Compatibility, Size and Fit
These pads are specified for V-brakes. Check that your bicycle has V-brakes, then compare the 70 mm size and pivoting-post mounting arrangement with the pads your brake accepts. A matching brake type alone does not confirm that the size and mounting fit.
What to Compare Before Buying
- Brake system: Confirm that the bicycle uses V-brakes rather than disc brakes.
- Size and mounting: Check the required pad length and whether your brake accepts pivoting posts.
- Variant color: Confirm the body and pad colors for the selected variant if they matter to your build.
The pivoting posts are described as aiding installation and toe-in adjustment. Follow the manufacturer’s instructions for installation and adjustment.
Before You Decide
Confirm V-brake compatibility, the 70 mm size and the required mounting arrangement. Check the selected variant’s color if that is important to your build.
