Tire/Rim Clearance; Intended Use Of The R5-Cx Bicycle - Cervélo R5-CX Assembly Manual

TIRE/RIM 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 widest of the rim or tire
width to ensure that it fits.
Contact between the tire or rim and the
frame or fork may result in a loss of control
while riding and potentially serious injury.
Failure to follow these guidelines may result
in damage to the frame not covered by
Cervélo Limited Lifetime Warranty.

INTENDED USE OF THE R5-CX BICYCLE

Understand your bike and its intended use. Choosing the wrong bicycle
for your purpose can be hazardous. Using your bike the wrong way is
dangerous.
No one type of bicycle is suited for all purposes. Your retailer can help you
pick the "right tool for the job" and help you understand its limitations.
There are many types of bicycles and many variations within each type.
There are many types of mountain, road, racing, hybrid, touring, cyclocross
and tandem bicycles. There are also bicycles that mix features. For
example, there are road/racing bikes with triple cranks. These bikes have
the low gearing of a touring bike, the quick handling of a racing bike, but
are not well suited for carrying heavy loads on a tour. For that purpose you
want a touring bike.
Within each of type of bicycle, one can optimize for certain purposes. Visit
your bicycle shop and find someone with expertise in the area that interests
you. Do your own homework. Seemingly small changes such as the choice
of tires can improve or diminish the performance of a bicycle for a certain
purpose.
NOTE: Usage conditions are generalized and evolving. Consult
your retailer or Cervélo Customer Service about how you intend
to use your bike.
NOTE: Cervélo bicycles are tested to a maximum combined
bicycle/rider/luggage weight of 100kg. Components have
different weight limits, and if replaced can alter the maximum
safe bike weight limit. Consult your retailer or Cervélo
Customer Service about what components are appropriate for
your bicycle.

Cyclocross Riding - Condition 2
Bikes designed for riding Condition 1, plus unpaved and gravel roads and
trails with moderate grades. Contact with irregular terrain and loss of tire
contact with the ground may occur. Drops should be no more than 6" (15cm).
Intended For cyclocross riding, training and racing. Cyclocross involves
riding on a variety of terrain and surfaces including dirt or mud surfaces.
Cyclocross bikes also work well for all weather rough road riding and
commuting.
Not Intended For off road or mountain bike use, or jumping. Cyclocross
riders and racers dismount before reaching an obstacle, carry their bike
over the obstacle, and then remount. Cyclocross bikes are not intended for
mountain bike use. The relatively large road bike size wheels are faster than
smaller mountain bike wheels, but not as strong.
