  1. 7 Speed cassettes require a spacer to eat up extra width (approximately 4mm) of the hub body since it is 4mm narrower than 8-10 speed cassettes.
  2. Does not include adapters, nor is it convertible to any other axle type
  3. Centerlock hubs have advantages that 6-bolt hubs do not. They are compatible with either type of rotor. There are no bolts holding the rotor on - no snapped off bolt heads leaving behind a diffult to remove remainder of the bolt, no throwing your wheel away due to a stripped bolt thread, and faster installation. However, centerlock to 6-bolt adapters must be used if using 6-bolt rotors. These are NOT included with the wheelset.
  4. Ball / Cone type hubs are the most common type of hub on planet earth. While being nearly indestructable and serviceable, optimal performance requires maintenance. If you're looking for optimizing performance, we advise that the cones are adjusted to your preferences, as well as checking cone position, and re-greasing the bearings throughout the life of the wheel. See the last image for a general diagram of this type of hub. The closer the two cones are on either side of the hub the more restrictive and poor the wheel will spin. The farther the two cones are apart, the better a hub will spin, however, it may introduce play/slop into the bearings if they are too far apart. The perfect position is where the axle turns with the least amount of resistance, and has no extra space between the cones, bearings, and hub races (has no slop or play). The lock nuts on either side of the axle lock the cone's position in place. It is not unique to our brand of wheels, but the design of ball / cone type hubs. Generally, the folks at the factory err on the side of too tight rather than loose because being slightly too tight is better than too loose. Adjustment usually requires one cone wrench (thin wrench), and a standard box/open end wrench for the locknut. There are loads of videos on youtube describing the process.
