Racers take note! With the Chris King bottom bracket and injection tool, you can train day-to-day with a durable high-viscosity grease and race with a light, fast-rolling low-viscosity grease or oil. Imagine your current Friday night leg-shaving ritual finishing with a few minutes in the garage to get your bike as smooth as you are.
