Wanted: Power Meter

colm_gti

In the market for a power meter. Will be pulling the trigger on a brand new one this day next week if nothing suitable pops up on the second hand market.

Ideally looking for a powertap built into a training wheelset (32-36 spokes, clincher rim), as it will only be used for training, and easier to swap a wheel between bikes than it would a crank....

Would consider a crank based power meter if the price was right though.

Must be low mileage and/or recently serviced, and up-to-date with regard to firmware etc.
If powertap, ideally shimano freehub, but would consider campag if price is right. Rim must have little wear, and not need to be trued.
If crank based, must be bb91 (hollowtech II) compatible, don't want the hassle of changing bottom bracket. This probably limits my options to a Rotor 3D or shimano (or FSA??) crankset.

Cash waiting for the right deal!

What size cranks do you need?

175 or 172.5

I have a wired dura ace 175 srm.

Its off getting a new battery in the head and crank unit.

Would you be interested in it?

Ideally wanted something I could hook up to my garmin, but if the price was right I'd certainly consider it

Was looking in the region of a grand for it.

I'll give you a small bit if advice DON'T buy a power tap they are a nightmare. I'd go for a power2max worth every penny. I've had a power tap, power2max and srm and would hands down buy another power2max great value. Excellent costumer service too.

Thanks for that, why do you consider powertap a nightmare?

Had been looking at power2max as well, they seem to be in the same price range as powertaps...

I have 3 powertap wheels and have never had an issue . I know lads who have had issues but never anything too serious , the big downside is that if the torque tube goes on them it's expensive to get them repaired . Saying that if I was getting another pm I would buy the stages power meter which should be available in Europe at the start of next year . Good reviews and a good price , also very easy to change between bikes .

Yeah that looked so promising, until I read that it only measured left leg power and doubled it....not a little inaccurate?

What has me drawn to the powertap is not only the ease of changing between bikes, but the fact that it measures overall power output, and doesn't discriminate between legs...

Yep very easy to change between bikes but if you want power data on every ride and want different wheels for racing and so on , it makes it expensive every time you buy a set of wheels . If you look at dc rainmakers follow up review on the stages pm he rides with 4 pms on the bike and I think 6 head units to get a much results as possible and there is very little difference between them .
My next pm will be a stages .

Not too worried about changing wheels, power meter will only be used as a training tool, rarely obsess over figures during races as the bunch dictates the amount of work that has to be done. Don't do many TTs, and was looking at picking up an aerojacket for the few of them I do take part in. It'll be swapped between two bikes, which is manageable with a crank based pm, but much easier with a powertap wheel...

Cool you're sorted then , as I said earlier I've had no issues with mine anyway over the last 3 years.

My brother repairs and services power meters here in Ireland so has a very good knowledge of all the different 1's and was just passing in the info he gives me. He gets a lot more power taps then anything else in for repair. If the torque tune goes in them it's expensive to change. If you not doing big mileage then a power tap will last but if your doing big miles it's going to need more servicing than a crank based unit.
There is some1 selling a power to max on here have a look.

Couldn't that simply be because powertaps are far more common?

Colm, QuigSnr told me that a lot of powertap issues were from water ingress into the old "carbon windowed" models, I think this has been rectified in the newer hubs.

I'd go power2max though. TTs aside, I don't think a power meter is necessary for racing, in which case you could afford to keep it on a training bike.

Also, Hollowtech 2, come on! You can swap cranks nearly as fast as swapping a wheel. Come back to me when you get a power torque crankset and see how lucky you are, mine are pretty much fused to the bike at this point

I bought Fran's old Powertap a few years back and I have to say, whatever probs you had with it Fran, you put them right before you sold it because I put about 10,000 miles on it and only had to change the batteries in all that time. I upgraded to the Slightly lighter SL+ - which was basically new - and that gave a few more troubles, specifically with the bearings - apparently the stock ones are awful. Got them replaced recently - after less than 2000km - and the wheel is great again (although I have it laced to a 24 spoke Stans Alpha 340 with a matching front wheel to make the wheelset around 1550g, light enough to race on -which is a little flexy, although fine for my 68kg).

Interested in the Power2Max's though. Would love a new toy and buying parts will make up for missing training all weekend - or at least thats how I will justify it to myself.

There was a problem with the bearings and the end caps and the free hubs use to wear out but they will go in any wheel.
There just more expensive to buy for powertap. As you said your only 68kg and I'm 66kg so that's a help when it come to not wearing out parts. The new agents for powertap in Ireland are suppose to be a nightmare to deal with I've heard.....

They probably are more common but that's because there hasn't being any competion in regards cheaper power meters. I'd say in a few year there will be a lot more power meters around to be seen.

lennymc

another powertap user here, no problems, about 8000 kms on it, used in all weather, races, training, etc. Built into an open pro wheel. Changed the batteries on it once. I have heard that they can give trouble, but luckily Ive been ok. If I had the money i think id go with a crank based, but only so I could use my race wheels and power meter (and im a tart who likes shiney things)

ballyharpat

I have an old carbon window powertap and have about 9000 miles on it, never had a problem, and I ride it in all weather-snow, mud, rain, I swap it between bikes and use in for CX as well, I race with it in non-important races 'cos it is heavy, but it's a training tool.

I have a wireless SRM Pro for sale. The add is somewhere on boards but search doesn't seem to be playing ball with me today. Basically these are the details:

****

Switching between BB standards on bikes has meant I'm selling my Wireless SRM Pro crankset.

The spider/electronics and Duraace (7800) rings have 2,500km on them (TT bike) - the arms have 30,000km on them. It was serviced by SRM last November and used on the TT bike since. Checked slope before I took it off the bike.

Also comes with a brand new Duraace Octalink BB.

This is it on my old TT bike: https://plus.google.com/photos/111642730436367015877/albums/5896064242831264129?authkey=CPzLgbawkYqoDw

€1,000 (down from €1,200)

I tried via the "threads started by" which didn't work for some reason - I then simply did a search of your posts in the Cycling Adverts sub-forum. Alas our search powers are no stronger than yours

Thanks Ryan, got sorted with a Rotor 3D power2max though.
