Less weight is just the start...

We offer the widest selection of properly matched sets. Also, some customization is available. Don't settle for the gear range that's only partially what you need .

CNC machined shift ramps and beveled teeth help give great shifting performance. We cut our own precision spacers for perfect indexing.

We use the most accurate process for making sprocket teeth - gear cutting. Gear cut teeth give a perfect tooth profile, smooth and accurately cut across full width of cog. Edges are square, providing maximum support for the chain roller and the most efficient power transfer. See what's gear cutting.

Cycle Dynamics mission is to make the most efficient, highest performance bicycle cogs - and to do so cost effectively. Cassettes and chainrings are all we manufacture.
