Bike Geometry Database – Free Tool for Cyclists, Fitters, and Bike Shops

Find the perfect bike fit with our free, easy-to-use Bike Geometry Database. Whether you’re a rider searching for your next bike, a fitter dialing in a client’s setup, or a bike shop comparing models, this tool helps you quickly compare geometry specs—especially stack and reach—across all major brands and bike types.

What is the Bike Geometry Database?

The BikeFit Systems Geometry Database is a growing library of frame geometry data across all categories—road, gravel, MTB, triathlon/TT, e-bikes, touring, and more.

Use it to:

  • Filter stack & reach
  • Compare bikes across brands and types
  • Access detailed specs for each bike model

Who is it for?

  • Riders: Compare frames and find the best fit before you buy
  • Bike Fitters: Use it during fit sessions to match coordinates
  • Shops: Quickly reference models for sizing or spec comparisons

Why Stack and Reach?

Stack and reach define a bike’s fit and feel more accurately than traditional sizing.

  • Stack = Vertical height from bottom bracket to top of head tube

  • Reach = Horizontal length from bottom bracket to head tube center

Use these to compare bikes evenly across different brands and frame sizes.

Brands and Categories

We’re constantly adding bikes from the most popular brands:

Specialized, Trek, Merida, Cannondale, Giant, Scott, BMC + More coming soon…

Each bike entry includes all available sizes and gender-specific variants.
