CrankSmith: Bike Project Build

Stop guessing if parts fit. Build your dream bike virtually with the world's smartest compatibility engine. Validation for Road, Gravel & MTB.

Building a bike shouldn't require a spreadsheet and five open tabs.

CrankSmith is the ultimate toolkit for cyclists who wrench. whether you're planning a dream build from the frame up or just upgrading your groupset, CrankSmith ensures every part works together perfectly.

THE COMPATIBILITY ENGINE Never buy the wrong part again. Our advanced validation engine checks thousands of data points in real-time: • Drivetrain Matching: Mix and match shifters, derailleurs, and cassettes without fear. We check pull ratios, protocols (AXS/Di2), and capacities. • Frame Fit: Automatic checks for bottom bracket shells (BSA, T47, PF30), axle standards, and tire clearance. • Wheel & Tire: Verify internal rim width vs. tire width safety and clearance limits.

VIRTUAL BIKE BUILDER • Visual Spec Sheet: See your entire build in one clean, professional dashboard. • Weight Weenie Calculator: Automatic weight estimation based on your selected parts. • Price Estimator: Keep your budget in check as you swap components.

COMPONENT DATABASE • Instant access to specs for thousands of parts from Shimano, SRAM, Campagnolo, Enve, Zipp, and more. • Compare similar parts side-by-side to make the best choice.

GARAGE & GUIDES (Coming Soon) • Save multiple builds. • detailed technical guides for standards like T47, UDH, and centerlock.

Why CrankSmith? Modern bikes are complex. Proprietary headsets, 12-speed distinct standards, and electronic integration make compatibility a minefield. CrankSmith decodes the chaos so you can focus on the ride.
