The Ultimate Bike Weight Calculator

Bike Champ is the ultimate bike weight calculator designed for riders, builders, and weight weenies. Whether you are planning a lightweight XC race bike, a rugged MTB trail build, or a custom gravel race rig, knowing your total weight before you buy parts is critical.

Unlike generic spreadsheets, our custom bike builder tool allows you to select specific components—from frames and forks to cranksets and saddles—and instantly see how every gram adds up. We track weights for major brands like Fox, RockShox, Shimano, SRAM, and boutique manufacturers to give you the most accurate bicycle weight estimate possible.

Why use a Bike Weight Calculator?

• Plan your dream build: Visualize your total weight in kg or lbs before spending a dollar.
• Compare Components: Quickly swap between a Fox 34 and a RockShox Pike to see the weight penalty.
• Track the details: We include often-forgotten weight like shifter cables, dropper housing, and tubless sealant.
