BC1606LSIGMA’s top model for the most demanding, even at night.
The Sigma computer for dedicated cyclists. The "L" in the BC1606L is for the "smart" back light. The cadence functions (current and average) provide valuable training data for efficient cycling both on the road and in the woods, and can be turned off completely when not in use. The count down timer is perfect for crits, cross, or racing against the clock.
