Don’t buy parts until you check they fit.

Check parts against modern compatibility standards to avoid expensive mistakes.

  • Checks T47, BSA, UDH, and proprietary standards
  • Checks tire clearance, chainline, and axle spacing
  • Compares prices only after checking fit
COMPATIBILITY WARNING
Status
NOT COMPATIBLE
Conflict
Drivetrain / Freehub Body
Reason: You have selected a SRAM Eagle 10-52t Cassette (Requires XD Driver), but your DT Swiss 350 Hub is configured for Shimano HG.
We check this automatically while you build.
COMPATIBILITY NOTICE
⚠ May limit tyre choice
This wheelset limits tyre clearance to 28mm. Consider this before buying if you plan to run wider gravel tyres.

How it works

1

Add parts to a build

Select frames, groupsets, and components. We track the technical specs that determine fit.

2

See warnings instantly

We flag incompatible standards (like road shifters with MTB derailleurs) in real-time.

3

Check before you buy

Once your build is green, compare prices across major retailers.

Compatibility, not guesswork.

Retailers won't warn you if a PF30 bottom bracket doesn't fit your BSA frame. We do. This tool is designed to stop you from ordering the wrong part.

Handles Modern Standards

Checks drivetrains (mechanical, Di2, AXS), frames (headsets, bottom brackets), and wheels (axles, freehubs).

Avoid Returns

Shipping a wrong wheelset back costs time and money. Checking your build here takes seconds.

A mistake costs hundreds.
Checking here is free.

Check your build list for compatibility errors before you buy.
