Setting up drop bars

Explanation of various hand positions and grips on the bars is in this post: Road bar hand positions
In case no set up enables comfortable position, perhaps a bar with a different shape is needed. This post explains different road bar geometries: Road bar geometry

This post addresses setting up drop bars (road bicycle handlebars). Many people, especially those used to flat bars, coming from city, or mountain bikes, have problems setting up comfortable position on a road bike. Some things are not intuitive enough and require a lot of experience, trial and error to get them right. This article is a shortcut.  🙂

TL/DR

Here I’ll try to help you get comfortable on your road bike. Briefly put:

Road bar setup it not very intuitive, so I recommend a “general” setup that works for most people. Even if that doesn’t work for you 100%, it is a good starting point for fine-tuning the setup to match your body and preferences.

I also hit the high-points of the common discomfort and pain causes.

Make sure to do one change at a time after the initial setup (slower and gradual does it) and ride a lot in between changes to test and confirm if your comfort is improved, or you should make adjustments in the opposite direction. 🙂

0. Starting notes

  • This sounds stupid and obvious, but: don’t adjust handlebars while riding. If you get impatient and tempted to try a new angle for example as soon as possible, on the go, remember this.  Make sure all the bolts are fastened tight before going for a test ride. Always.
  • Don’t make adjustments away from home. I case a bolt threads strip, or a cable gets pinched, snaps – it is better not to risk being left stranded on the road. Preferably make adjustments during local bike shop working hours – just in case. 🙂
  • Get proper tools before starting. In the “heat of the moment” one can easily reach for a small flat bladed screwdriver in stead of a phillips, for example, “it will hold”. So inspect all the bolts on and around the handlebars and make sure you have all the right tools. Usually it is allen wrench 4, 5 and 6, flat and phillips screwdriver 1 and 2. But do check.
  • When tightening, if you don’t have experience, use a torque wrench and follow producers torque recommendations. This is critical with carbon parts.
  • If moving brake levers, bar tape will need to be unwrapped, then wrapped back again. It does get damaged when doing so. Do a few test rides to make sure the fit is right, before putting a new tape on the bars.

1. Available bar adjustments

Adjustments can be made to bar height, distance from the steering axle (and saddle), and angle.


1.1. Bar height

Depending on fork type, there are two standards and two ways of height adjustment. Explanation how to adjust height can be found in this post: Bar angle and height adjustment.

Depending on fork type, procedure for height adjustment differs. Bars are set to the desired height.

1.2. Steering axis distance

This is altered with changing the stem (length).

1.3. Bar angle adjustment

By loosening bolts holding the bars to the stem, bars can be rotated upwards-downwards.

Bars can be rotated up or down. Bars on the right are rotated upwards compared to the ones on the left.

2. Position adjustment

Before adjusting bars, make sure the saddle is properly set up, using these instructions:  Setting up riding position – bike fitting.


2.1. Bars height

Set bars height so that top of the bars is about one or two cm below saddle height.

As a starting position, bars drop should be a few cm at most, or even level with the saddle height.
As a starting position, bars drop should be a few cm at most, or even level with the saddle height.

For riders who aren’t super-fit or competitive: if you can’t comfortably ride in the drops, it can be a good idea to set the top of the bars a few inches above the saddle height. That way, you will be able to use the drops normally (which allows you stronger braking and a more stable grip). If reaching the drops is a problem, or if pedalling when in the drops isn’t comfortable or possible, there’s no shame in raising the bars. I see far too many road cyclists using the tops exclusively, even during descents, because the bars are set too low for them (pun not intended 🙂 ).

“Aggressive,” racer-like low bar height shouldn’t be used if it’s not beneficial to the rider. A bike should fit you, not the other way round. Besides, you get more aero, and finer control, if your bars are set high enough for you to reach the drops with bent elbows, than if you have to stretch your hands straight in the elbows in order to reach the drops.

2.2. Bars angle

Start with loosening stem bolts that hold the bars, so they can be rotated.

Bolts clamping the bars. Loosen them all equally by little. When fastening, fasten the opposite bolts, until all are tight.

Don’t worry about brake lever, just rotate the bars so they are comfortable and feel natural in the drops. Set position and fasten bolts. Comfortable position is usually when the lowest part of the bars is parallel to the ground, or points slightly downwards (towards the rear wheel axle, or a bit higher). But the only correct position is the one that feels comfortable and natural to the rider.

– T.O.C. –


2.3. Stem length

Sit on the bike, hold the bars in the drops, with hands slightly bent at the elbows. The bars should be blocking the view of the front wheel axle – it shouldn’t protrude from the bars by a lot in any direction (in front or behind).

