmas is coming and this is what Santa is bringing me, whether (s)he knows it or not.

Thanks!

Toby

@ Rob: that's right, the bb30to24 is the right bottom bracket. You'll be able to use your existing chain rings without problems. And yes our power meters have active temperature compensation.

@Hugh:the 3D is indeed the crank of choice, but unfortunately the shortest we have is 165mm.

Hi Toby ,

54/36 sounds odd , could out be 52/36? In this case all you need is the sensor for 3D+ cranks and the installation tool and you're good to go.

You just get the standard Trek bearings for a Shimano crankset, the 3D is interchangeable with Shimano. The interface between the P2Max and 3D is the same as the stock 3D (unlike SRM), so you can source a 155mm 3D crankset separately and fit it to a P2Max spider. I had to do that to get a 165mm P2Max at a time when P2Max didn't offer 165mm.

I've obviously slept since I've looked at my bike. Crap...you're right (and let the flaming begin)...it's a 52/36.

Thanks!

If one bought a 155mm Rotor3D crank separately, could the P2M sensor be used on it? Or is there some modification to the crankarms or some interference that would prevent the shorter arms from being used?

hi,

got my P2M[/url] yesterday and am using it with the navi2coach[/url].

my question now is regarding the calibration before each ride. is it necessary to do a manual zero before the ride? I guess not as it should zero when not pedaling for 3 sec right? But in the navi2coach[/url] setting for the powermeter[/url] it says that auto-zero is not supported.

thanks,
Jakob[/url]

My question too is about the auto calibration.
Does the auto calibration feature actually change the calibration value or does it just change the internal processing algorithm?
For instance, if I start a ride and my calibration is at 1249 and then during the ride that experiences a huge temperature swing, and provided I stop pedalling a few times for the autocalibrate to kick in, will the calibration factor I see on my head unit after the ride change from 1249?
thanks

Just ordered the P2Max for my new P3 and I'm waiting anxiously for it to arrive. I have Rotor 3df cranks so I just ordered the power meter itself. Anybody know how hard it is to install? I actually asked a few of the LBS around here and nobody had even heard of it.

VERY easy. to attach the sensor to the crank (instead of the spider) they will send you the rotor tool and then you only need a 32mm wrench to tighten it. put the rings on and inseart the batterie and that's it.

@PHXATC: great, 52/36 is 110bcd (compact), so you would need to choose that version. What chain rings do you use?

@asad137: you could use 3D crank arms purchased separately. No modification needed. Just use the specific tool you can get from us to install the power meter on it.

@Jakob1989: that's right, you don't need to auto zero because the power2max will auto zero every time you stop pedalling for 2 seconds or more. What the navi2coach menu refers to is turning auto zero on and off. On our units it is always turned on to make sure you get the most consistent data.

@Russ Brand: the calibration value reported on your unit is just for your reference. The power2max calculates power and then transmits that, so auto zero changes the calculation, as you say. You can actually forget about the number you see on the screen because you have two mechanisms keeping your data true: auto zero every time you stop pedaling and temperature compensation for temperature changes in between. The latter one would only matter if you did a huge long climb where the temperature dropped significantly during a very long period of sustained pedaling. In practice auto zero has you covered in 99% of the case. For the last 1% we have included the temperature compensation.

@parasky: we have a video showing the installation procedure. Sorry it's still in German, have to get around to dubbing it in English.

Cheers to all,
Nicolas

Absolutely. Other than getting the spider off (which evidently was a bear when my LBS did it - money well spent) I now have a bike that I hop on and power numbers magically come out. In fact, if I wouldn't have found this PM I wouldn't have bought my S5.

I'm subscribing because I just installed the gossamer power2max. I read that it's not compatible with aero chainrings but I was able to install the alloy Trimax aero chainring without a problem at least with clearance. Is there a problem with the power number it will put out?

Hi Nicholas,
I just picked up a Cannondale Slice Hi-Mod with the Cannondale SL crank 130bcd. I was told I would have to wait until February2014 for the new version if I didn't want to have to buy new crank arms. Is this correct? I am curious what makes it incompatible.
Thanks.
