GENERAL INFORMATION

INTENDED USE CONDITION 2

GENERAL PURPOSE RIDING

Bicycles designed for riding Condition 1, plus smooth gravel roads and improved trails with moderate grades where the tires do not lose ground contact. These bicycles are intended for paved roads, gravel or dirt roads that are in good condition, and bicycle paths. These bicycles are NOT intended for off-road or mountain bicycle use, or for any kind of jumping. Some of these bicycles have suspension features, but these features are designed to add comfort, not off-road capability. Some come with relatively wide tires that are well suited to gravel or dirt paths. Some come with relatively narrow tires that are 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 Specialized Retailer about wider tires.

For more information on the intended use and structural weight limits for the frame and components, please refer to the Owner's Manual.

WEIGHT LIMITS

CARGO WEIGHT LIMIT: The maximum cargo weight the bicycle is designed and tested to support structurally.
STRUCTURAL WEIGHT LIMIT: The maximum total weight (rider, bicycle, and cargo) the bicycle is designed and tested to support structurally.

The specified cargo weight limit applies only to cargo carried through the use of compatible equipment and seat bags. If the cargo weight limit of the bicycle differs from the cargo weight limit set by the rack or seat bag manufacturer, always use the lowest limit. If you add any other load-bearing accessories, including, but not limited to, baskets and child carriers, you do so at your own risk in that these accessories have not been tested for compatibility, reliability, or safety on your bicycle. Failure to follow this warning may result in serious personal injury or death.

Attaching items such as panniers, bags, water bottle cages, storage boxes, racks, or fenders to your bicycle can damage the frame. Using frame protection, such as protective decals, may help prevent damage from occurring.
For more information on the intended use and structural weight limits for the frame and components, please refer to the Owner's Manual.

GEOMETRY

SPECIFICATIONS

PARTS SPECIFICATIONS

*Not all models are equipped with all the above components.
All models are compatible with electronic shifting (wired or wireless) and are compatible with 1x mechanical configurations.

TORQUE SPECIFICATIONS

Correct tightening force on fasteners (nuts, bolts, screws) on your bicycle is important for your safety. If too little force is applied, the fastener may not hold securely. If too much force is applied, the fastener can strip threads, stretch, deform, or break. Either way, incorrect tightening force can result in component failure, which can cause you to lose control and fall. Where indicated, ensure that each bolt is torqued to specification. After your first ride, and consistently thereafter, recheck the tightness of each bolt to ensure secure attachment of the components.

Ensure that all contact surfaces are clean and bolt threads are greased or have a thread-locker compound (refer to the instructions for each bolt) prior to installation.
Many bolts have a blue thread-lock patch on the threads to help secure the bolt under torque. Repeated installation and removal of a bolt may reduce the effectiveness of the patch. However, it can be replaced with the application of a liquid blue thread locker.

GENERAL NOTES ABOUT ASSEMBLY

This manual is not intended as a comprehensive assembly, use, service, repair, or maintenance guide. Please see your Authorized Specialized Retailer for all service, repairs, or maintenance. Your Authorized Specialized Retailer may also be able to refer you to classes, clinics, or books on bicycle use, service, repair, and maintenance.
In order to successfully build your bicycle, it's very important to follow the order of operations as outlined in this manual. Modifying the order of assembly will result in a longer build process.
Assembly of the front end of the bicycle is easiest with the rider's fit already determined (the steerer tube doesn't need to be cut at this time; it can stick out the top of the stem) prior to routing all the housings and wires through the frame and fork. To determine fit, it's recommended to use a fit tool. If this isn't possible, perform a basic assembly of the wheels, drivetrain, and front-end components without the brakes and housings. Once the fit is complete, all the components need to be removed in order to route the housings and wires.
Many bolts have a blue thread-locker patch on the threads to help secure the bolt under torque. Repeated installation and removal of a bolt may reduce the effectiveness of the patch. However, it can be replaced with the application of a liquid blue thread-locker.

TIRE SIZES

Tire sizes vary significantly from brand to brand. CEN standards require a minimum of 6 mm of clearance between the frame/fork and the tires. When choosing a wheel and tire combo, factor in enough clearance for the conditions, setup, and wheel flex.

