STEP 2: Input Rim Dimensions - Please read the following information.

• Measure rim depth. Rim depth includes brake track as pictured below. Most rim manufacturers publish this information for aero wheels.

• Measure rim width at the widest point. 
• Any additional information about your wheel Brand, Make, Model, and Year should be input in the text field.

What's Included:

• Drive side cover: flatter disc half; has "align valve stem here" decal.
• Non-drive side cover: lens-shaped disc half; has valve stem hole cutout.
• 10 plastic fasteners: (male/female screw post fastener pairs); 8 to do the job + 2 spares. Additional hardware is available.
• 2 valve hole cover: vinyl adhesive backed material.

Common Accessories:

• You will need to remove your cassette to install the Aero Disc Cover. Cassette removal tools are sold separately.
• When you race with a disc wheel, you'll need a 90-degree pump adapter to access your valve with a standard pump. 
• Ordering: Please provide wheel and hub  BRAND, MODEL and YEAR if possible for your rear wheel.  We trim each cover individually based on the dimensions of your wheel and hub information. Please use the text fields at the bottom for any additional instructions or information about your wheel.

Important: 

• The covers might not lay completely flat when they are trimmed extremely small. This applies to very deep profile rims in excess of 80mm.
• A rim height of at least 16mm is required.
• Disc covers are not intended for continuous training use. Remove covers between races.
• DO NOT use Loctite on fasteners. Loctite will disintegrate the cover material and cause fasteners to pull through.
• AeroJacket Disc Covers take 2-3 business days (M-F) to fabricate. Please account for 2-3 business days (M-F) fabrication time when choosing an appropriate shipping method.
