Was having trouble with my speed sensor due to the wheel magnet slipping. My son had these and I thought the design was better than the common magnet-and-sensor variety. Installed easily, paired quickly with head unit (Karoo 2), and has been trouble-free since. Cannot ask for more!
Finally, a cycling computer that doesnï¿½t feel like it was designed using technology 5yrs in the past. Touchscreen on the 1040 is super responsive and it has all the training features you would ever want. I am coming from a Edge 530, so my only complaint is that it is significantly larger, so youï¿½ll need to account for that when mounting. BTW - from reading reviews, unless you are doing seriously long rides and will not have access to power, the solar version isnï¿½t necessary.
A lot of bike tech these days seems like overkill but that's not the case with this. It has made my commute safer and I wouldn't feel as comfortable riding without it. I use the Garmin 530 and the ap on my phone. I keep one earbud in while riding to get the sound alerts. I love the color sequence that it goes through: orange means a slower vehicle, red means a faster vehicle and green means all clear. After using since last May to commute, I can honestly say I have yet to see a false positive or negative. The only issue I had was my old pannier system blocked the sensor. so I had to swap that out. Otherwise, this thing works flawlessly and makes my daily commute safer. I hated the small mirror I used to use on my bar end which was way to distracting.
I am training for a 70.3 Ironman race and had to improve my performance. The data feedback given by a 2 pedal setup helped me understand how I pedal and how I can improve my performance on the bike. For training, I can easily follow a cadence/wattage tempo workout and get away from HR workouts. Knowing my FTP and training to it has been an upgrade to my workouts and performance on the bike.