BOTTOM BRACKET

ƒThe Crux frame uses a 68 mm standard BSA threaded design bottom bracket.
ƒBefore installing the bottom bracket (BB) and crank, make sure all housings and wires are routed through the frame.
ƒGrease the threads, install the BB, and torque according to the manufacturer's instructions.

Do not face the bottom bracket shell! This can prevent proper installation of the crank. Your Specialized frame does not require any bottom bracket shell pre-installation preparation, as all surfaces have been precisely machined to specific tolerances at the factory for proper interface with a compatible crankset. Please refer to the manufacturer's instructions for crank and bottom bracket installation.

Always use a bottom bracket equipped with a sleeve between the two cups. Running a bottom bracket without the sleeve can result in housings and/or wires contacting the bottom bracket spindle, which can result in wear.

RECOMMENDED TIRE PRESSURES

The tires must be inflated, periodically checked, and re-inflated using a pump with an accurate pressure gauge.
Pump the tires up to your desired pressure. Refer to the tire's sidewall for pressure range. Check your wheel manual or decal on the rim itself to see if your wheels have a maximum pressure limit. Do not exceed it.

Never inflate a tire beyond the maximum pressure marked on the tire's sidewall or the maximum pressure limit specified by the wheel manufacturer, whichever is lower. Failure to follow this warning may cause the tire to blow off the rim and may result in serious personal injury.

BRAKE AND SHIFT ASSEMBLY

SHIFTING - ELECTRONIC WIRED SYSTEM

FRAME WIRING LENGTHS

BRAKES

Route the rear brake hose:

• Route the rear brake hose through the chainstay ICR port, over the bottom bracket shell, and up the down tube.
• Install a churro (foam sleeve) over the brake housing and into the down tube.
• Route the brake hose out of the head tube ICR port.
• Install a grommet over the brake housing and into the head tube ICR port.
• Install the caliper on the chainstay.
• Complete the rear brake installation according to the brake manufacturer's instructions.

Route the front brake hose:

• Run the front brake hose in through the lower ICR port in the fork and guide it up the fork leg until it exits at the ICR port on the fork crown.
• Install a grommet over the brake housing and into the upper fork ICR port.
• Complete the front brake installation according to the brake manufacturer's instructions.

SEATPOST ASSEMBLY

Most models come with the Terra seatpost (5.5.2).

ALPINIST SEATPOST

• Grease and install the M6 barrel nut (C) inside the seatpost.
• Grease and assemble the M6 bolt (A) and M6 cradle washer (B), then install them in the upper cradle.
• Using a 5 mm Hex key, torque the M6 bolt (A) to 26.5 in-lbf / 3 Nm.
• Install the lower cradle, followed by the saddle (with greased rails) and upper cradle assembly (G).
• Grease and assemble the M5 bolt (D) and M5 cradle washer (E), then install the bolt and spacer through the seatpost bolt hole and through the lower cradle (H).
• Grease and install the M5 nut (F) onto the M5 bolt (D).
• Adjust the saddle fore-aft position, then adjust the angle of the saddle by turning the M6 bolt (A).
• With a 4 mm Hex key, torque the M5 bolt (D) to 55 in-lbf / 6.2 Nm, then check the saddle angle. If the angle still needs to be adjusted, loosen the M5 bolt (D), loosen or tighten the M6 bolt (A) accordingly, then torque the M5 bolt again. Repeat until the saddle is at the desired angle.

If using a saddle without a central opening, bolt (A) can be adjusted by inserting a 1.5 mm hex key through the holes on the sides of the bolt head.

TERRA SEATPOST

• Grease the inboard rail clamp contact surfaces (D), then install them in the seatpost head assembly (F).
• Position the saddle rails on the inboard rail clamps.
• Position the outboard rail clamps (C) over the saddle rails. Use 7x7 mm clamps for alloy rails or 7x9 mm clamps for carbon rails.
• Insert the female bolt (E) through one of the outboard rail clamps and key the bolt tab in the outboard rail clamp groove.
• Apply thread-locker to the bolt threads (A) and grease to the bolt head and washer (B), then place the washer on the male bolt.
• Install the male bolt in the opposing outboard rail clamp, then thread it into the female bolt.

