This is the Bombshell BMX wheelset that brought Maris Strombergs his Olympic gold medal.
Two specialty Park bike tools are required for tightening (FR-5) and loosening (both tools). The HCW-16 is a chain whip tool that holds the cog or gear cluster from moving while you loosen it. Only the FR-5 is needed to tighten the gear. The gear is not tight when you receive it so that you can easily change gears for your individual riding purposes.
The HCW-16 is also a 15mm pedal wrench.
"SL" wheels make a bigger difference in more ways than ever. Bombshell discovered wider rim increases lateral stiffness for sprinting and cornering yet offers greater vertical compliance for more control, comfort, and durability on rough surfaces. The wider design better protects tires and places more rubber on the track while cornering without adding rolling resistance. Includes the SL hubs with female bolts.
Tighten up your cog (gear) before riding. The HCW-16 is also a 15mm pedal wrench.