View of the front wheel axle over the bars. In the picture, up is the front side of the bike. This stem is on the border of being too short, but not too much of axle protrusion is visible so it's probably acceptable.

This stem is on the border of being too short, but not too much of axle protrusion is visible so it’s probably acceptable.
  • If the wheel axle is too far in front of the bars, the stem is probably a cm or two too short.
  • If the axle is far behind the bars, the stem is too long for a few cm.

This is just a guideline method. Only extreme misalignment should be dealt with. If it’s like in the picture above, don’t change the stem before a long test ride and doing some other tweaks explained here. The most valid test is a test ride. If during a test ride, rider feels cramped, like bars are too close and the front axle is seen in front of the bars (like in the picture above), stem is definitely too short. If, on the other hand, the rider feels too stretched in order to reach the bars and the front axle is visible closer than the bars (opposite side to the one in the picture above), the stem is too long.

What this looks like is shown and explained at 7:40 to 11:20 in this video (it also explains road bicycle frame sizing):

2.4. Test ride

Now take a test ride. Check if all the bolts are tight. The emphasis is still on the drops. Brake levers should be left as they are for now. This position should be comfortable for over 20 minute ride period (in the drops).

Rather aggressive riding position in the drops. Torso is almost level with the ground. Less flexible riders might prefer bars a bit higher set.

If the neck is stiff from looking ahead and bending it during riding, bars could be set too low. Try raising them for a few cm and try again.

If there’s pressure on palms and hands, first check if the saddle nose is tilted down. If it is, make sure the saddle is level with the ground. Then, check if the saddle isn’t placed too far forward in the post rails. Perhaps a post with a (bit more) setback is needed. If there is hand pressure with a saddle level, move the saddle 1 cm behind KOPS position for a start.

Then take another test ride. If the pressure on the hands persists:

  • if the top of the bars is level with the saddle (or even higher), lower them for a few cm.
  • if the top of the bars is lower than the saddle, first try lifting bars for a few cm.

Now check for bar angle once more, step 2.2. Take a test ride again and see if the situation is better or worse. If it’s gotten worse, then change bar height back to the way it was, and then further a few cm in the opposite direction (if it was lowered, raise it and vice-versa).

After a number of iterations, a comfortable drops position will be found. Give it time and patience, don’t expect to get it right at first. Just make sure you’re making progress, getting comfier and more natural with each alteration. Experienced bike fitters can often just by looking at a rider on a bike get a 90% of the optimal setup – so the rider can just do minor tweaks later.

After a comfortable position in the drops was found, it is time to set up brake levers.

2.5. Adjusting brake levers position

Unwrap the bar tape, then loosen clamp holding the levers. The procedure of loosening the clamp differs with type of brake levers. Check the user manual for the model on your bike. Usually it is a 5 mm allen screw, but not always.

Next, set levers so that the top part is level with the ground, or pointing upwards by a few degrees. Never pointing down. Brake levers should be about vertical. Remember to tighten the lever clamps.

Flat part for hand is a few degrees upward.

Bars in the pics above are modern, compact handlebar geometry. The hoods are almost in line with the top part of the bars before them. With classic curved bars, there will be a drop before the levers, which are mounted to be level on these bars as well. Here’s what it looks like:

Top part of the levers is almost level. Because of different bar shape, it appears as if levers are pointing up, more than they actually are.

Some riders prefer this curve. Other prefer tops to be flat – in line. Changing this requires bar change.  🙂

When it’s set up like this, levers are easily reachable both from the drops and from the tops (hoods). Riders with smaller hands might prefer setting brakes so that pads start braking when the lever is pulled by a cm or more, when they get the hold of the levers with whole fingers.

Brakes set to grab when levers are pulled in a bit. MAKE SURE not to overdo it, there must be enough lever travel left for hard braking!

Brake lever setting up put into numbers, just for orientation:

The main merit is the rider. This is just for orientation, some average, "perfect" positioning.

Here’s what should be gained in practice:

Hoods grab: Wrists are almost straight, elbows slightly bent, natural, comfortable position.

Grab from the drops: Wrists are slightly bent, elbows a bit more. It should feel natural, without too much twisting.

Finally, a “secret” that not everyone tells: levers can be set to be 100% natural and comfortable only for one position: hoods, or the drops. The other grab will be about 80% from perfect when everything is set up correctly. So either choose which position is more important to be set up perfectly, or go for a compromise, with both positions being about 90% perfect, but not 100%.

  1. Relja, great help- your page come on top of Google search 😉

    I am trying to resolve my “small hands problem” for shop bought, (despite promised no time spent on) “fitted” bike. I just cant reach brakes and will start working from your list.

    Also…amazing suprise to see your name and go to your main page, than seeng Djava and remembering my silver Rog bike driven down Futoška many moons ago.