SEATPOST CLAMP

• Make sure the seat collar bolt is facing toward the back of the bike.
• If using Shimano Di2, install the battery in the seatpost using the grommet assembly (S186800006), then plug the seat tube wire into the battery.
• Apply carbon assembly compound (fiber paste), then insert the seatpost into the seat tube.
• Grease the seat collar bolt and spacer, then use a 4 mm Hex key to torque the bolt to 55 in-lbf / 6.2 Nm.

SEATPOST MINIMUM/MAXIMUM INSERTION

Both the frame and seatpost have minimum insertion requirements. Additionally, the frame has a maximum insertion limit to prevent damage to the tire cutout area.

• MINIMUM INSERTION: The seatpost must be inserted into the frame deep enough so the minimum insertion/maximum extension (min/max) mark on the seatpost is not visible (A). The frame requires a minimum of 75 mm of insertion (B).
• If the post is at the minimum and the saddle is not at the desired position, the seatpost must be replaced with a longer or shorter seatpost.
• MAXIMUM INSERTION: The seat tube is reamed to a specified maximum insertion depth (C) which varies for each frame size. This ream depth limits the insertion depth of the seatpost. If the post is at the maximum insertion and the saddle is not at the desired position, the seatpost must be replaced with a shorter seatpost.
• Once the saddle height is determined, torque the seat collar bolt to 55 in-lbf / 6.2 Nm.

Do not apply grease to the contact surfaces between the seatpost and the seat tube. Grease reduces friction, which is critical to proper seatpost grip. Specialized recommends the application of carbon assembly compound (fiber paste), which can increase friction between carbon surfaces. Please visit your Specialized Authorized Retailer for additional information.

Failure to follow the seatpost and frame insertion requirements may result in damage to the frame and/or seatpost, which could cause you to lose control and fall.

For general instructions regarding the installation of the seatpost, refer to the appropriate section in the Owner's Manual. Riding with an improperly tightened seatpost can allow the saddle and seatpost to slide down, which can damage the frame and cause you to lose control and fall.

FORK & STEM ASSEMBLY

• Install the front end (fork, headset, headset spacers, stem, handlebar, wheels) on the frame then determine the rider's fit. Do not install more than 35 mm of spacers (A) between the stem and the headset cover.
• Trim the steerer tube so the final cut is 3 mm below the top of the stem (B) (or 3 mm below the top of the spacer (C) if a 5 mm spacer is used).
• Install the steerer tube expander plug into the steerer tube. Using a 6 mm hex bit, torque the plug to 45 in-lbf / 5.1 Nm.
• When installing the headset for the final assembly, grease the bearings and compression ring.
• Install the headset cover, spacers, and stem, followed by the top cap and bolt. Using a 4 mm Hex key, torque the bolt to 44 in-lbf / 5.0 Nm.
• Once the bike is fully assembled, adjust the headset using the front brake to determine if there's any headset looseness.
• The headset cover measures 8.5 mm thick. The maximum spacer stack height between the headset cover and the stem is 35 mm, for a total of 42 mm.
• The maximum combined height of the stem's steerer tube clamp and any spacers placed above the stem (max 5 mm) must not exceed 45 mm.

Make sure to determine the appropriate rider stem height before cutting the steerer tube. Ideally, the steerer tube should be cut 3 mm below the top of the stem. Alternatively, one optional 5 mm solid spacer may be placed above the stem. In that case, the steerer tube should be cut 3 mm below (C) the 5 mm solid spacer.

The stem must be fully supported by the expander plug. Do not place more than one 5mm solid spacer above the stem. In addition, the combined height between the stem and optional 5 mm spacer (from the bottom of the stem to the top cap) must not exceed 45 mm. This is important if the originally equipped stem is changed with an aftermarket one. Exceeding 45 mm or placing more than one 5 mm solid spacer above the stem may cause the stem to crush the steerer tube which may result in serious injury or death.

The bicycle comes with one 5 mm solid spacer and 35 mm of scalloped spacers. Only the solid spacer should be used above the stem. The scalloped spacers should only be used below the stem, i.e., between the stem and the headset cover.

