Quarq vs. Powertap?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Quarq vs. Powertap?

I am upgrading my Tarmac this seaons and will most likely be getting SRAM Red for it. Once I'm there, I'm thinking of getting a Quarq powermeter (the cranks) for the bike. I like the idea of the Quarq since I have a couple of pairs of wheels and this way I can switch easily. Also, it's lighter than the power tap.
Are they good? Are they as accurate? Reliable? Anyone use one here?
lastly, who uses what in terms of the head unit? I kind of like the cycle ops one and then the garmin 500.
Thanks

I love my quarq. I've race it in the rain, ridden in the winter and crashed it once. Still works. Have a Garmin 500 which is fine. Make sure you get the correct crank for the correct BB.

sample size = 1

There's a long thread in the racing forum about Quarq v Powertap v SRM, worth reading.

Personally, I like the Quarq. I have a powertap and a Quarq. Running them side by side they were very consistent in results.

As for reliability of the Quarq, I've had mine for 2 plus years now, and have had no significant problems.

The quarq allows you to run whatever wheels you want. Also, as long as the BB's are compatible, you can switch it from bike to bike in just a couple of minutes.

The Quarq is great. I have both. No problems with either.

Run both and sell both. If you have the money to step into it from the start then the Quarq Cinqo is probably the best route to take for sure. I sell far more powertaps for sure, but that is most likely due costs/pricing. If someone doesn't have any nice wheels to begin with and wants nice wheels AND power training it is probably a better route, but if you have a nice setup and plenty of wheels to choose from then the Quarq makes better sense for sure.

Data between the two - I find that the Quarq give me "smoother" response even using the same sample averaging. Raw data - both are very comparable and within about 5W of the computrainers I run as well.

Thanks for the info guys.

What your opinions on SRAm Red vs the FSA K force Quarq cranks? I don't see weight on the Quarq site. ANy difference worth choosing one or the other?

I've had mine for ~2 years or so. It has worked very nicely for me. I had a firmware issue that was resolved quickly (had to ship it to SD) with postage paid.

Also, just wanted to clarify that the SRAM cranks that Quarq uses are the S900 and S975. Reportedly, the S900 is "force-level" and the S975 is "red-level". The only difference being a "non-integral" spider for the Quarq offerings.

I have a PowerTap. I wish I had a Quarq - I don't get power numbers when I use my race wheels, and that can be frustrating.

That said, the PowerTap is great, and has been the last three years. I've had zero issues or problems.

it's a confusing naming situation.

S900/950 refers to the crank with removable spider. 900 being the standard and 950 being the compact. You make it "red level" by adding the red chainrings, which are actually heavier than the force/rival chainrings, but allows you to run things like a 52/36 or 54/42

The force rings are lighter? How come? Are the red's stronger/tougher?
I think I'm going to take the plunge... Anyone like the FSA cranks better? Lighter?

When I raced I had a powertap on my training wheels. I always hated it when I finished a race and I didn't have my numbers to review since my Zipps did not have a powertap.

I now have a SRAM quarq and I am very happy with it. I can run whatever wheels I want. It is very easy to switch the crank between bikes but I decided that I don't want to so I just placed an order for a powertap for my spare bike. Now I will have power on both bikes and I won't need to change anything.

If I was just going to have one it would definitely be the quarq. With that said, the powertap I just ordered will be my third powertap. They are both great products.

Are you going to do another Quarq group buy? Missed the last one

Another one to consider is the SRM. I found a used wireless compact version with the PC7, complete for 2150 on Ebay. Of course I hear the Quarq is good as well. If you go with the Quarq it can be 1900 if you know where to avoid getting taxed, but don't forget the cost of a head unit and the accessories if you do not already have them. That can be 330 if you go new on the cheapest route.

I'm happy with my Quarq 975 and Garmin 500 head unit. No issues, and I love it.

You can get a new quarq for under $1,800 on Amazon.

I also have both. Love the Quarq S975 with Red rings. I have compact and 52/36 rings I can put on it. I still want Qalvin to recalibrate it myself when I switch.

I now have three powertap wheels, really wish I had gone the crank route but, that would not have worked out 100% either since my road bike is 172.5 and the TT bike is 175, sure I could pull the spider off and make the swap that way but at the end of the day...

I just had to google "Qalvin" - boy that would be nice. If I got a Quarq, I'd definitely be changing rings (primary uses would be ITTs and cross races). Not having to send the crank in for recalibration would be a big inducement to get one for me.

I think there's a decent chance they come close to that target. I don't think Garmin, as a public company would be throwing out forward looking statements without something to back them up.

I'm waiting to pair my Edge 800 with Metrigear. If they take too long, I may have to go with Quarq. Late 2011! WTH!!
