At Redchilli Bikes, we believe a track bike should be built around the rider, the discipline and the way the bike will actually be used on the boards. Track cycling leaves very little room for compromise. Position, gearing, crank length, cockpit, wheels and chainline all influence how confidently and efficiently the rider can hold speed, change line and produce power. That is why we look beyond the frame alone and consider the complete bike as one connected system.
Because on the track, simplicity does not mean fewer decisions. It means every decision matters more.
The line through a velodrome corner is decided long before you reach the banking. It begins with position: where your weight sits between the wheels, how freely you can turn the gear, and whether the bike stays composed when the pace rises. A custom track bike build is not simply a striking frame with premium parts. It is a fixed-gear machine specified around the way you produce power, hold speed and ride the track.
That distinction matters. Track cycling is unusually uncompromising. There are no gears to hide an unsuitable ratio, no freewheel to soften an unbalanced position and very little room for a component choice that feels merely acceptable. The right build should feel direct and purposeful, but never nervous or restrictive. On a fixed-gear bike, that balance is especially important because every input from the rider is transmitted immediately through the machine.
Start with the rider and the discipline
‘Track bike’ covers a broad range of demands. A rider preparing for bunch races needs a bike that changes line cleanly, accelerates repeatedly and remains manageable among other riders. A sprinter may prioritise stiffness, clearance and a position that supports maximum force. For pursuit, endurance events or regular club sessions, sustainable aerodynamics and a smooth, efficient pedal stroke often matter more than outright rigidity.
The same frame and wheel combination will not suit each of those riders equally. That is why the intended discipline should influence the build from the outset rather than being treated as something to adapt later. Before choosing components, establish the purpose of the bike, the tracks you ride and the events that matter most. A compact indoor velodrome, an outdoor concrete track and a steep banking can each change the practical brief. So can your experience. A newer track rider may benefit from a more accessible position and predictable handling, while an experienced racer may know precisely where they want greater front-end support or a more aggressive reach.
It also depends on whether the bike must meet a specific governing body’s regulations. Race rules can affect frame dimensions, wheel depth, handlebar shape and extensions. These details should be resolved at the start, not discovered after a carefully chosen build is complete.
Fit comes before the frame size
A stock size chart is a useful reference point, not a finished fitting process. On the track, small changes in saddle setback, bar drop, crank length and cockpit reach are felt immediately. With no coasting, your position has to work throughout every pedal revolution, whether you are winding up for a flying effort or controlling cadence high on the banking.
A proper fit considers more than flexibility. We look at hip stability, ankle movement, shoulder comfort, preferred cadence and the way you generate force. The goal is to create a position that is compact enough to be efficient in clean air, open enough to breathe and produce power, and stable enough to hold under pressure. The fastest position is ultimately the one the rider can repeat consistently as cadence, speed and fatigue change through the session.
Crank length deserves particular attention. Shorter cranks can improve clearance and reduce the peak hip angle, which may help riders who work at high cadence or use a lower, more aerodynamic position. Longer cranks can provide a more familiar leverage feel for some riders, particularly those moving from road riding. Neither is automatically faster. The correct choice is the one that complements your proportions, event demands and pedalling style.
Frame geometry then provides the platform for that position. Reach, stack, fork offset, trail and rear-centre length all influence how the bike behaves. A responsive track frame should be accurate when you change direction, yet calm enough that you can ride a straight line at speed without fighting the front wheel. The intended rider position must be achievable without a stack of compromises in stem angle, spacer height or extreme saddle adjustment.
Building a custom track bike around feel
Carbon track frames can be exceptionally light and stiff, but stiffness alone is not a design brief. Excessive harshness can make a bike feel unsettled over imperfect outdoor surfaces and can leave the rider fatigued during longer sessions. Equally, a frame that lacks torsional support can feel vague when you commit to a move or apply force out of the saddle.
The most useful question is not, ‘What is the stiffest frame?’ It is, ‘What does this rider need the bike to do?’ A powerful sprinter, an endurance racer and a rider developing track skills may arrive at different answers. At Redchilli Bikes, the build is considered as a complete system: frame, wheels, contact points, drivetrain and fit working together rather than as a collection of headline specifications. That approach is particularly important on the track, where relatively small changes in stiffness, position or gearing can noticeably alter how connected the bike feels beneath the rider.
