Top Cap

What more is there to say than it’s a top cap? Well it’s a 100% unique top cap, designed in Ireland and machined from 6061 aluminium. Like all of our products, they’re supplied with stainless steel hardware so no rusty bolts. It’s also a featherweight at just under 6 grams for the top cap.

Available in 7 colours to match our existing stems and bashguards!

Three Rock Components

Starting in 2021, Three Rock Components came from the deram to make my own mark on the cycling industry, rather than simply follow suit. After more than a year of testing and development, we launched our first product in July 2022.

Products like our signature one piece stem, chainrings, seat clamps and bash guards are only the beginning. There is always more work to do and more improvements that can be made!
