Bike Wheels

Tire dimensions 

• Road bikes: Diameter (mm) x width (mm) e.g. 700x23
• Mountain bikes: Diameter (inches) x width (inches) e.g. 25x2.0
• As long as the diameter and size match your current wheel, any width should be fine.

Tire type 

• Clincher: Check your valve—Schrader or Presta—it must match the hole in your wheel’s rim
• Tubeless: You’ll need tubeless-compatible wheels and tire sealant

Brake Type 

• Rim brakes: These must be paired with a wheel with a flat rim sidewall
• Disc brakes: Wheels must be compatible, including rotor type

Rear Hub Type 

• Freehub: Spline fits into the center of your rear cassette, which usually has a lock ring to secure it to the freehub
• Threaded hub: Found on older bicycles; will accept any type of threaded freewheel cluster
