Im curious to know why some of you swear by the Quarq DFour 2 power meter, citing its accuracy and reliability as the main reasons, yet others claim that its overhyped and overpriced. Can someone explain to me what makes this power meter so special, and whether its truly worth the investment for a serious cyclist looking to take their training to the next level?
Is it the fact that its a crank-based power meter, or is it the claimed accuracy of +/- 1.5% that sets it apart from other power meters on the market? And what about the reliability - are there any documented cases of the Quarq DFour 2 failing or giving inconsistent readings, and if so, how common are these issues?
Ive also heard some rumors that the Quarq DFour 2 is more prone to calibration issues than other power meters, and that it can be finicky to set up and install. Can anyone confirm or deny these claims, and provide some insight into what its like to actually use the Quarq DFour 2 in real-world training and racing scenarios?
Lastly, Im wondering why some of you are so quick to recommend the Quarq DFour 2 to new cyclists, despite its relatively high price point and the fact that there are other, more affordable power meter options available. Is it really worth breaking the bank for, or are there other options out there that can provide similar performance and accuracy at a lower cost?
