Garmin Edge 850 cycling computer review: brilliant in almost every way

Garmin Edge 850 Cycling Computer.

Garmin is the OG of GPS cycling computers, having forged a reputation built on reliability, metric tracking, and navigational excellence. The Edge range of the best bike computers is improving with every iteration, but mounting pressure from rival brands Wahoo and Hammerhead, as well as outliers Bryton and Coros, is eroding its positioning within the market.

With its new Edge 850, Garmin is looking to win back lost votes, but will features borrowed from the range-topping Edge 1050 really do the trick, or has the company merely attempted to over-engineer (and overprice) one of its most popular devices to stay relevant?
