Fatigue Reduction: You will feel less tired on long downhill rides. The suspension handles most of the bumps.
Tuning Options: You can change the suspension to fit your weight. It can also match the type of terrain you ride.
With these benefits, many riders choose a bike frame dual suspension for their adventures.
Applications of Full Suspension Bikes
Full suspension bikes are great for many cycling types. Here are some popular uses:
Downhill (DH): This type focuses on fast descents and tricky terrain. Bikes here need a lot of suspension travel to handle impacts well.
eMTB (Electric Mountain Bike): These bikes are good for climbing and longer rides. They work well in many mountain biking situations.
DESIGN CONSIDERATIONS FOR BIKE FRAME DUAL SUSPENSION
When you build a bike frame with dual suspension, you need to think about some design choices. These choices can change how well your bike works, how comfortable it is, and how good your ride feels. Let’s look at the main areas to focus on: geometry, material choices, and types of suspension linkage.
Geometry and Handling
The shape of your bike frame is very important. It affects how the bike rides on different surfaces. Here are some key geometric factors to think about:
Geometric Factor | Description |
|---|---|
Head Angle | Affects how well a bike climbs or goes down hills; changes weight balance during climbs and descents. |
Seat Tube Angle | Influences where the rider’s weight sits compared to the bike’s axles, affecting handling on slopes. |
Reach | Important for bike fit; shows the distance between saddle and handlebars, affecting comfort and control. |
Stack | Affects handlebar height choice, which impacts riding position and comfort. |
Knowing these factors helps you build a bike that feels right for your style. Good geometry can improve your control and stability, especially on tough trails.
Material Choices
Picking the right materials for your bike frame is very important. Different materials have different strengths and weaknesses that can change your ride. Here’s a quick look:
Material | Advantages | Disadvantages |
|---|---|---|
Steel | Strong, durable, cheap, helps with suspension | Heavy, can rust |
Aluminum | Light, stiff, cheap, good strength-to-weight ratio | Not as durable, can feel rough on rides |
Carbon Fiber | Lightest, stiffest, great for speed | Can have durability problems, varies in quality and price |
Titanium | Very light, strong, great for suspension, lasts long | Expensive, hard to work with, tough to repair |
When choosing materials, think about how they affect the bike’s weight and strength. For example, aluminum is light and affordable, but it can wear out. Carbon fiber is very stiff and light, making it great for high-performance bikes.
Suspension Linkage Types
The kind of suspension linkage you pick can change how your bike absorbs shocks and how it rides. Here are some common suspension systems:
Suspension System | Characteristics | Pros | Cons | Examples |
|---|---|---|---|---|
VVP | Links that turn in opposite directions | Very adjustable for different needs | More complex and tighter fit | Santa Cruz Hightower, Pivot Trail 429 |
DW-Link / Maestro | Links that turn in the same direction | Adjustable for sensitivity and predictability | Might not pedal as efficiently | Devinci Troy, Trek Fuel EX |
High-Pivot Idler | Idler pulley near the main pivot | Better at absorbing impacts | More complex and can create drag | Forbidden Druid, Cannondale Jekyll |
Split Pivot / ABP | Pivot located directly on the rear axle | Braking does not affect performance | Might not pedal as efficiently | Orbea Rallon |
Horst Link / 4-Bar | Pivot on the chainstay, just in front of the rear axle | Very adjustable and predictable | Can affect anti-squat and pedal kickback | Specialized Stumpjumper EVO, Canyon Strive |
Different linkage designs change how your bike handles shocks and reacts to the ground. For example, a higher leverage ratio may need stiffer springs, which can affect your tuning choices and overall ride quality.
By carefully thinking about these design parts, you can build a dual suspension bike that fits your needs and makes your ride better.
