Serious cyclists, listen up.

This Hope Technology bottom bracket is built to perform and last.

It's designed for cranks with a 30mm axle and fits a bunch of common shell widths: 68mm, 73mm, 83mm, 100mm, and even 120mm for fat bikes.

The magic is in the details.

The cups are machined aluminum and house high-quality, replaceable stainless steel cartridge bearings.

Why stainless?

Way less friction and a much longer lifespan than the stock bearings that come on most bikes.

It's got a free-running labyrinth seal that keeps dirt and grit out while adding minimal drag.

At only 102 grams, it's light but tough as nails, suitable for everything from road riding to downhill mountain biking.

Oh, and it comes in this awesome purple color (other colors available too).

Just a pro tip: you'll need the specific Hope fitting tool (HTT188) to install it properly.

If you're looking to upgrade your bike's drivetrain efficiency with a component you won't have to replace every season, this is a solid investment.
