The team at Quarq are decidedly science geeks. The Spearfish, S.D., company was named after the quark, the elementary particle that has never been observed or isolated. The DZero detector involves an intense search for subatomic clues that could reveal the building blocks of the universe. It’s one of the world’s most sensitive and accurate devices — just like Quarq Power Meters.

Ideal power meter
Having used this now for a couple of months, the Quarq power meter is excellent. It took a few rides to settle down but now appears to be accurate. If you want to train with a power metre, then I would say go for this one. I've tried the one sided pedal meters and they are OK. However the Quarq measures both sides and has allowed me to correct a discrepancy between left and right power. They are now more balanced and I'm riding stronger. It's an expensive bit of kit but in my view worth it.

Simple installation. All spacers and washers are in the box and clearly labelled. Instantly working after installation. Seems rock solid and very stiff. Numbers seem totally on point. Zero issues.

It is compatible with sram etap ?
Thank you for your question.
This would be mechanically compatible, as it will work with 11-spd chainrings.
Hi I am looking at this Quark power meter to fit to my 2017 Cannondale Synapse Ultegra disc. Will this meter fit thei bike, with the Cannondale IS rings and bottom bracket?
Unfortunately we do not Sell Cannondale so i cannot fully answer your question. From what i can see online, Yes this will work however you may need to add some spacers to correctly adjust the spacing of the chain-set.
