How fast, how far, and how long? Bontrager's Trip 2 computer displays current, average, and maximum speed, current and total mileage, ride time, a clock and temperature. The Trip 2 is all about versatility, too, it records data for 2 wheel sizes so you can use it on your road and mountain bikes and you can mount it to your bars or your stem. The Trip 2L model has an extra-long wire for rear-wheel mounting, which is great for use with trainers.
Purchased new August 2014. Accurate and functioned well initially. After 2 1/2 months began to act erratic on speed and odometer/trip, then quit. Replaced battery and it functioned again for 2 days, then stopped. Now accurately displays time and temp only. Other reviewers on various websites have had similar experience
Bottom LineNo, I would not recommend this to a friend