Do not apply grease or carbon assembly compound (carbon paste) between the stem and the steerer tube, and do not twist the stem onto the steerer tube. This can result in damage to the composite surface, which may result in a catastrophic failure of the fork, resulting in serious personal injury or death.

REAR DERAILLEUR HANGER

All bicycle models are UDH (Universal Derailleur Hanger) compatible.

• Install the UDH hanger (A) into the frame dropout and rotate it forward until it's completely seated (B) in the hanger pocket or contacts the rotational stop tab.
  The hanger must be completely seated in the hanger pocket or against the frame stop tab when tightened to the specified torque.
• Install the UDH washer (C), then thread the UDH bolt (D) through the washer and into the hanger.
• Using a reverse torque wrench and 8 mm hex bit, torque the bolt to 25 Nm / 221 in-lbf. The UDH bolt is left-hand threaded.
  
• Apply grease to the rear thru-axle (E) threads, then install the wheel, thru-axle, and conical washer. Using a torque wrench and 6 mm hex bit, torque the thru-axle to 15 Nm / 133 in-lbf.

Before your first ride and regularly thereafter, ensure the thru-axle and UDH are torqued to specification, and that the UDH has not moved. Thru-axles and the UDH can loosen over time depending on the type and frequency of use. This is especially true if they were not installed correctly. Riding with a loose thru-axle or UDH can result in a loss of control of the bicycle and can cause you to fall.

GENERAL NOTES ABOUT MAINTENANCE

The Crux is a high-performance bicycle. All regular maintenance, troubleshooting, repair, and parts replacement must be performed by an Authorized Specialized Retailer. For general information regarding maintenance of your bicycle, please refer to the Owner's Manual. In addition, routinely perform a mechanical safety check before each ride, as described in the Owner's Manual.
ƒGreat care should be taken to not damage carbon fiber or composite material. Any damage may result in a loss of structural integrity, which may result in a catastrophic failure. This damage may or may not be visible in inspection. Before each ride and after any crash, you should carefully inspect your bicycle for any fraying, gouging, scratches through the paint, chipping, bending, or any other signs of damage. Do not ride if your bicycle shows any of these signs. After any crash, and before you ride any further, take your bicycle to an Authorized Specialized Retailer for a complete inspection.
ƒWhile riding, listen for any creaks, as a creak can be a sign of a problem with one or more components. Periodically examine all surfaces in bright sunlight to check for any small hairline cracks or fatigue at stress points, such as welds, seams, holes, and points of contact with other parts. If you hear any creaks, see signs of excessive wear, discover any cracks, no matter how small, or any damage to the bicycle, immediately stop riding the bicycle and have it inspected by your Authorized Specialized Retailer.
ƒLifespan and the type and frequency of maintenance depend on many factors, such as use, rider weight, riding conditions, and impacts.
ƒExposure to harsh elements, especially salty air (such as riding near the ocean or in the winter), can result in galvanic corrosion of components such as the crank spindle and bolts, which can accelerate wear and shorten the lifespan. Dirt can also accelerate wear of surfaces and bearings. The surfaces of the bicycle should be cleaned before each ride. The bicycle should also be maintained regularly by an Authorized Specialized Retailer, which means it should be cleaned, lubricated, and (partially) disassembled and inspected for signs of corrosion and/or cracks. If you notice any signs of corrosion or cracking on the frame or any component, the affected item must be replaced.
ƒRegularly clean and lubricate the drivetrain according to the drivetrain manufacturer's instructions.
ƒDo not use a high-pressure water spray directly on the bearings. Even water from a garden hose can penetrate bearing seals and crank interfaces, which can result in increased bearing and crank wear, which can affect the normal function of the bearings. Use a clean, damp cloth and bicycle cleaning agents for cleaning.
ƒDo not expose the bicycle to prolonged direct sunlight or excessive heat, such as inside a car parked in the sun or near a heat source such as a radiator.

Failure to follow the instructions in this section may result in damage to the components on your bicycle and will void your warranty, but, most importantly, may result in serious personal injury or death. If your bicycle exhibits any signs of damage, do not use it and immediately bring it to your Authorized Specialized Retailer for inspection.
