When attaching your bike to your indoor trainer the bike will be tilted slightly forwards. To make sure your bike is perfectly horizontal, just like you are riding outside, our WheelBlock will even it out. The WheelBlock keeps your bike horizontal and prevents it from sliding forwards or backwards. It will also keep your handlebars from rotating and makes sure your tire will not damage the floor. Compatible with both road bikes and mountain bikes.

• An easy way to stabilize your indoor cycling setup
• Fits both road and mountain bike tires
• Rubber anti-slip feet ensures the block stays in place
