Custom Build Breakdown: A Real GUST Bike Upgrade Example
To demonstrate how flexible the GUST bike customisation platform really is, this GUST mountain bike was upgraded using well-known, high-quality aftermarket components. Every modification was possible because the bike is built around universal sizing and standard interfaces, allowing seamless upgrades without compromises.
This is not a concept build — it is a real-world example of how a stock GUST bike can evolve into a refined custom mountain bike.
Braking System Upgrade: Hope Hydraulic Disc Brakes
The original mechanical braking system was replaced with Hope hydraulic disc brakes, delivering a noticeable improvement in braking performance.
The upgrade provides:
- Stronger and more consistent stopping power
- Improved modulation and control
- Reliable performance in wet and muddy conditions
This single change significantly improves trail confidence and overall ride safety.
Suspension Upgrade: Custom Short Marzocchi Forks
The front suspension was upgraded to custom short-travel Marzocchi forks, enhancing front-end control and ride quality.
Key benefits include:
- Improved damping and shock absorption
- Better handling on uneven terrain
- A more responsive, trail-focused riding feel
Thanks to standard steerer and headset dimensions, the fork upgrade required no special adapters or frame modifications.
Drivetrain Conversion: SRAM X9 with FSA 1x Crankset
The drivetrain was converted to a modern 1x setup, using:
- FSA 1x cranks for durability and simplicity
- SRAM X9 rear derailleur for precise, dependable shifting
This configuration reduces weight, removes the front derailleur, and improves chain stability — ideal for trail riding and mixed terrain use.
Tyre Upgrade: DMR All-Terrain Tyres
The bike now runs DMR all-terrain tyres, selected for their balance of grip and durability.
These tyres offer:
- Strong traction on dirt, gravel, and urban surfaces
- Predictable cornering characteristics
- Long-lasting performance for everyday riding
Standard rim sizing allowed a direct fit with no clearance issues.
Cockpit and Contact Point Improvements
To fine-tune handling and rider comfort, additional upgrades were made:
- Short stem for quicker, more responsive steering
- SDG saddle for improved comfort and durability
These changes enhance control and reduce fatigue during longer rides.
Why This Custom Build Works on a GUST Frame
This custom build is not an exception — it reflects exactly what the GUST mountain bike platform is designed to support.
The frame accepts:
- Industry-standard brake mounts
- Standard steerer and fork dimensions
- Universal crank, bottom bracket, and drivetrain compatibility
- Standard cockpit and seatpost sizing
There are no proprietary systems, no locked components, and no limitations that restrict future upgrades.
From Stock Bike to Long-Term Custom Platform
This example shows how a GUST 24-inch mountain bike can evolve from a reliable stock bike into a serious custom build, using components typically found on much higher-priced bikes.
It clearly demonstrates that:
- GUST bikes are built for long-term use
- Upgrades are practical and worthwhile
- Customisation adds real value over time
Why Riders Choose GUST Bikes from Black Bike
GUST bikes from Black Bike are built as proper upgrade-ready platforms, not disposable products. Riders benefit from a solid frame, universal standards, and the freedom to customise their bike as their needs change.
With UK assembly, £9.99 fast UK delivery, a 30-day money-back guarantee, and a 2-year warranty, buying a GUST bike is a confident, low-risk decision.
These bikes are chosen by:
- Riders who want a bike that lasts beyond one season
- Parents buying once for growing riders
- Commuters and trail riders who value serviceability
- Anyone who wants the freedom to upgrade without restrictions
You can ride a GUST bike exactly as it comes — or turn it into something exceptional over time.
This is exactly what I wanted to know before buying. I love the idea of starting with a solid base frame and upgrading over time rather than buying a cheap bike that you eventually throw away. The Hope brake upgrade in particular makes a real difference — I upgraded my brakes on my mountain bike last year and the improvement in wet conditions was night and day. Good to know the GUST frames are built to accept standard components without faffing around.
This is exactly the kind of content I was looking for. I tinker with bikes as a hobby and the fact that the GUST uses completely standard interfaces means I could actually work on it myself without needing any special tools or workarounds. The SRAM X9 drivetrain swap is a great upgrade path too — solid components that last. Nice to see a budget bike brand that doesn’t lock you in.
