clean solution for multiple bikes. Many of which always break, are overpriced, or have severe flaws. Sometimes a straight 12 hour day. The laces: I?m thinking the guys complaining about laces might be pulling a bit hard, they seem fine to me - then again, I?ve had them for just a week. Update: the 2nd charger died after only one use. Calls can be rejected from the watch. The resistance also seems pretty high to me even on the lowest setting, but since this is the first trainer I?ve ever used I have nothing to compare it to, and even as out of shape as I am I can still ride just fine (just not for very long lol). Ill update my review if anything changes. Its a big headset and it sounds great. Nobody by these, couldnt even get a refund.
