Mountain Bike Hubs Core features：

1. Perlin configuration (front 2 rear 5)
   ◦ Front 2-plywood: improves front wheel rotation efficiency, reduces friction, suitable for high speed riding.
   ◦ Rear 5-pin: strengthen the drive side support, share the pedaling load, and enhance durability (commonly found in high-end hubs).
   ◦ Sealed design: dustproof and waterproof, adapting to harsh environments such as mountain cross-country, reducing maintenance frequency.
2. 120 Rattles High Density Ratchet
   ◦ Fast Bite: 120 ratchet teeth (3° bite angle) for near “zero delay” pedal response, suitable for technical climbing or acceleration.
   ◦ High-density design: more refined power than traditional 72/90 rattle hubs, but may sacrifice a little quietness (some models add grease for noise reduction).
3. Smooth No-Holds-Barred Technology
   ◦ Precision-machined core: reduces rotational resistance, with low-friction perlage (e.g. ABEC-5 or ceramic perlage).
   ◦ Ratchet material: typically steel or titanium, combining durability with light weight.
   
   Applicable Scenarios

• Off-road/Enduro: high Perlin count + sealing for complex terrain.
• Race XC: 120 rattles for quick response to improve sprinting efficiency.
• Long distance riding: low maintenance design for multi-day rides.
  
  Suggestions for selection

1. Compatibility: Confirm hub openings (front 100mm/rear 142mm, etc.), tower base specifications (Shimano/SRAM/XDR).
2. Brand reference: similar technology can be found in high-end hubs such as DT Swiss 350, Hope Pro 4, etc. Domestic products such as Novatec also have cost-effective models.
3. Maintenance Tips: Regularly check the Perrin seals, and recommend replenishing the ratchet area with special grease every six months.

Mountain Bike Wheel Hubs FAQ
1: When ordering mountain bike hubs, how do I make sure the quality of the material meets the high performance requirements?
When ordering, it is critical to choose high quality materials, such as aluminum alloy or carbon fiber. Aluminum alloy is lightweight, strong and corrosion-resistant; carbon fiber is lighter and can increase speed and agility. Check the source of the material, quality certification, and understand the processing technology, such as whether the aluminum alloy has been specially treated, and whether the carbon fiber resin and weaving process is of high quality, to ensure that the material meets the high-performance requirements of mountain bike parts.
Question 2: How to optimize the hub of a custom mountain bike wheel to maintain stability in different mountain conditions?
Customized hubs should focus on structural design. On the one hand, the hub shell should be reinforced to withstand impact without deformation; on the other hand, equipped with shock absorbing cushioning structure, such as built-in shock springs or rubber blocks, to reduce the impact of bumps. Reasonable design geometry ensures wheel balance and improves riding stability.
Q3: What are the precautions for installing hubs on customized mountain bike wheels?
When installing a customized wheel hub, make sure that the hub fits the frame and check the position of the mounting holes and the spacing between them. Install the bearings correctly, pay attention to the direction and torque, avoid too tight or too loose. Check the rotation of the wheel after installation to make sure it is smooth and without any jamming or rattling, which is important for the normal use of mountain bike parts.
4: Will there be compatibility problems when adapting different brands of mountain bike wheel hubs to other accessories?
There may be. Due to differences in hub journal design, spoke pitch, or brake mounting interface, they may not be compatible with some accessories. Before ordering, you should understand its compatibility with other accessories, refer to the manual or consult us, test if necessary, and choose a product with strong universality to ensure that the mountain bike accessories work together.
5: Can the customized mountain bike wheel hubs be adjusted for personalized shifting function?
This is possible with some high-end customized wheel hubs. They are equipped with an adjustable shifting system, which can adjust the gear ratio and shift effort according to riding habits and road conditions.
Question 6: How can customized mountain bike wheel hubs improve the handling of different types of mountain riding?
Custom hubs can improve handling in a number of ways. For off-road riding, wider hubs are designed to increase contact area and improve stability and grip; for downhill riding, focus on heat dissipation performance and brake adaptability, and use lightweight design to reduce weight and improve flexibility to meet the needs of different riding scenarios.
7: What special maintenance measures are required for customized mountain bike wheel hubs after daily riding?
After daily riding, the hubs should be cleaned regularly to remove impurities, using special cleaners and soft cloths. Regularly check the bearing lubrication, check, replenish or replace the grease every certain mileage (e.g. 1000 – 2000 kilometers). Also check if the hub bolts are loose and tighten them in time.
8: How does improper maintenance of mountain bike wheel hubs affect the overall performance of a mountain bike?
Improper maintenance can affect the overall performance. Accumulation of impurities increases friction and makes the wheel rotate poorly; poor lubrication of the bearings increases friction and accelerates wear and tear, shortening life and even leading to malfunction; loose bolts cause the hub to shift, affecting the balance of the wheel and maneuverability, so it is important to maintain them correctly on a regular basis.
Price and cost-effective category
9: What are the main factors for the price of customized MTB hubs? How to judge the price/performance ratio?
The price depends on the material, design and craftsmanship, brand and other factors. High-end materials such as carbon fiber have high price, special design and craftsmanship will increase the cost, and famous brands have high price due to quality and service guarantee. To judge the cost-effectiveness depends on the comprehensive consideration of price and performance, quality and function, compare different products and choose the high quality and reasonable price.
