PowerTap announces new P1 pedal and C1 chainring power meters

The Pedal Idea will definitely not work for Mtb'ing, those Keo type cleats will break so fast.

Well it looks like Stages for me...I'm fussy about what pedals I use and I ride a compact 50/34 which I don't think the new PT crank unit caters for.  

Do Stages have a Patent on their crank arm unit, just wondering why PT don't do something like that?

Bulk of the market means Shimano, means 4-bolt 110 BCD.

 

Powertap also needs to look at the TT market, because powertap hubs don't work in discs[1].  That means they should also look at 54 and 56 tooth rings.

 

 

[1] disc wheel covers do work.

Would this do you?

The chainrings are user replaceable - unless you change them with a hammer and chisel they won't need recalibration. Lik you say they have developed this system with most bikes in mind I'm sure they would have done a market survey to see what is the most common crank used...and as I have been informed - they will be releasing the newer Shimano 4 bolt standard in the next while...

it is not chinrings but merely a spider of some sort if I liik correctly. much like an SRM power ring on a sram crank. all this does is rotate your rings so that the bolt now sits inbetween the spider arms.

Am I looking at this right?

I use 50/36 and prefer it as the jump is not as high as 50/34 Suppose you climb more where you stay than us here in SA

I bought my first compact cranks way back in +/- 2004 / 2005 and they were only available in the 50/34 then. I'm quite happy with them so I ordered the same for my Tri bike last year albeit now in 11 speed.

I like to spin up steep climbs and the 34 with a 11/25 or 11/23 is works well for me.

That is 100% correct, the spider will make up the bulk of the cost of the system, as far as we can tell the rings will be propriety but we will see once we get our grubby paws on some.

The cost of the C1 system will be similar to a Dura Ace Stages arm BUT it will offer L/R balance etc to with in 1.5% accuracy.

In terms of availability we are looking at around May to have some of these new systems landed in S.A and final pricing can only be confirmed then as this Rand of ours doesn't know if its coming or going.

That spider moves inboard quite a bit.  Is this BB86 / BB386 compatible?

In theory it should be compatible yes. The main goal/ idea behind it was to keep the rings in the same plane as they were - keeping the chain line correct, as well as not having protrusions behind the rings to foul the frame in some applications.

Stages do have patents on their system, just as their is a patent on this system, perhaps the biggest downfall of Stages (and a few other crank based systems) is that you HAVE to run Alu crank/s and we have found that some of our clients do not want to do so.

The design intention was to add a power meter that can be fitted to a large majority of bikes sold worldwide without too much disturbance to the rest of the components and still be accurate - i.e. if you have carbon cranks then you don't need to sacrifice them to have a power meter.

Hi Power Tap. Would you know whether the C1 is compatible with the Look Zed2 crank?

from what i can see is yes it should be compatible as the look web page makes mention that the crank is both 110 and 130 BCD the PowerTap rings will be 110 BCD.

Will the pedals give power left and right?

But the crank only one side?

The cranks and pedals will give left right balance. although the cranks will be a calculated amount - similar to Quark.

here is a new video from the PowerTap guys, more details RE local pricing will be available next week. 

Here is just a few of the articles that have been published about the new products

Any news on pricing and launch dates in SA for the new powertap devices?

What changes were made to the g3 hub over previous versions?

Any news on pricing and launch dates in SA for the new powertap devices?

Pricing on the P1 Pedals will be around R15-16000 and the C1 Chainring will be around R10000, hopefully (depending on the R/$ rates). The pedals will be available in S.A early June and the rings early July all going well.

What changes were made to the g3 hub over previous versions?

The road G3 hubs have had no changes done, they are not changing the 32 hole G3 MTB hub as of yet, but they have released a new "road disc" hub which uses straight pull spokes and comes in 28 and 24 spoke configurations that will suit the newer MTB carbon rims like Roval, Syncros etc. 

They have managed to shave off about 120-150 grams with this new disc hub.

Nice, thanks - definitely keen for the c1 chain ring !
