Tire Clearance - Cervélo R3 Rim Manual

TIRE CLEARANCE

Your Cervélo bicycle complies with the ISO 4210-2:4.10.2 standard for tire clearance. In order to comply with these safety standards and maintain your Limited
Lifetime Warranty, a minimum of 4mm of clearance must remain between the tire and any frame element. Due to the growing complexity of tire and rim interfaces,
Cervélo recommends identifying the available space before choosing a tire.

1. Measure the space between the chainstays at the
bottom-bracket junction.
2. Measure the space between the seatstays at the
top of the tire.
3. Using the smallest of those two numbers, subtract
8mm (4mm per side) to determine the remaining
space.
4. With the tire installed and fully inflated on your
wheel, measure the tire width to ensure that it fits.
Failure to follow these guidelines may result in
damage to the frame not covered by Cervélo
Limited Lifetime Warranty.
