I am aPowertap G3 user, so I expect mine to last until I get a disc bike. At that point I am screwed! Geez I wish the Brimm Brothers pedals had come out on time.

My PowerTap lasted six years and about 20-25K miles. I rode it in the rain, also used it for cyclocross, and didn't baby it at all. I replaced the bearings once. It just died a couple months ago. I was going to repair it but saw the GS hubs on sale for $299 and just decided to go new.

We have one powertap that has well over 30k miles and still working great. Granted, I have taken it apart every single season to clean it and relube all surfaces. Bearings was replaced as well, but it's still as accurate as it was day one.

We have a total of 5 Quarq's that all. One failed (was the first model they released) but was replaced under warranty. The other 4 are still working great.

"Suddenly the thought struck me. My floor is someone elses ceiling"-Nils Ferlin

I've had an SRM for pretty much exactly 4 years to the day. It is threads like this that make me glad now it's all paid for that I went the extra. It has not skipped a beat in those four years, and I have ridden it all year round through the British Winter, up and down cols, through Ironmans etc etc. I don't have an exact figure as to what distance I have put on it, but it must be in excess of 25,000 kms I would have thought by now.

As for the battery, still on the original. It is recommended I think to change it out every year, but I haven't and it's still going strong. I keep thinking it must be due for a swap out soon, but it is like the cockroach of the powermeter world, this thing just simply will not die!

In contrast, I brought my GF a stages 105 last year and it worked for about 2 months before crapping out. Haven't been able to get the thing to come to life since. Reminds me actually, should probably get that back before the warranty runs out next month...

Do they do a full service or just a battery replacement? If so, that probably has a lot to do with why they last so long. Especially since you 'have' to send it in every once in a while

They do a thorough check of the strain gauges, wiring and that it is watertight, along with a few other checks.

How much of a discount are they offering you? Perhaps there's someone who wants to buy a new Quarq that would be willing to split the discount with you.

Exactly what I have. Not done 60k on it yet, but I've had it for 3 years so far (purchased lightly used off ebay). I have no idea how long the battery would last, as I change it before my annual 'A Race' just to be sure!

29 years and counting

Well as of today i can say my quarq made it 2 yrs to the week almost. Last 4 weeks I its been dropping power, over or under reporting it, finally took it into LBS. Guy in service told me 2 yrs zero issues is pretty damn good and he thought its more about how company handles it when there are issues.
Called Quarq today and they made it about as simple as ever, got numbers off my Elsa RS and they are shipping new one out to Kona for me. A+ for quarq customer service.

2024: Bevoman, Galveston, Alcatraz, Marble Falls, Santa Cruz

I have a powertap I bought used in 2013 and I think it was at least 2 years old at that time. I have had to have the wheel rebuilt but the PT is fine. I ride it on every ride 4-5 times a week

Conversations like this are the reason why I don't own either a powermeter or a smart trainer. I simply can't stomach the disposable nature of products these days. I had a zipper break on a seldom-used 2y old rain jacket last week and I requested (and received) a warranty replacement from the store. I'd be gutted to be stuck with a $1k+ useless product.

I currently use a wired Powertap (free, long term loan) and a >15y old Magura trainer (hand me down in 2003). I think the trainer might finally be broken though. Thanks for talking me out of spending $$ on a smart trainer. :)

I have two Quarq Rikens that are about 3 years old. Both have worked flawlessly. I replace batteries - cheap and easy to do - and that's about it. I'm expecting them to last for many years to come.

So.. I finally returned the bike and good news! Even though it was out of warranty quarq replaced the unit. I have it back and it's working great!!!

Never had a powertap make it through a full season. On my fourth one now. Relegated to the TT bike to try to extend its life.

Have the c1 and it's 8 months strong. Hoping it continues.

Have a 10 or 15 or however old SRM V that I could probably run over with a train and it'd keep trucking along.

My original type Vectors have had nothing besides batteries. Very happy with them and would buy them again. Rain doesn't seem to affect them.

Surprised by Quark, I had always thought they were meant to be good.

My first SRM is 13 years old and a friend is still using it. I have two DA SRMs from 2005 and 2006 (with PCV) that are still going strong. My Powertap G3 I bought a bit over a year ago went through two sets of bearings within 9 months and is now in the bin as the 3rd set was going. Back to Rotor SRM with a PC8 and it's been flawless for past 8 months.

My only other experience with Cyclops was there Powerbeam trainer which never worked even with a new resistance unit. Never one of their products ever again.

i know your post is from a couple months ago, but this thread just got bumped and i noticed it. i figured i'd correct the misinformation/misperception:

SRMs solid since 2012 (and possibly a bit earlier) all have longer battery life. it used to be that one could expect about a year or 2 from their battery; thus, the need to send it in and have it checked out while the battery was being replaced.

however, they beefed up the battery life quite a bit -- up to 3,000 training hours.

sure, people who own older units still send theirs in every year or two, but every units sold these days has a much longer service life. the shimano DA units, for example, only need to be sent in every four years if you are riding 60+ hours a month, 12 months a year.

Just had to return an 18 month old Powertap G3 under warranty for torque tube/bearing/freehub replacement.
Wheel gets used about 10 hrs a week with 95% on the turbo.
Bit disappointed it needed to have this done (but now happy it's pretty much a new hub) but have to say the service and turnaround by Cyclepowermeters in the UK was outstanding.

That is the only thing keeping quarq viable, phenomenal customer service. I have been through three units, but always fixed or replaced expediently free of charge. I do think quarq is getting better, my newer unit has 2 flawless years so far. I am going to give the new d zero a try.

My oldest SRM (Track unit +PCV) is now 14 years young and works perfectly well and is still serviceable if/when required. My "youngest" SRM (+PC6) is 7 years on and works just fine as well. I have 2 others in between these ages and they work just fine as well although haven't seen much action recently. When the man cave is finished then the trainer will be set up and one of them will see more service.
