What to Compare Before Buying
- Size and clearance: Confirm that 700 x 45C is accepted by your bicycle and that the frame and fork have clearance for this tire size.
- Rim and setup: Check the exact tire and rim requirements for your intended setup. If you plan to ride tubeless, confirm that this specific version is compatible with your rim and tubeless setup.
- Quantity: This is one tire. Check whether you need one replacement or a pair.
Compatibility, Size and Fit
The 700 x 45C marking does not by itself establish fit on a particular bicycle. Check the bicycle and rim documentation for accepted tire sizes and setup requirements. Do not assume compatibility with every tubeless rim or setup.
Choosing the Correct Version
Match the GKSK Classic name, RF745-GKSK-D2 part number, 700 x 45C size and black/brown color when identifying this version. Confirm its tubeless compatibility for your exact rim if that setup matters to you.
Before You Decide
Confirm bicycle and rim fit, including frame and fork clearance, and make sure one tire is the quantity you need.
