Unlock smooth shifting performance with the ultimate upgrade for your Shimano HG Hollowtech bottom bracket, cassette shim, and wheels. This precision-engineered spacer kit is specifically designed to fit into the standard bottom bracket cups of most high-end bikes, providing a seamless transition between gears and wheels.
The modular design allows you to easily install new or swapped bottom brackets without compromising ride quality or shifting performance. The 0.7mm shim provides optimal clearance for low-rider designs and aggressive gearing configurations, while the 4mm shim accommodates thicker cassette spacing for high-performance bikes.
By upgrading to this top-quality spacer kit, you'll experience improved wheel-to-gear ratio, reduced drag, and enhanced overall bike handling. Compatible with Shimano HG Hollowtech bottom brackets on a wide range of high-end road and mountain bikes, including those from Pinarelta, Trek, and Specialized.
