Frequently asked questions
How fast should I be cycling at 200W?
On flat road with no wind, 200W typically produces 30-33 km/h for an average rider. Add headwind, extra weight or gradient and speed drops significantly.
What gear ratio should I use for climbing?
A 34×28 (34-tooth chainring, 28-tooth sprocket) gives a ratio of 1.21:1 — very easy for steep climbs. Most modern compact road groupsets can achieve similar low ratios. Match your gear to a cadence of 80-90 RPM for efficient climbing.
