StarStarStarStarStar Worked great for second bike

Ownership: several months
Tech Knowledge: somewhat high


Easy to configure
Transmits far enough for a short wheel base recumbent.


Requires a special tool to change the batteries. I took a spare set of batteries on tour. Since the batteries come pre-installed I didn't notice a special tool was required to change batteries. Another rider with a Rox computer had a failed head unit battery. He couldn't use my spare since neither one of us had the tool.

Other Thoughts

The Rox 6 is a great bike computer.

StarStarStarStarStar I love my sigma

Ownership: a month
