And a $350 gut, re-build and upgrade of a unit that is out of warranty is not bad consumer support I feel


Monza quoted me $650 to replace the internals of my PT a couple of weeks ago. Needless to say I decided against it.

Who does it for $350?

Curious what your fixes were for bearing and battery life issues?

Bearings were replaced with some Japanese ones, much better.

As for battery, the 'cheap and easy' fix (assuming you have the updated firmware) was more in contrast to what is costs to get a SRM battery replaced. PT is obviously just a quick unscrew of the cap and replacing with batteries that are not all that expensive.

Well that escalted quickly....

Anyhow, As I am not a pro, or don't intend on competing at any high level, I have gone for the Power2Max

Rotor 3D with 130BCD 53/39 O-Rings.
Went 3D over 3D+ so that I can swap between bikes when/if I need to...

Meter, crank, rings, bolts, tool.... £950ish delivered.

Thanks guys.


Just to correct, 3D+ is NOT BB30. It can be used on BB30, that's right. But the spindle has the length of a 24mm Shimano crank, so it can be used on BSA or BB86 frames. You would just need the right bearings.

It has a 30mm spindle rather than 24mm is what I meant.

Yeah it can be used in BB86 with adapters but I'd rather the ease if interchangeability between one bike and another that has ultegra cranks.

Mario, how did you establish the power 'over reading' that the P2M was giving? Not that I don't believe you, just curious on your process.

That would be a little concerning if I were an owner.

As a Campag user, it really would be nice for there to be a discrete alternative to a chunky Powertap or phenomenally expensive Record SRM.

As for Powertap, I've been generally happy over the past few years. Bearing are rough and need replacing quite often and the torque tube does need adjusting if you do decent mileage. But the product gives reliable data, more than could be said for some of the alternatives that I tried.

My SRM is a delight - sadly pricing puts it out of the ballpark for many (including me) unless picked up used. Very few used Campag cranks.....

On campy you could always run the cannondale SRM with praxis or cannondale rings. Otherwise yeah, its expensive campy SRM time.

10sp SRM cranks are fine on 11sp Campag.

Used SRAM and Shimano without an issue.

I'm not following, so excuse me if it's just my morning's coffee not yet kicking in, but:

I run Campy. I've got a Rotor 3D crank installed with Quarq and Q-rings. Runs flawlessly. Based on this, I don't see anything wrong with running Rotor's PM with Q-rings for my next build, which is nice as that one I can get in compact and run either 52-36 or 53-38 Q-rings on it. Can of course go with a selection of round rings if Q isn't your thing. Based on that, I wouldn't anticipate any issues running Power2Max with Campy either, as you could put it on Rotor 3D or 3D+, or a number of other options. Granted, you aren't running a Campy crank, but it works perfectly fine.

I ran a Rotor Quarq for a while. Horrible problems in the mountains - unreliable data. It didn't last. It also looks like something out of a cheap Disney scifi film of the eighties (to my eyes sorry).

Can't run my SRM Hollowgram either as I now have a standard BB.

The Csmpagnolo SRM is a thing of beauty. It is expensive, but worth it.

Really? Mine's been solid. And what's wrong with cheap Disney-style 80's sci-fi? It was awesome! :mrgreen: No worries though. I'm not really seeing it, although it may be because mine's on Rotor TT Q rings and a 3D crank. The Quarq unit just blends in on my setup, but ymmv for sure.

Try the Rotor PM. Cleaner lines, good weight and reads power on both sides. At least, it's another alternative, as is the Power2Max, if you don;t like Quarq. I'll be able to report on the Rotor PM and my experiences with it in the mountains in the fall (I hope), as well as having power comparison data between it and the Quarq.

For me the problem with a non-Campagnolo SRM is the Q-factor. I looked through all of them on the SRM site and found only cranks that are wider than Campagnolo.