The frame must also be compatible with the practical elements of the build. Check the bottom bracket standard, axle format, chain tension arrangement, tyre clearance and permitted wheel dimensions before committing to components. Track equipment is often beautifully simple, but that simplicity makes compatibility non-negotiable.
Wheel choice is about more than depth
Track wheels need to transfer effort cleanly, hold their line and suit the events being ridden. Deep-section carbon wheels can offer aerodynamic benefit at speed, especially in timed events, but a shallower option may be more practical for regular training, bunch racing or changing conditions at outdoor venues.
Rim width and tyre selection should be chosen together. A properly matched tyre can improve confidence and rolling feel without adding unnecessary drag. Tubular, tubeless and clincher systems each have merits, although venue rules and frame clearance may narrow the choice. For many racers, the right answer is a reliable training wheelset and a separate race set chosen for the event. The important point is that the wheel choice should complement the rider and discipline rather than simply chase the deepest possible rim.
Hubs and bearings matter too, but not in the way marketing often suggests. Reliability, axle security and accurate chainline are more valuable than chasing marginal claims. On a fixed-gear bike, a secure threaded cog and lockring, fitted correctly and inspected regularly, are fundamental safety items.
Drivetrain precision earns speed
A track drivetrain has fewer parts than a road drivetrain, which makes each decision more visible. Chainline should be straight and exact. Misalignment increases wear, wastes energy and can create noise or an unpleasant sensation under load. The chainring, bottom bracket axle or chainset, rear cog and hub spacing must be selected as one system.
Gear choice should reflect the rider, not the fashion of the moment. A bigger gear can look decisive on paper, but it is only useful if you can accelerate it and sustain it at the required cadence. Conversely, an easier gear may allow quicker jumps and better control in a tactical race. Most committed riders benefit from owning a sensible range of sprockets and testing ratios in training, with cadence data and honest feel informing the final choice.
Chainring size can also affect practical gearing steps. A larger ring paired with a proportionally larger sprocket may offer finer adjustment between ratios, but it must suit the frame’s clearance and the rider’s needs. The important outcome is repeatable, efficient power delivery, not a drivetrain built around numbers alone. On a track bike, precision is performance. A quiet, correctly aligned drivetrain allows the rider to concentrate on cadence, position and the line ahead.
Cockpit and contact points shape control
Bars are not an accessory on a track bike. Their shape determines leverage in the turns, shoulder width, wrist comfort and how naturally you can move around the bike. Traditional track drops remain a strong choice for many disciplines, while pursuit bars and extensions have a clear role in timed events where regulations permit them.
Bar width should support breathing and control. Very narrow bars can reduce frontal area, but may compromise stability or comfort, especially for riders still refining their track handling. Stem length and angle should finish the fitted position rather than force it. The saddle deserves the same careful approach: its shape, width and rail adjustment determine whether you can hold a stable pelvis when the effort becomes demanding.
Pedals, shoes and cleats complete the connection. Secure retention and consistent cleat placement matter because a fixed gear asks the rider to control both the driving and resisting phases of the pedal stroke. A minor alignment issue that is tolerable on a café ride can become a real limitation during repeated track efforts.
Leave room to develop
The best custom track bike build is not necessarily frozen on the day it leaves the workshop. Riders get fitter, become more confident on the banking and often find that their strongest discipline is not the one they expected. A thoughtful build leaves sensible scope to alter gearing, bar position, wheel choice and contact points without undoing the foundations.
That is why the conversation after delivery matters. Use the bike, make notes after hard sessions and pay attention to the moments when it feels especially composed or slightly constrained. A tailored track bike should encourage commitment, not demand that you adapt yourself to it. When fit, specification and purpose are aligned, the bike becomes quiet beneath you – precise through the turn, ready when the pace changes, and entirely your own.
Built for the line. Built around the rider
A track bike may be mechanically simple, but building the right one is anything but. Position, gearing, crank length, cockpit, wheels and drivetrain alignment all need to work together so the rider can accelerate cleanly, hold speed efficiently and remain composed when the pace rises.
At Redchilli Bikes, that means starting with the rider and the discipline rather than a fixed specification. Because the best track bike should not ask you to adapt around it. It should disappear beneath you when the banking, cadence and timing demand your full attention.
Built around you. Built for the boards. Your Bike. Your Way.
