For a limited time, almost everything on the site is 30–50% off. Kolossos cages, bottom brackets, pulleys, and accessories—if it makes your bike faster, smoother, or quieter, it’s marked down.

Plus: Spend $100+, and we’ll throw in a free bottle cage. Just add it to your cart, and the discount applies automatically.

It’s the once-a-year moment where upgrading your drivetrain is dramatically cheaper. Whether you’re refreshing worn parts or building something new, now’s the time.
