## Abstract

A chainguide includes a mounting bracket and a guide member supported by and infinitely laterally adjustable relative to the mounting bracket.

## Claims

### Claim 1

A chainguide, comprising:
a mounting bracket; and
a guide member supported by and infinitely laterally adjustable relative to the mounting bracket.

### Claim 2 (depends on 1)

The chainguide of claim 1, wherein the guide member includes non-shimmed lateral adjustment.

### Claim 3 (depends on 1)

The chainguide of claim 1, wherein the guide member is infinitely laterally adjustable relative to the mounting bracket along an axis, and the guide member is rotatable relative to the mounting bracket about the axis.

### Claim 4 (depends on 1)

The chainguide of claim 1, wherein the guide member includes an outer guide and an inner guide providing a guide channel for a chain therebetween.

### Claim 5 (depends on 1)

The chainguide of claim 1, further comprising:
an expanding mandrel extended from the mounting bracket,
the guide member slidably supported on the expanding mandrel.

### Claim 6 (depends on 5)

The chainguide of claim 5, wherein the expanding mandrel has an unexpanded state in which the guide member is slidable and infinitely laterally adjustable relative to the mounting bracket, and an expanded state in which the guide member is fixed in a lateral position relative to the mounting bracket.

### Claim 7 (depends on 5)

The chainguide of claim 5, further comprising:
a guide sleeve slidably supported on and non-rotatably coupled with the expanding mandrel,
the guide member supported by and rotatable relative to the guide sleeve.

### Claim 8 (depends on 7)

The chainguide of claim 7, wherein the guide member has a rotatable state in which the guide member is rotatable relative to the guide sleeve and a non-rotatable state in which the guide member is non-rotatable relative to the guide sleeve.

### Claim 9 (depends on 7)

The chainguide of claim 7, wherein the expanding mandrel and the guide sleeve have an elliptical coupling.

### Claim 10 (depends on 7)

The chainguide of claim 7, wherein the expanding mandrel and the guide sleeve have a splined coupling.

### Claim 11 (depends on 1)

The chainguide of claim 1, wherein the mounting bracket is to mount the chainguide on a bicycle, and the guide member is to retain a chain on a chainring of the bicycle.

### Claim 12

A chainguide, comprising:
an expanding mandrel;
a guide sleeve supported by the expanding mandrel; and
a guide member supported by the guide sleeve,
the guide member rotatable relative to the guide sleeve,
the guide sleeve non-rotatable relative to the expanding mandrel,
the guide sleeve and the guide member jointly slidable along the expanding mandrel, and the expanding mandrel expandable to fix the guide sleeve and the guide member at a position along the expanding mandrel.

### Claim 13 (depends on 12)

The chainguide of claim 12, wherein the guide member includes a guide channel for a chain.

### Claim 14 (depends on 12)

The chainguide of claim 12, wherein the guide sleeve and the guide member are infinitely laterally adjustable along the expanding mandrel.

### Claim 15 (depends on 12)

The chainguide of claim 12, wherein, with the guide sleeve at a fixed position along the expanding mandrel, the guide member is rotatable relative to the guide sleeve.

### Claim 16 (depends on 12)

The chainguide of claim 12, wherein the guide member is securable to the guide sleeve for non-rotation relative to the guide sleeve.

### Claim 17 (depends on 12)

The chainguide of claim 12, further comprising:
a mounting bracket to mount the chainguide,
the expanding mandrel extended from the mounting bracket.

### Claim 18 (depends on 17)

The chainguide of claim 17, wherein the guide member is vertically adjustable with the mounting bracket.

### Claim 19 (depends on 17)

The chainguide of claim 17, wherein, with the guide member at a fixed vertical position by the mounting bracket, the guide member is adjustable along the expanding mandrel and rotatable relative to the guide sleeve.

### Claim 20 (depends on 17)

The chainguide of claim 17, wherein the mounting bracket is to mount the chainguide on a bicycle, and the guide member is to retain a chain on a chainring of the bicycle.
