The things that are just as important as the components: professional tools. Shimano tools are shaped to fit Shimano components perfectly. The tooth profile corresponds exactly to that of the components, including consideration of tolerances. The latest silver or black tools (TL-HS33/34/35/37/38/40, TL-FC 36) are laser cut to achieve a maximum smooth surface that is designed to eliminate the risk of damage to the parts.
