Mountain Bike Coaching Q&A: Frame Sizing, Suspension, Setup & More
Getting the right mountain bike size isn’t guesswork—it’s science and coaching combined. In this GSMBC guide, we break down how to measure frame size, match bike fit to rider height, and choose the right wheel size for confident, efficient riding. Whether you’re fitting a 10-year-old on a 24-inch bike or coaching a 6-foot rider into a large 29er, proper sizing builds comfort, control, and skill progression. Grounded in GSMBC’s Reference Guide and Advanced Coach FLOW framework, this Q&A covers everything from seat height and handlebar setup to suspension tuning and common fitting mistakes. Written for coaches, instructors, and riders across Canada—especially those training on Whistler’s world-class trails—it’s your complete resource for teaching bike fit the right way.
