What more could you want from a disc brake hub set?
Disc Brake hubs are fun! They take us on adventures, away from the hustle of our everyday lives, away from traffic, sometimes way into the unknown. When designing a great disc brake hub set, there are a few things on everybody's mind. Weight, stiffness, and smooth rolling bearings are things we have all come to just expect from our hubs. However, on a set that is going to be used in the middle of a gravel road mecca, miles from cell phone coverage, and sometimes with nobody around for hours. . . strength and durability take a precedence. With the design of the new Quest hubs, we have touched on all this and more to give every possible advantage and confidence in your wheelset.
The Centerlock mount is simply a much better way to mount disc brake rotors. You don't have to tighten down 6 individual bolts to a specific torque setting. This makes swapping rotors super quick and easy, and ensures the rotor is perfectly mounted every time. If you have a current favorite 6 bolt rotor, you can easily run a centerlock to 6 bolt adapter and still run your favorite rotors. The Centerlock design also helps for weight savings, and provides a cleaner look.
When you are riding technical trails, cross racing, or starting a sprint after jumping out of a corner, the faster you can start to pedal again the more of an advantage you will have. This especially holds true on the mountain bike trails, going over technical sections where you may need to stop and start pedaling multiple times in a matter of a few feet. Having your hub engage extremely quick can be the difference between making it through that rock garden or having to put a foot down and walk (promptly getting laughed at by all your friends).
With the Quest hubs we have 6 pawls operating in a 3X3 manner on 36 engagement teeth. This results in a super-quick 5 degrees of engagement. Now your hubs can have a quicker engagement than a reality TV star!
Multiple Axle Configurations
It's no big secret that the past few years have been dominated by a whole slew of axle "standards". Up until a few years ago, every bike had quick release front and rear. However with disc brakes we went from having a few millimeters of adjustment between rim and brake pads to a couple tenths of a millimeter between rotor and disc brake. Wheels need to be lined up perfectly, or you will have brake rub. With the thru axle, the wheel is always centered so you never have to worry about if your wheel is in the dropout just right or not.
It should have been that simple. . . but this is the bike industry, and nothing is ever that simple. Instead of just having one thru axle size for front and rear, we now have to know what size axle our bikes take and match the hub up to that. Fortunately for you, the Quest hubs feature a super easy to convert end cap system where you can run the hubs on any axle standard they can dream up.
Available axle configurations are
100X12mm thru axle
100X15mm thru axle
135X12mm thru axle
142X12mm thru axle
Shimano, Campy, and XDR Driver compatible
Easily swap freehub bodies as simple as swapping end caps. You can choose Shimano, Campy, or the Sram XDR Drivers (12 speed road). Note that the Sram XDR driver is only compatible with Sram cassettes meant for XDR drivers. If the Sram cassette is not an XDR driver cassette, you will need the Shimano freehub body.
Front hub weight - 120 grams
Front hub spoke counts - 24 and 28
Rear hub weight - 245 grams
Rear hub spoke counts - 28 and 32
Swappable end caps for any axle configuration
Separate Boost and Standard Sized Hubs for optimized geometry
5 degree engagement
36 teeth - 6 pawls, engaging 3X3
Extremely easy to service
Bearing sizes are often overlooked when looking at the performance of the hubs. Smaller bearings will save weight, but can come at the expense of a lower static load and decreased durability. We studied the loads of different sized bearings and in the end the increase of 5 grams per bearing was more than worth it for years of durability and increased stiffness of the wheels.
Bearing sizes are as follows
Front hub – 2X 6902
Rear hub – 2X 6902 in the hub shell; 2X MR15267 in the freehub body
