Quarq owners thread
« on: December 17, 2011, 11:37:55 AM »
question #1:

which magnet are you using?

if you are using the BB-threaded ring magnet, do you notice the difference in Q-factor?

if not, and are using the glued magnet, how did the installation work out?

BB ring magnet, and i don't notice the difference in q-factor, but this may be due to the fact that my left cleat is non-float, and the right cleat is floating

I use an epoxied magnet on my tarmac. There is no room for a ring on a BB30 setup. The epoxy set very firmly and I haven't had an issues.

I used a ring on my Tricross, didn't notice any kind of q-factor difference, it's a very, very thin ring.

Ring.  I didn't notice any change.

Glued.  Not sure if it was always putty, but the putty was really easy to work with.   I tried using the cable guide mount, but it put the magnet too far outside the cadence ring.

Ring on the old bike.  Glue on the new one.  Never noticed an issue or a difference.

i've used the glued magnet on 3 frames but lately prefer the magnet that is glued to an aluminum brace that then screws into the cable guide holder below the bottom bracket, for those bikes that have a threaded hole there.

what i've learned from a few challenging installations is that the magnet is strong and does not have to be within the CinQo's ring -- i just needs to "nick" the ring in order to trip the sensor.

My Quarq is supposed to show up today, a day early  :bday: . There's no consensus on this thread. Hmmm. There's no need for me to use the epoxy, so it's either the ring or the BB cable mount. I'm going to try the ring first.

Ring, on all 3 bikes - it is 1mm or thinner - so that doesn't make any difference that my body can feel.
The magnets are really strong, especially if you double them up - I'll probably use a ring magnet on my track bike as well when I install that later in the year.

Although I thought I was out of the power meter market, I may have a contact for Quarq. I'm debating if I should try them, for a couple reasons:
1. I can use threaded English and get bearings that don't index (the BB30 thing isn't good for small builders like Tsunami). I can also put it on my track bike.
2. I can sell off two (wired) SRMs to fund a Quarq or two.
3. I can use Ant+ Sport and use the 4iiii that I've been threatened to receive gratis.

I'll have to do some research.

I rode it on the trainer last night for the first time. Setting it up was really easy. I used the BB ring. I noticed the cadence dropped out once during a spinup so I may need to add a magnet. It's going to come back off to swap chainrings so I'll check it then.

I use the putty w/my BB30 frames. Never had an issue, and while "permanent", the magnets pop right off when using pliers and the putty can be safely scraped away very easily.

I tried to add a magnet but it was rubbing the inner sensor ring, so one magnet it is. I swapped the inner chainring back to 39T and dialed the shifting in, and now it's as good or better than when I had the 7900 crank.

I can obtain different sizes of neodymium magnet (rare earth) and building up an epoxy base is also possible.
