## Abstract

A steering system for bicycle handlebars comprises a holding element fixed to the steer tube, in particular above an upper bearing element. A fixing element is arranged between two bearing elements. The fixing element is not directly connected to the steer tube, but is connected, in particular by form-fit, to the holding element by means of a connection means.

## Claims

### Claim 1

A steering system for bicycle handlebars comprising
a steer tube pivotably supported in a head tube of a bicycle frame via two bearing elements,
a holding element fixed on the steer tube in particular above the upper bearing element,
a fixing element arranged between the two bearing elements, preferably for connecting to a steering stabilization means, and
a connection means connecting the fixing element to the holding element.

### Claim 2 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the holding element is fixed to the steer tube in a clamping manner.

### Claim 3 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the connection means is designed as a rotatory connection for transmitting moments, the connection being implemented in particular by form-fit.

### Claim 4 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the connection means comprises a connection ring surrounding the steer tube and comprising protrusions and/or recesses for a form-fitting rotatory connection, which cooperate with recesses and/or protrusions of the fixing element.

### Claim 5 (depends on 4)

The steering system for bicycle handlebars according to claim 4, wherein the connection ring is connected to the holding element in particular in a form-fitting manner, in particular via protrusions and recesses provided in the connection ring, which cooperate with recesses and/or protrusions provided in the holding element.

### Claim 6 (depends on 4)

The steering system for bicycle handlebars according to claim 4, wherein the connection ring has an at least partly annular outer surface on which the upper bearing element abuts.

### Claim 7 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein a longitudinal holding element for holding the fixing element in the axial direction of the steer tube.

### Claim 8 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the steering stabilization means comprises a spring element.

### Claim 9 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the steering stabilization means is at least partly arranged in the top tube of the bicycle frame.

### Claim 10 (depends on 1)

The steering system according to claim 1, wherein the steering stabilization means comprises two in particular band-shaped stabilization elements which are connected to the fixing element preferably opposite each other.

### Claim 11 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the holding element and/or the connection ring comprise a recess for passing lines therethrough.

### Claim 12 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the holding element is designed as a first stop element and/or is connected to a first stop element, the first stop element comprising two stops and cooperating with a second stop element.

### Claim 13 (depends on 1)

The steering system according to claim 1, wherein the second stop element is adapted to be arranged in a recess in the bicycle frame, in particular in the top tube of the bicycle frame.

### Claim 14 (depends on 1)

The steering system for bicycle handlebars according to claim 1, wherein the second stop element comprises a retaining element adapted, in particular, for insertion into the recess, and a stop connected to the retaining element.
