Mieke from Quarq here. You are correct, the CinQo power sensor uses similar strain gage technology as the SRM and Powertap. We are essentially just replacing the spider with the power sensor, which is basically what SRM does. The CinQo has 10 strain gages and adds about 40-60 grams over the replaced stock spider's weight, depending on the version.

The CinQo samples the combined torque from both legs at 60 Hz which is averaged per revolution. The data packets are sent wirelessly, via the ANT+Sport network, to a compatible head unit at a rate of 4 Hz. They are updated once per revolution.

Current compatible head units are the Garmin Edge 705 and the iBike iAero. We hope to have our Qranium computer available sometime this fall.

For what it's worth, we saw this yesterday on the Google Wattage list regarding Ergomo: https://groups.google.com/group/watta...5eb42e1788463#

My personal opinion is that you're probably best off sticking with a strain gage based system such as ours, Powertap or SRM.

Looking at the action pics almost makes me want to hire a personal coach. Operative word being "almost". Good luck with your training and racing.

Hermes

Hey guys...think no more and pull the trigger. I did not buy the last one.

George

Yea, but I just bought the Roubaix.

Hermes

Hi Mieke:

We are looking forward to later this year when you have sensors for compact cranks. Thanks for the technical scoop.

I'll be retired next spring and plan to train and race "full time". I'm thinking retriement present. My wife will be retiring also after teaching 31 years and she's expecting a European Vacation. I can see it now, me riding my new Cevelo R3 on a TDF stage route while she waits to meet me at a little roadside cafe with wine and bread.

Hermes

I like the way you think. Good luck with your racing and training.

I was leaning towards the R3-sl but like the white better. Other than color and maybe weight, like a few grams matter when I'm overweight, are the differences?

Hermes

I rode both the R3 and the R3 SL and talked with Cervelo. The R3 and R3 SL are identical in performance but the SL frame is 90 grams lighter.

Thanks for all the pics; they are great looking bikes.

There's a tour company called "Exodus" with many wonderful adventure vacations. One is "Great climbs of the TDF". All the vacations have less demanding options and alternatives for people who want to come along but maybe don't want all the challenges. I'm not on their payroll (!) but I've done a couple of their tours, and I'd recommend them. Happy googling, and have a wonderful retirement!

As long as the "dream" gets you past just buying the bike, no matter how much you have bowed to the marketing gods, and into actual riding, that's a good thing.

That is a beautiful bike collection! It's also great to see them in the hands of folks that put them through their paces, not just admire them. Enjoy the ride!

Hi Hermes,

Very nice bike.

I keep thinking that I want to try a Cervelo. I've always liked the way all of their models look. The only thing that worries me is that the top tube is too short. Otherwise the geometry looks great to me.

BTW, I was talking to my friend Laura L. the other night and she told me that she won the Masters Women road championships in NorCal a couple of weeks ago. Was velodiva in that race?

Hermes

Yes, Velodiva raced and came in 4th. By the time she raced, it was hot and her feet started to hurt after lap 2. She has Morton's Neuroma and could not put any pressure on the pedals for the final lap. Laura L was in top form and looked great. Her husband and I raced in the 55+. I blew up on a climb. There was a lot of smoke in the air and we were both coughing until Tuesday.

As with most of these bikes, you have to try it to see if one of the sizes works. I really liked the ride of the R3 compared to the other bikes I tried but it is a very fine line in that class of bike.

WHOOOSSHHH...

Great looking bikes!!

Hermes

I was a little (well very little) concerned about being a copy cat. White is hard to keep clean.

You always say the right things.

Here is the man on what appears to be an R3 SL. I think he rode that bike most of the time. Some of the other CSC riders rode the SLC SL.


I googled mammerjammer and I will use it sparingly. It is and I will.

That day was the Giro de Peninsula and there was automatic camera set up on the road. I was not on the ride but when I went by is snapped my pic.

Hermes

A coach is a great way to take your riding to a new level. It is very tough to build the engine on your own. Clearly, one can just ride and get great results. If you want to build the engine fast, it takes some third party expertise and feedback to keep you on track and out of trouble.

Hermes

Thanks to all for the kudos and encouragement.

I was thinking about your beautiful stable of bikes this morning while riding my bike in to work. I don't know which of your bikes is the prettiest, fastest, lightest, or best suited to its intended use.

However, I am pretty sure of this: if you handed each of your bikes a knife and a broken beer bottle, and sent them into a dark alley to fight it out, only Wicked would come back alive.

That is one mean bike. Hopefully you don't leave them all unattended at night; something bad might happen to the gentler ones.

Sorry - don't mean to be critical but as an engineer I don't see how this is possible. I agree you can sense the torque on the right side but can't see how you capture the left side. If I were to only pedal with my left foot what would your system read? Call me skeptical but I don't see how you can measure torque on the left side if your sensors are not between the left pedal and the chain. Please explain - I am all ears. Since I have never disassembled a bottom bracket maybe I do not understand the mechanical linkage - does the shaft to the left pedal connect to the chain rings through the spider?

cyclinfool

Hermes - you certainly are in the 99 percential. What a great stable of bikes.

I just built and sold a R3. All Sram Red. All I got to do was ride it around the parking lot.
Very nice for the short time I had it.

Hermes

Check this out and read the SRM technical discussion. SRM professional is the gold standard for power meters but $3500 for D/A is a lot of money for electronics. https://www.biketechreview.com/archive/pm_review.htm

Hopefully Mieke will provide how quarq does it.
