From London Streets to Steep ascents: How Simon Warren Reimagined a Fixie for Hill Climb Racing
Table of Contents
A London fixed-gear bicycle, once a symbol of urban cycling, has been reborn as a dedicated hill climb racer thanks to Simon Warren, Britain’s number one hill climb expert. Warren’s project demonstrates that performance isn’t always about the latest technology, but rather a thoughtful build focused on simplicity and functionality. The conversion, completed in October 2025, showcases a unique approach to competitive cycling, blending classic aesthetics with a modern racing spirit.
Warren’s inspiration stemmed from a desire to revisit the roots of hill climbing, a discipline historically defined by stripped-down bikes and raw power. He sourced a Monoc frame – a model with a storied past – and embarked on a build that prioritized weight reduction and direct responsiveness. The result is a machine perfectly tailored for tackling the UK’s most punishing inclines, including the infamous Bank Road.
The build features a Reynolds Onzo fork, which Warren describes as still the most stunning fork I have ever owned
. This is paired with an Easton EA50 stem,cut-down Easton EA70 bars,and Campagnolo Chorus levers,modified for comfort. A Token Accura CNC brake,USE seatpost,and a drilled Selle Italia Flite TT saddle complete the setup.
Despite the focus on minimalism,Warren acknowledges the bike isn’t exceptionally light,tipping the scales at 5.98kg. However, he emphasizes the project’s value lay in the process of assembly and the enjoyment derived from riding a uniquely crafted machine.
| Component | Manufacturer |
|---|---|
| Frame | Monoc |
| Fork | Reynolds Onzo |
| Stem | Easton EA50 |
| Bars | Easton EA70 |
| Levers | Campagnolo chorus |
| Brake | Token Accura CNC |
| Seatpost | USE |
| Saddle | Selle Italia Flite TT |
| Weight | 5.98kg |
Warren’s Monoc represents a departure from the trend of highly specialized, expensive race bikes. It’s a testament to the enduring appeal of fixed-gear simplicity and the satisfaction of building a bike tailored to a specific purpose.
Did You Know?
Hill climbing competitions frequently enough prioritize rider strength and technique over equipment, making a well-built, lightweight bike like Warren’s a formidable weapon.
From its origins on London’s streets to its new life conquering the UK’s toughest climbs, Warren’s project demonstrates that even seasoned professionals find joy in the process of creation and the challenge of pushing the boundaries of cycling.
Pro Tip:
Fixed-gear bikes require a high degree of skill and control, as riders rely solely on leg power and momentum to navigate descents and maintain speed.

The Enduring Appeal of Fixed-Gear Cycling
Fixed-gear cycling, frequently enough associated with urban culture, has a long history rooted in track racing and practicality.The simplicity of a single gear and direct connection between pedals and wheel offers a unique riding experience, fostering a strong sense of control and efficiency. While not ideal for all terrains, fixed-gear bikes have gained popularity among commuters and enthusiasts seeking a minimalist and engaging cycling experience. The trend towards stripped-down builds, as exemplified by Simon Warren’s project, reflects a broader movement within cycling that values craftsmanship, functionality, and a connection to the sport’s heritage.
Frequently asked Questions about Fixed-Gear Hill Climbing
- What is a fixed-gear bike? A fixed-gear bike has a drivetrain where the cog is directly connected to the wheel, meaning the pedals always move when the wheel moves.
- Why would someone use a fixed-gear bike for hill climbing? The direct connection provides efficient power transfer and a unique riding feel, appealing to riders who prioritize control and simplicity.
- Is a fixed-gear bike suitable for all hill climbs? Steeper,more technical climbs benefit from the control offered by a fixed-gear,but longer,less steep climbs might potentially be more efficiently tackled with gears.
- What are the advantages of a lightweight bike for hill climbing? Reducing weight minimizes the energy required to overcome gravity, making ascents easier and faster.
- How critically important is bike maintenance for a fixed-gear? Regular maintenance, notably chain tension and brake adjustment, is crucial for safe and efficient riding.
