Components

Fine-tune and lighten your bike with performance carbon and alloy components. Underdogs Cycling stocks finishing kit and drivetrain parts from brands including Elilee, Overfast, LiteTech, IMTOS and S-PARTS — the details that sharpen how your bike rides and looks.

From integrated handlebars and cranksets to chainrings, power meters, thru-axles, headset spacers and saddles, you'll find weight-saving, race-ready upgrades built to modern standards and broad compatibility.

Everything ships factory-direct — genuine performance parts at honest pricing, with warranty support and tracked worldwide delivery. Component compatibility (BB standards, BCD, steerer and axle dimensions, freehub type) matters, so if you're unsure whether a part fits your bike, send us your frame, crank or groupset details and we'll confirm before you order.
