Power Tap Pro-Pro's and Con's

I'm thinking of purchasing a PTP (I know the SRM is better but I have Campy components) has anyone used one? If so how did it work for you? Any problem with system? Thanks for the input.

Why does it matter that you have Campy? SRM is gonna run fine on any road group...cash on the other hand...

ts just a crank. you can use FSA with campy or shimano...why would it matter?

Anyway, I've got the powertap standard, and I like it a lot. I need to do some testing with it to determine power at LT, but I've only had it about a week and a half. The software is fairly easy to use, but if you have a newer laptop, you might not have a serial port to plub the reader into. thats the only realy negative I can think of.

Theres a guy on my team with the pro, and he has been using it a bit longer than I have. The main difference is a wired cadence, and the ability to use it as a regualr computer when you dont have the wheel in. Otherwise, I'm not sure its worth the $$.

According to their website it's only listed for Shimano, must be the chainrings.


I think I'm going with the PTP, I'm going to sit down with my new coach and go over it with him. I like the SRM's ability to be used with different wheels (i.e. training vr racing wheelsets) and if you were to factor that into the equation the price isn't that far off.

Phatman have you or your friend had any issues regarding the the hubs and water?

I havent used them in the rain yet for a long period of time. I got caught while doing an interval workout, but I went home, so 30 minutes or so in a decent rain, and no probs. I've heard that you should open the hub up and let it dry if you get really rained on.

Is the bottom bracket. Shimano is the octlink and Campy is taper.

the SRM is the actual crank. they make square taper and octalink. and dura ace 10.

heres a website that I got when I googled "SRM crank campy". http://www.usauzziesales.com/srm_power_meters.htm the SRM will work on campy.

Looks like I'm going w/PTP because my sponsor is a CycleOps dealer and I'll get a great deal. However the PTP doesn't have a Campy hub so I'll have to get a Mavic Shimano/Campy cog set to make it work. The PT Sl is Campy compatible but more than I want to spend just to save some weight.

Is not just weight with the SL model. It uses sealed cartridge bearing and the unit is literally waterproof. Longer battery life as well. I got the SL over the pro since the price difference was only $200+.

It's water proof or it's suppose to be water proof. My SL took on some water during/after a rain ride this last weekend and is basically dead (the hub batteries discharge in a matter of minutes due to a short caused by moisture in the housing). The downside to the SL is the fact that you cannot open it up and let it dry out the way you can with the older model. It's looking like mine is going back to Graber for repairs after only 4 weeks and 1200 miles use.

there's a guy on my team using one of the original powertaps with a campy conversion cassette, and he's had no problems. however, the powertap moves the whole cassette over a mm or 2, so you'll need to adjust your indexing or it will be slow to shift into smaller cogs. this applies to all gear systems though.

I'm reading on some other forums that the SL is having some tech problems and that they are taking up to 2 months to repair. I'm getting a little freaked out about buying one of these things if it going to be problematic. Other than SRM what other "true" power meter options are there? Any info on the Ergomo?

2R...some folks are having no problems with their SL's, mostly those who got some of the very first ones shipped from what I can see. I am riding one as a tester for my LBS. It is a lot more finicky than the Pro, in that it seems to be more sensitive to interference and you have to get the sensor install just right in order to eliminate datat drops. The Pro's don't have any of these problems as far as I know. I rode one from the bike shop for a couple of months while they were waiting for the SL's to arrive. I never had any issues with it and don't know of anyone who does. It might not be for you, but I wouldn't worry about the Pro's just because the SL's aren't ready for primetime yet.

Thanks Rule it seems like the consensus is that the Pro is the more proven of the two.

The only reason I was thinking of the Pro was because it's Campy compatable (I allready have three Record cogsets). It seems like by the time I get an aftermarket cogset for the Pro the cost difference won't be that great. However I think just from a reliability standpoint I would go with PTP instead.

This is pretty big purchase and I want to get it right, the SRM seems to be the gold standard but I just can't justify spending 2500 bucks on it. From what I've been able to research the Ergomo has it's own set of issues so I guess there isn't a perfect solution.

just to add in my two cents, my powertap is ****ed. I'm not sure whats wrong with it, but I went for a ride today, and it crapped out about a half hour in, and would fall asleep. I would hit the buttons the "wake it up" and was greeted with dashes. I raced it this weekend in a light rain, but It was never exposed to a continual downpour. I opened it up, there was no moisture, so I'm not sure whats wrong. I think I might try a warranty with the shop that I got it from. I'm kinda pissed that its done after 3-4 weeks.

This seems to be a consistant thread running through the PT world. Now I know that people who have a problem with a product will be the most vocal but on several forums I've run accross this same thing. I have a HAC4 which is a great 'general' training tool and IMHO the Polar is really not much more usefull (and costs twice as much) so the other options seem to be PTP/SRM/Ergomo. The SRM is just too much money for a club racer like myself the Ergomo has it's own issues and the PT line seems to be a bit fragile. Are there anymore PM's out there to choose from? Any better options?

So I just purchased a used PTP for $450.00.
Open Pro wheel
two bike kits
New computer (warrentee replacement)
All software etc.

I plan on buying a 28 hole hub only and building up a set of race wheels. All in all I should still be under buying a brand new one with only one set of wheels.

That's a good price. Enjoy

To follow up on my SL complaint earlier in this thread -
Graber/PowerTap has followed up with me on my SL and it appears there have been enough failures that they're holding off on "fixing" the hubs and on new production until they have all the issues worked out.

To soften the blow, they've sent me a new PT-Pro loaner wheel to use until my SL is back up and running. Even with the disappointment of having my SL die, that is really good customer service IMO. Kudos to Graber for stepping up.

From the SRM web site
RM Amateur model, with cranks compatible to Campagnolo axles (102mm) mounted. The chainrings are Shimano compatible (130mm bolt diameter from 38 to 64teeth).

That seems to be the consensus about Graber. Even though there seems to be some issues with the reliability of their product they are great about standing behind it. The system I bought the guy called about a computer failure and they sent him a new on even before they recieved the old one. So I'm getting a 3 month old computer out of the deal.

I decided to go with a "real" power meter because I've hired a coach and I want to get the most out of his advice. It seems to me that with out hard, repeatable data I'd be getting only 80% of what I was paying him for. Allthough the SRM is the best product for this the price is just too high for a old club racer like me.

Now what wheel should I lace up for the race set? No CF, just too much to loose in a crash. I was going to purchase a set of Reynolds Alta's before I decided to get the PTP I may still go this route and just have the rear laced to a 28h PTP hub.
