Suspension Types

Different types of mountain bikes

Mountain bike suspension systems are designed to absorb impact from rough terrain, enhancing control and comfort.

These systems are categorized into three main types, each with distinct characteristics.

Rigid


Rigid mountain bikes do not feature any suspension.

They are typically lighter and less expensive due to their simplicity.

These bikes suit cyclists seeking a direct and responsive ride on less technical terrain.

Hardtail


A hardtail mountain bike has a suspension fork at the front but no rear suspension.

This setup offers a compromise between efficiency and comfort.

It allows for better power transfer to the pedals and improved front-wheel traction on uneven ground.

The absence of rear suspension makes the bike lighter and more suitable for cross-country riding.

Full Suspension


Full-suspension mountain bikes are equipped with both front and rear suspension systems.

They offer the most comfort and traction, especially on challenging trails.

These bikes can absorb significant bumps and shocks, thus reducing fatigue and allowing for more aggressive riding.

However, they are typically heavier and more expensive than their rigid, hardtail counterparts.

Wheel Sizes

Different types of mountain bikes

Wheel size significantly influences a mountain bike’s handling, traction, and ability to roll over obstacles.

Each size offers distinct advantages tailored to different terrains and styles of riding.

26 Inch Wheels


Originally the standard for mountain bikes, 26-inch wheels are known for their lighter weight and nimble handling.

These wheels accelerate quickly and offer increased maneuverability in tight turns and technical sections.

27.5 Inch Wheels


27.5-inch wheels, or 650b, balance agility and obstacle clearance.

They provide a middle ground, offering better traction and smoother rollover capabilities than 26-inch wheels while maintaining responsive handling.

29 Inch Wheels


29-inch wheels are favored for their ability to traverse rough terrain smoothly and maintain speed over obstacles.

They offer superior traction due to a larger contact patch with the ground.

However, it may feel less agile to some riders due to the increased wheel size.

Mixed Size Wheels


For mixed-size wheels or a mullet setup, use a 29-inch wheel in the front and a 27.5-inch wheel in the rear.

This combination takes advantage of the rollover benefits of a larger wheel up front.

While retaining the playfulness and stronger acceleration of a smaller wheel at the back.

Braking Systems

Mountain bikes have one of two main braking systems to ensure rider safety through effective speed control and stopping power.

Rim Brakes


Rim brakes employ brake pads that grip onto the rims of the wheels.

They are typically lighter than disc brakes and are easier to inspect for wear and tear.

They operate by the brake lever pulling a cable that causes two brake pads to clamp onto the rim, creating friction that slows the bike down.

Rim brakes are generally less expensive and simpler to maintain.

AdvantagesDisadvantages
Lighter weightLess effective in wet or muddy conditions
Easy to inspect and maintainCan wear out the rim over time
Usually more affordableNot as powerful as disc brakes

Disc Brakes


Disc brakes feature brake pads that grip onto a rotor mounted to the wheel hub.

They provide more consistent braking in all weather conditions and are more effective at dissipating heat.

Disc brakes can be hydraulic or mechanical.

Hydraulic disc brakes offer more progressive and stronger braking with less effort.

Whereas mechanical disc brakes use a cable and are typically easier to service.

AdvantagesDisadvantages
Superior stopping powerUsually heavier than rim brakes
More consistent in adverse weatherMore complex, can be harder to service
Less wear on the wheel rimTypically more expensive than rim brakes

Both systems require regular maintenance to ensure optimal performance.

Their choice often depends on the rider’s preference, riding conditions, and budget.

Gearing Configurations

Gearing configurations on mountain bikes greatly impact performance characteristics, offering versatility or simplicity depending on the system.

They also influence speed, control, and efficiency on various terrains.

Single-Speed


Single-speed mountain bikes epitomize simplicity in gearing.

They have a one-gear ratio without the need for gear-shift mechanisms.

Riders appreciate their lightweight design and reduced maintenance.

This makes them ideal for those who value straightforward mechanics and the challenge of using one gear for all terrains.

Multi-Gear Systems


Multi-gear systems, on the other hand, provide a range of gear ratios.

These configurations typically involve front and rear derailleurs, shifters, and cassettes.

Riders lean on multi-gear systems for their flexibility, as they allow quick adjustments to the gear ratio to match the riding conditions.

This segmentation makes climbing steep hills more manageable and enables higher speeds on flat or descending trails.

  • Common configurations include:
    • 2x systems with two chainrings at the front
    • 3x systems with three chainrings
    • 1x systems, or “one-by,” use a single front chainring combined with a wide-ranging cassette to provide a similar breadth of gears as 2x or 3x systems but with less complexity.

Mountain Bike Fit and Sizing

Frame Size:
The frame is the core of a mountain bike’s fit.

Manufacturers usually list frame sizes in inches, corresponding to the seat tube length.

Riders must select a frame size compatible with their height for optimal comfort and performance.

Recommended frame sizes are typically categorized by rider height:

  • Small: for riders 5’4″ to 5’7″
  • Medium: for riders 5’7″ to 5’10”
  • Large: for riders 5’10” to 6’1″

Leg Inseam and Standover Height:
Standover height is crucial for safety and confidence.

There should be about two inches of clearance between the rider and the top tube when standing flat-footed over the bike.

Leg inseam measurements help determine the correct standover height.

Adjusting the Saddle:
Saddle height affects pedaling efficiency and comfort.

A properly adjusted saddle allows the leg to be almost completely straight when the pedal is at the lowest point with the rider’s foot flat.

  • Height: Adjust vertically for full leg extension.
  • Angle: Keep it neutral to prevent sliding forward or backward.
  • Fore/Aft Position: Ensure the knee is over the pedal axle for optimal power.

Handlebar Reach and Height:
Handlebar position impacts handling and comfort.

Achieve the correct reach by adjusting the stem length and angle.

They should maintain a straight, neutral back with slight bends in the elbows.

  • Reach: Adjust for arm length; fingertips should comfortably grip the handlebars.
  • Height: Line it with saddle height or slightly lower for aggressive riding styles.

Riders should refine the fit with professional help to account for individual body proportions and riding preferences.
