Shimano Vertical PK7 Bike Back Wheel Replacement

Introduction

Use this guide to remove the back wheel of a Shimano Vertical PK7 bike.

There are a variety of reasons the back wheel may need to be removed or replaced. The wheel may be damaged (e.g. bent spokes), rendering the bike unusable and requiring the wheel to be replaced with a totally new one. Otherwise, the wheel may simply be misaligned with the brakes, which results in friction between the brakes and the wheel and causes an unsmooth, choppy, or elsewise uncomfortable riding experience; in this case, we are replacing the same wheel.

Note that there are several small pieces that need to be disassembled during the procedure, so keep track of all materials you detach from the bike.

For this guide, the only tool you will need at least two wrenches, one being an adjustable wrench (any kind should be fine).

What you need
