Power meters.......

That's a brilliant deal. I'm about to pull the trigger on a Quarq Dzero, just trying to work out which crank length would work best.

Same length as existing cranks....

This is going on my TT bike which just got spare cranks I had lying around (172.5mm). There appears to be a benefit to position from shorter cranks but I'm probably better off getting a fit first.

Well after less than a month, the my Quarq Dzero has developed a fault and needs to be replaced...... Not very happy.

I think it's fair to say that all power meters have there faults and none are 100% reliable, not matter what people say.

I'm beginning to think i may be the only person in the country with a gen 1 stages, that works - its 4 years old, has done a stack of miles - never been replaced. I might offer to sell it back to them !!

That isn't very common though.

After a few weeks of discussing with Wiggle and as they don't have any stock (in fairness, neither does anywhere else), money has been refunded and I've switched the BB to run my original crank set.

Guess that is the problem with crank based systems, if they aren't compatible with your original BB and they develop a fault, you need to change your BB.

I'll be ordering another unit when somewhere gets them back in stock.

Changing a BB is a 1 minute job on most bikes, though admittedly an additional cost.

Agreed, if you have the right tools (or a friendly LBS).

Would Quarq not send you a replacement unit direct?

Have a look at the Powerpod.

It's claimed to be as accurate as pedal based systems and is less than £300.

I have had a look at those and at £250 (from probikekit), it's tempting, however, as it works on wind resistance, it won't be any good on the turbo, unless I can connect my speed sensor to a fan and blow in the right amount of air.....

Slightly off topic but I have a powerpod and have found it very good until yesterday when it was all over the place. It had me producing >800w at some points (I wish) but 50 on the flat at >30kmh. Not sure what made it go wibble but hoping it sorts itself out next time...

No, had to go back via retailer (Wiggle)

Aah, ok. What was wrong with it out of interest? I've just started using one myself...

In my case that's a special tool, blocks of wood and a large hammer used vigorously!

Cycle power meters will warranty any Quarq as they're an official service center. Exceptionally quick service, and they know what they're on about. Any issues I've always sent mine to them.

Honestly don't know. I was out for a ride, chain came of the inner chain ring, I put chain back on and power reading was 9697W..... When I recalibrated it, the offset was -1000 ish rather than the normal 200 ish.

Contacted Quarq and they asked me to reset the unit (which didn't work), so returned it.

Hopefully yours will be problem free.
