Hope Pro 5 Hub Buyers Guide

The Hope Pro 5 is one of the most versatile and high-performance hub ranges available. Designed for durability, easy servicing, and broad compatibility, it’s built to meet the needs of everyone from endurance riders to downhill racers.

Because there are many hub options — including axle types, freehub bodies, spoke interfaces, and brake mounts — it’s important to select the correct configuration for your frame, fork, and drivetrain. This guide explains everything you need to measure and identify before you buy.

1. Axle & Hub Spacing – Measuring Your Frame and Fork

Your hub must match your frame and fork spacing.

Rear Hub

1. Remove your rear wheel.
2. Measure the internal width between the frame dropouts (where the hub fits).
3. Common sizes:

• 135 mm QR (Quick Release): Older MTB and road bikes.
• 142 mm x 12 mm thru-axle: Most modern MTBs and gravel bikes.
• 148 mm x 12 mm Boost: Current MTB standard.
• 150 mm / 157 mm x 12 mm: Downhill or Super Boost frames.
• 130 mm QR: Traditional road bikes.

Note the axle type (QR skewer or thru-axle, and its diameter).

Front Hub

1. Remove your front wheel and measure between the fork dropouts.
2. Common sizes:

• 100 mm QR: Older bikes.
• 100 mm x 12 mm / 15 mm: Common on road and MTB thru-axle setups.
• 110 mm x 15 mm Boost: Modern MTB standard.
• 110 mm x 20 mm: Downhill or older forks.

Hope Pro 5 hubs are available in all common configurations, and end caps or conversion kits can adapt many setups if you change bikes later.

 

2. Brake Mount Type – IS or Centerlock

Hope hubs come with either:

• 6-Bolt (ISO) Mount: Six small bolts secure the rotor. Common on most MTBs and Hope’s own rotors.
• Centerlock Mount: A splined interface with a lockring. Common on Shimano setups.

Check your existing rotors:

• If you see six small bolts around the disc, you need 6-Bolt.
• If you see a single toothed ring with a lockring, you need Centerlock.

 

3. Freehub / Driver Type – Matching Your Cassette

The freehub body (or driver) determines which cassette fits your rear hub.
Hope Pro 5 hubs can be fitted with different freehub bodies.

 

Tip: Check your cassette’s spline shape — it will indicate which driver type you need.

4. Spoke Type – J-Bend or Straight-Pull

Hope offers Pro 5 hubs in two flange styles:

• J-Bend: Traditional 90-degree bend spokes.
• Easier to source and replace.
• Compatible with most wheel builders.
• Straight-Pull: Spokes enter the hub straight, for slightly higher stiffness and more even tension.
• Often used on high-end, performance wheels.

If you’re rebuilding an existing wheel, match your old hub’s spoke type to reuse spokes (if lengths are compatible).

5. Spoke Count – Balancing Strength and Weight

The number of spoke holes in your hub must match your rim.

 

Check your rim’s drill pattern before ordering — mismatched counts cannot be built.

6. Checklist Before Ordering

1. Measure axle width and type (front and rear).
2. Identify brake mount (6-Bolt or Centerlock).
3. Confirm freehub / driver type for your cassette.
4. Choose J-Bend or Straight-Pull spokes.
5. Match spoke hole count to your rim.

Having these five details ensures a perfect fit for your bike.
