Center Lock Vs. 6 Bolt

Six-Bolt Rotors

• Six-bolt rotors are perhaps the most common type of rotor on the market. They are easy to make and give a bike stability due to the fact that they bolt into place. The 6-bolt part of the name literally stands for the rotor's six bolt holes. The most noted advantage of a 6-bolt rotor is that it is easy to find and replace and most bikes come pre-equipped with 6-bolt rotors. Because the 6-bolt is universally used, it is ideal for anyone wishing to purchase, trade or buy a bike anywhere in the world. Replacement parts can be purchased almost anywhere. Disadvantages include slower turning speed and the necessity of a wrench to replace any parts.

Centerlock

• Centerlock (or Center Lock) rotors do not bolt into place. They are equipped with a series of sliding holes that have inset grooves. These inset grooves allow the rotor to simply be turned and locked into place. This allows for easy replacement as well as a faster turning speed. Centerlock rotors are usually lighter than their 6-bolt counterparts due to the fact that they allow for more hollowed out steel and do not require bolts. The biggest disadvantage is the fact that Centerlock rotors are not readily available at every bike shop and most bikes are not compatible with them.

Converters

• In some cases it is possible to purchase a converter so that a 6-bolt rotor can be used on a Centerlock bike or vice versa. These converters usually attach to the bike hub in the same manner as the intended rotor and the new rotor simply attaches to the converter.

Uses

• Due to the fact that Centerlock rotors are not readily available, they are not for everyone. Six-bolt rotors are appropriate for people who wish to regularly ride their bikes or to use them for simple exercise, tricks or training. Centerlock rotors are more appropriate for people who wish to race their bikes or use them for high energy or heavy use. A Centerlock rotor will allow a bike to go faster and to stop more quickly, while a 6-bolt rotor is easier to find.
