Handles and handlebars
Handles and handlebars
If a garden hose develops a kink, the flow of water is interrupted. The same thing happens when nerves and blood vessels are unnaturally and permanently compressed or deflected. Where cyclists are concerned, the hands are particularly at risk. A sensation of tingling and numbness can be experienced.
The ideal countermeasure: the right handlebars and grips – both together support the wrists and hands in their natural posture and serve to relieve pressure.
Important: grips must be functional – non-slip, easy to grasp, pleasant to touch and extremely robust since they are exposed to all weathers. Just as important: grips must be ergonomic – suitable for the rider's hand size and shaped in such a way that the load is evenly distributed.Find out more
Ergonomic handle: the palm lies on an anatomically shaped handle. The contact surface is larger. This means: the pressure is more evenly distributed. The nerves and blood vessels are no longer squashed in the carpal tunnel.
Note: Rotate the handle into the correct position and fix it. This prevents the nerves and blood vessels in the wrist from developing a kink. The ball of the hand is supported ideally.
Incorrect position: Huge pressure on the flexed wrist and on the ball of the hand. The nerves and blood vessels develop a kink.
ergotec selection: You can choose from a selection of ergonomic handles in various shapes and materials. In the image: The MF handle is in a modular design and can be combined flexibly. Ask your bicycle dealer.
Curved handlebars are the best choice. The hand then rests on the grip in an anatomically correct position.
Straight handlebars only make sense on outright sports bikes because the steering behaviour is then felt and influenced more directly.
The curve of the handlebars depends on the riding style and size of the rider.
The smaller the upper-arm-torso angle is, the larger the curve of the handlebars should be.
Ideal: Pressure on the grip evenly distributed.
Lower arm and hand in alignment. The nerves and vessels run freely without any deflection.
Top right: Diagram of pressure measurement on the handle.
Critical: Pressure peaks at the grip.
Wrist (nerves/vessels) bent. A high muscular load is placed on the arm and shoulder.

Handlebars vary in width. Because we all differ in size! It’s the same as when buying clothes - you should always select the handlebars that are the right size for you (from XS to XXL).Find out more
The basic rule: The handlebar width should be the same as your shoulder width. This is measured on the body from shoulder joint to shoulder joint and on the handlebar from the middle of one hand to the middle of the other hand.
The width of the handlebar also changes the grip angles.
On the "wide" 650 mm handlebar: 16 degrees. On the "narrow" 570 mm handlebar: 8 degrees.
A multiposition handlebar offers the maximum dynamic variety for hands, arms and the back. It's worthwhile accepting the somewhat more complex-looking "cockpit". The gain is a vast improvement in comfort – particularly on longer rides.Find out more
With the lower grip position the upper body is more inclined, there is less air resistance when cycling. The fingers are ready to use close to the brake lever.
With the middle grip position the arms and wrists are naturally straight and relaxed. For fast rides or mountain biking. Variety for muscles and joints.
With the top grip position the upper body is upright and casually relaxed for slow rides.
Classic handlebar with just one grip position can be extended to provide two grip positions by adding bar ends (horns). This addition isn't costly and generally easy to retrofit besides.Find out more
The easy switching between flat and upright hand position prevents the fingers from getting tired and going numb.
Only available from ergotec: bar ends with ball joint.
Allows adjustment of any angle to achieve the rider's ideal position.

Three in one: Special additions allow classic handlebars to be upgraded from one to as many as three grip positions.Find out more
You can switch between three positions, meaning the combination is just as effective as a multiposition handlebar.
Thanks to the patented ball joint, the bar end can be individually adjusted, by 15° in the ball joint, continuously (360°) in the shaft and on the handlebar.
The handlebar height determines how much the torso is inclined. The torso inclination, on the other hand, decides which muscles are called upon and to what extent. Pain in the neck, shoulders and back is an indication of one-sided, i.e. uneven, loading.
The ideal countermeasure:: Muscle work must be harmoniously distributed! In this respect the following applies: in terms of body height, proportions and performance capability every person is different. Here we show how the handlebar height can be adjusted for the different stem constructions.
Classic construction: the shaft and stem are permanently connected as one single component. The stem shaft inserts into the "fork tube” (steerer) and is held in place by means of a clamp bolt and expander cone.Find out more
The classic design's components.
Lowering the handlebars. The clamp bolt and expander cone are loosened. The stem shaft is inserted deeper. The bolt is retightened.
Raising the handlebars. The clamp bolt and expander cone are loosened. The stem shaft is extended upwards. The bolt is retightened. Attention: Observe the minimum insertion depth. ergotec has quill stems of varying lengths.
ergotec selection: There are classic stems with short and long shafts (up to 300 mm), with stem projections of varying lengths, adjustable in the angle or rigid in black or silver. Ask your bicycle dealer.
Ahead construction: the fork tube towers above the frame's "head tube". The stem is mounted to the "head" at the end of the fork tube and fixed in place with a clamp. If the fork tube is long enough, the height can be altered accordingly using spacers.Find out more
The ahead design's components.
When you disassemble the stem and spacer then the front wheel fork tube is visible.
If spacers are assembled then the height can be lowered by removing the spacers. The protruding fork tube is removed (by the bicycle dealer).
Afterwards the handlebars can no longer be raised (except using special adapter solutions from ergotec).
If the bike has a stem with adjustable angle, then the position of the handlebars can be precisely “fine-tuned”. Angle adjustment is possible in both ahead stems and quill stems.Find out more
To adjust the angle: loosen the bolts. Set to the desired angle. Retighten the bolts.
There are also quick release solutions from ergotec that do not require any tools.
With an angle setting of 60 degrees the handlebar is significantly further back and higher, the upper body is more upright.
With an angle setting of 0 degrees the handlebar is significantly further forward and lower, the upper body is more bent.
The figure shows an example of an angle setting of 40 degrees.
Attention! If the angle is adjusted, two factors also change: the height of the handlebars and the distance of the handlebars to the saddle.
That's why: first set the handlebar height via the shaft length. And then "fine-tune" by adjusting the angle.
For ahead designs: Using the Up&Down adapter from ergotec, the handlebar can be set higher or lower at any time with one simple movement (no tools required).Find out more
The ahead stem is assembled at the top.
The adapter is clamped on the fork tube instead of the stem.
Using the quick release you can adjust the height at any time without any tools.
Lowering the handlebars
Open the quick release, push the steering unit deeper down.
Close the quick release. All done!
Raising the handlebars
Open the quick release, extend the steering unit upwards, close the quick release. All done!
The adapter can be continuously adjusted over a range of 100 mm.
A cheaper alternative if you only want to achieve a fixed handlebar height.
AHS Superlight: Continuously adjustable handle angles. Almost any handles and bar ends can be assembled. Compatible with any gear and brake systems.Find out more
The grip angles can be freely adjusted.
The ergonomic grips MF1 (without handlebar horn/bar end) or MF2 (with handlebar horn/bar end) are easy to fit.
An additional benefit: handlebars "fold in". For transporting on car bicycle carriers or space-saving winter storage, e.g. in the garage.
AHS Basic: Light multiposition handlebar. Two shapes to choose from: Comfort or Sport. Continuously adjustable angle of handles.Find out more
Triple choice of handles. Easy, extremely safe assembly of handles. Huge advantage of these "push-on" multiposition handles: grip shifters can also be assembled without any problems!
