Disadvantages:
1. Temperature is inaccurate. Today's weather is a maximum of 2 degrees Celsius, but the Garmin 850 displays 5~8 degrees Celsius.
2. Battery life is likely to be a maximum of 11 hours.
3. There are still very few data fields available on Connect IQ.
4. The weight is a bit heavy..ㅠ ㅜ (compared to the 830).
Otherwise, it seems better than the 830. So I'm thinking about selling the 850 and using the 830 again.
Disadvantages of ASSIOMA PRO RS2:
The pedals don't turn in winter..ㅠ The grease is cold, so it seems like that's why.
The existing Look version was too tight to put on, so I was satisfied with the RS2, but this problem arises in winter....
Otherwise, I don't know much.
Please refer to it for purchase..
