At Redchilli Bikes, David chooses the handlebar as part of each individual build.
The conversation often starts with your current bike. Where do your hands naturally settle? Do you use the drops on long descents, or do they feel too low or too far away? Those answers help shape the choice of bar, stem and lever position before your bike is hand assembled in Devon.
A handlebar can look like a small detail beside a carbon frame and a carefully chosen wheelset, yet it has a direct effect on how a bike feels from the first mile. Understanding handlebar reach and drop helps explain why one cockpit feels natural while another leaves you stretched on the hoods or reluctant to use the drops. It is about understanding where your hands sit, how easily you can change position, and whether the front of the bike supports the way you actually ride.
For a rider buying a new road, endurance or gravel bike, handlebar dimensions deserve the same consideration as frame size, stem length and saddle position. The right bar can make an otherwise good fit feel natural. The wrong one can leave a rider overextended, cramped, reluctant to use the drops, or unable to settle into a consistent position.
What handlebar reach and drop mean
Handlebar reach is the horizontal distance from the centre of the top section of the bar to the furthest forward point of the drops. Reach and drop describe the shape of the bare bar. Where your hands actually sit also depends on the bend, bar rotation and where the brake hoods are fitted.
Handlebar drop is the vertical distance from the top of the bar to the lowest point of the drops. It indicates how much lower your hands sit when you move from the tops or hoods into the drops.
These measurements are usually given in millimetres. A compact road bar might have a reach of around 70-80mm and a drop of 120-130mm. A traditional road bar may have a longer reach and deeper drop, while gravel bars often use a short reach and a shallow drop, sometimes with flared lower sections for more control off-road.
The numbers sound simple, but bar shape complicates the picture. Two bars with an identical stated reach and drop may feel different because of their bend, the angle of the ramps, the transition into the drops and where the brake hoods sit. This is why a handlebar should be considered as part of the complete cockpit, not chosen by dimensions alone.
Reach & drop explained in relation to bike fit
It is easy to confuse handlebar reach with frame reach. They are related, but they describe different things.
Frame reach is the horizontal distance from the centre of the bottom bracket to the centre of the top of the head tube. It helps describe the length of the frame independent of saddle position. Handlebar reach concerns the bar itself and changes the distance to your hands, particularly in the drops.
A frame that fits well can still feel too long if it is paired with a long stem and a bar with a deep forward sweep. Equally, shortening the bar reach can create useful room at the front without resorting immediately to a much shorter stem. That can preserve the steering feel intended by the frame while making the riding position more manageable.
There is no universal ideal. A flexible racer who spends long periods low and forward may be comfortable with a longer, deeper bar. An endurance rider who values several relaxed hand positions may benefit from a shorter reach and shallower drop. The important question is not whether one shape is more aggressive, but whether it allows you to use the positions you need without strain or compromise.
Why reach changes more than the drops
A shorter-reach bar can bring the hoods closer to the rider, depending on the bar shape and where the controls are fitted. If the hoods feel comfortable but the brake lever blades are hard to reach, check the lever shape and whether the controls have a reach adjustment. Check brake access from both the hoods and the drops.
It can also alter the sensation of the hood position. Modern brake hoods are not all the same length or shape, and their placement on the bar varies between groupsets and individual set-up. A bar that looks compact on paper may still feel long once the hoods are fitted. This is one reason a cockpit should be assembled and assessed as a system.
A longer-reach bar is not automatically a problem. Some riders prefer the additional space and the more extended position it creates in the drops. It may suit a rider with longer arms, good mobility and a clear preference for a race-focused position. It simply needs to be a deliberate choice rather than an inherited part of a standard specification.
Why drop affects confidence and comfort
Drop determines how much lower you are when riding in the drops, but its effect is not limited to flexibility. A deeper position changes how your weight is shared between saddle, pedals and hands. It may improve aerodynamics, but only if you can hold it comfortably and continue to steer, brake and look ahead with confidence.
If the drops are too deep for your current position, they often become an unused feature of the bike. The rider stays on the hoods during fast descents or into a headwind, not because they do not understand the benefits of the drops, but because that position feels too low or too stretched. A shallower drop can make the drops a genuinely useful all-day position rather than an occasional one.
Conversely, riders who race, time trial or ride quickly in groups may value a deeper drop because it gives a more meaningful change in height between the hoods and drops. Again, it depends on the rider’s mobility, saddle-to-bar drop, terrain and riding priorities.
The bar shape matters as much as the measurement
Compact bars have become common for good reason. Their shorter reach and shallower drop make the drops accessible for a wide range of riders, while still providing a purposeful low position. They are often a sensible starting point for road riders who want performance without making their cockpit unnecessarily demanding.
Traditional round-bend bars can offer a more gradual curve and a distinct feel in the drops. Some experienced riders prefer them, particularly if they are accustomed to that shape or enjoy riding with their hands low and well behind the brake levers. They are not outdated, but they are less forgiving of an unsuitable fit.
Ergonomic bars use shaped top sections and more defined bends to support the palms and create a particular hood position. They can be very comfortable, although comfort is personal. A flat, wing-shaped top may feel excellent on a long endurance ride for one rider and restrictive for another who moves their hands frequently.
For gravel riding, flare also enters the conversation. A flared bar widens towards the drops, giving more leverage and wrist clearance on rough descents. However, more flare is not always better. Excessive flare can make the brake levers feel oddly positioned on the hoods and may not suit riders who spend most of their time on tarmac.
How to choose the right reach and drop
Start with your current bike, if you have one. Consider where you naturally spend your time and where discomfort appears. Do you avoid the drops? Feel overextended on the hoods? Struggle to brake confidently from the drops? Or are you comfortable, but looking for a more aerodynamic position for racing? These observations are more useful than choosing a bar because it is fashionable or marginally lighter.
Your intended riding matters too. A rider tackling long sportives on rolling roads, from Devon lanes to long mountain descents overseas. A criterium racer may accept a lower, longer position if it supports their race posture and they can sustain it. A gravel rider may prioritise stability and hand clearance over a narrow frontal area.
Width should be assessed alongside reach and drop. A narrower bar can feel quicker and reduce frontal area, but it should not force your shoulders or compromise breathing and steering control. Wider is not universally more stable either, especially on the road. Shoulder width, riding style, terrain and personal preference all have a part to play.
It is also worth resisting the temptation to use a handlebar as the sole correction for a poor position. A very short-reach bar might mask a frame that is too long, while an exceptionally deep bar could be an attempt to create a lower front end on a bike that does not otherwise suit the rider. The most reliable result comes from looking at frame geometry, saddle position, stem, spacers, lever placement and bar shape together.
On a Redchilli build, David can use a cockpit that already works well for you as a reference. If the hoods feel right but you rarely use the drops, a different bend or shallower drop may give you a more useful lower hand position. With a one-piece cockpit, bar shape and stem dimensions are chosen together before assembly.
A Cockpit That Fits Your Redchilli
A well-chosen handlebar does not announce itself with a dramatic sensation. More often, the change is quieter. You use the drops without thinking about it. Your hands move naturally between the tops, hoods and lower positions. You can cover the brakes on a fast descent, settle into the wind and finish a long ride without feeling as though you have been holding yourself in the wrong place.
Tell David where your current cockpit feels comfortable and which hand positions you tend to avoid. Those details guide the choice of bar reach, drop and width alongside the stem and brake controls, with bike fitting where required. Each Redchilli is individually specified and hand assembled in Devon, so the cockpit suits the positions you use on the rides you do.
