Compare bike parts by hard specs

Put offerings side by side to see which parts are lighter, which actually fit the bike, and how they compare on price.

How to use

Filter, sort, compare

01
Pick a type
Open Bike Components and choose a live category — cassettes, rear derailleurs, cranksets, forks, or rear shocks.
02
Filter by fitment and discipline
Narrow to parts that match the bike: interfaces first, then mtb, gravel, road, or TT/tri.
03
Sort and compare
Sort the table, then line up up to three offerings on weight, fitment, and price.
