Hi and thanks for any input! I just purchased the Garmin Forerunner 570 and a chest strap, I want to improve my distance and speed on my bike (Specialized Sirrus X 5.0- will be buying a designated road bike for spring) and will be dabbling this winter with a fat tire bike in the snow. What is a good Bike Computer for my goals, I also will mention I do not plan on buying the power meter pedal. I am debating on buying the speed and cadence sensors. I am new to taking biking seriously and currently can manage 40 miles at a speed between 15-18mph. My goal would be to maintain 20mph for 50 miles. I appreciate any suggestions!
