Press the Di2 battery into the Seatpost Internal Battery Mount (MT-BINT-SP2) and attach the E-wires according to manufacturer instructions. Insert the assembled battery and holder into the seatpost. 24 TOP TUBE SMARTPAK INSTALLATION 10 mm Ensure that Top Tube storage is installed leaving a minimum of 10 mm separating it from the rear surface of the handlebar stem. Failure to do so may interfere with steering, and result in an accident . If not using Smartpak 400A install adhesive Bottle Boss Cover Plate (CVR-WB). 25 M5 x 18 mm Torque to 1-2 N·m M5 Washer Smartpak 400A Top Tube Storage (SB-SB05-TT) 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 6 mm 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. Tire/Rim Frame Dimension Clearance 6 mm 6 mm 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 smaller of those two numbers (Frame Clearance), subtract 12 mm (6 mm per side) to determine the maximum AllowableTire/Rim Dimension. 4. With the tire installed and fully inflated on your wheel, measure the greater of the rim or tire width and ensure it is less than the calculated AllowableTire/Rim Dimension width to ensure that it fits. 5. If a 6 mm Allen key does not fit into the smallest gap then the tire clearance is insufficient. 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. 26 AERO THRU-AXLE INSTALLATION 6 mm Allen key / torque wrench or Tighten front axle to 12-15 N·m. To secure wheels, install the greased axle, through the drop out and the wheel hub, aligning the threaded end of the axle with the threaded insert. Once aligned and engaged, thread the axle (clock-wise) into the threaded component of the insert until the axle is secured tightly. To ensure rider safety, it is critical to install the Cervélo Aero Thru-Axle correctly. Failure to do so may result in an accident with potential for serious injury to the rider. Tighten front axle to 12-15 N·m. Ensure thru-axle washer is present for installation. Cervélo Aero Thru-Axle with Removable Handle (QRA-AERO2-F) and Cervélo Road UDH Rear Aero ThruAxle with Removable Handle (QRA-698) Ensure thru-axle washer is present for installation. 27 28 INTENDED USE OF THE ÁSPERO 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 100 kg. 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. Maximum Weight Limit - Cervélo Áspero Rider 194 lbs 88 kg Gear* 11 lbs 5 kg Total 220.5 lbs 100 kg *Seat bag / water bottles / bento bag / handlebar bottle / storage mounts only General Purpose 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" (15 cm). Intended For paved roads, gravel or dirt roads that are in good condition, and bike paths. Not Intended For off-road or mountain bike use, or any kind of jumping. Not Compatible with touring racks or panniers, child seats, or trailers. Some bikes come with relatively wide tires, well suited for gravel or dirt paths. Some come with relatively narrow tires, best suited to faster riding on pavement. If you ride on gravel or dirt paths, carry heavier loads, or want more tire durability talk to your Authorized Retailer about wider tires. Replacement of tires or cranks with components of different sizes can reduce the available toe clearance and result in "toe overlap". 29 ÁSPERO TORQUE SPECIFICATIONS Correct tightening torque of threaded fasteners is crucial to your safety. Always tighten fasteners to the correct torque. In case of a conflict between the instructions in this manual and those provided by a component manufacturer, consult with your retailer or with Cervélo Customer Service for clarification. Fasteners that are too tight can stretch and deform. Fasteners that are too loose can move and fatigue. Either mistake can lead to a sudden failure of the fastener. Use only a correctly calibrated torque wrench to tighten critical fasteners on your bike. Carefully follow the torque wrench manufacturer's instructions on how to set and use the tool for accurate results. Ensure you read all relevant documentation and have the correct tools prior to attempting any adjustments yourself. It is recommended that you permit your retailer to perform the following adjustments, as they have the proper tools and experience to ensure it is done correctly. Prior to assembling and tightening any bolts, all threads must be generously greased with a quality, non-lithium type grease (Park Tool HPG-1 or equivalent) unless the bolt is pre-coated with Loctite® thread locker. All bolts should have either grease or Loctite - but never both. Torque wrenches with scale appropriate for the particular torque setting are strongly recommended for tightening all threaded fasteners. Cervélo strongly recommends the use of carbon assembly compound/friction paste (Dynamic Assembly Compound Carbon or equivalent) for all areas of clamping to carbon fiber, such as the seatpost to frame, the stem to fork, and the handlebar to stem joints. Benefits to using this paste include reduced corrosion potential, and a decrease in required clamping force needed to support a given load. The paste should be evenly spread on the carbon surface under the clamped area, and the applicable bolt tightened as per the following recommendations. In case of a disagreement or a conflict between the following list and any supplier literature on recommended torque values for original equipment components, please contact Cervélo Customer Support for review and clarification of the required torque prior to installation.
