Significantly improves work efficiency! <Features> ・L-shaped injection nozzle: Attaches to the tip of Shimano roller brake grease 100g, allowing for smooth injection even in tight spaces. ・Cap removal lever: Catches the cap during removal to prevent loss. ・High-quality design: Made of durable PETG material, repeatedly improved for ease of use. <How to Use> Use the tips of the cap removal levers to remove and attach caps. Attach the L-shaped injection nozzle to the tip of the Shimano roller brake grease 100g. Inject the specified amount of grease as shown in the image. The tip of the injection nozzle is delicate, so hold the grease container and nozzle firmly with both hands to prevent misalignment or damage to the injection port. <Notes> Cancellations and returns due to buyer's circumstances are not accepted. The roller brake body and roller brake grease in the images are not included. Not tested on all bicycles. We will not answer inquiries regarding compatible bicycles. Both the nozzle and lever are designed for a minimum gap of 6mm. Not compatible with plastic cap models (likely models from the 1990s or earlier). Not compatible with Hyper Roller Brake BR-C3000 series, which has the injection port on the bottom. Forcing use may cause damage or injury. Use protective gloves and safety glasses during work. Caps can become very hard due to cold or aging. When removing hardened caps, use a flathead screwdriver to assist the tip of the removal lever. Follow the instructions in the brake body manual for the amount of grease to inject. Due to being 3D printed, a unique striped pattern may be visible.
