Unpacking and Assembling Your Diamondback Road Bike


Begin by carefully opening the box. Be aware of the sharp staples that may have been used to secure the box and be mindful not to cut yourself on them. For assembly you will need: cutters/scissors; #2 Philips head screwdriver; a 4,5,6mm allen keys.

If, for any reason, you do not have the proper tools or are not confident to safely assemble the bike yourself, it is recommended that you take your bike to a local bike shop for assistance or to have them assemble it. We recommend taking all bikes in for a safety check before riding. They may charge you a fee to do any of these services.

Any damage caused by improper assembly is not considered a manufacturer defect and will not be covered under warranty.


Once you have the bike box opened:

  1. Remove the saddle and seatpost.
  2. Remove the small parts box.
  3. Remove the bike.

Before proceeding, be sure that all parts and material are now removed from the box.

Now that your bike is out of the box:

  1. Detach the wheel by cutting all zipties
  2. Detach handlebar by cutting all zipties that may be holding parts together. Be very careful not to cut any of the bikes shifter or brake cables while doing so
  3. Begin removing all of the packing material from the frame.

Install the seat post and seat.

  1. Loosen the seat clamp and insert the seatpost into the seat tube. If you have bike grease you can apply a small amount to the seatpost before inserting it. For bikes with a Carbon seatpost use the supplied “Carbon Paste” contained in the small parts box.
  2. Make sure that you have inserted the post past the minimum insertion/maximum extension line (printed on post near bottom).
  3. Finish by using the correct hex wrench to tighten. DO NOT OVERTIGHTENESPECIALLY ON CARBON PRODUCTS. NOTE: seat clamp bolts are typically tightened to a MAX of 5nm and noted on seat clamp.

When the bike is fully assembled you will then be able to fine tune the saddle adjustment based on your height. Refer to the Saddle Position section on page 12 of the DB Owner’s Manual for guidance.

Position your bike in a comfortable working position. If you have a bike stand, that’s your best bet.


It’s now time to install your handlebar to the stem. Begin by making sure the cables are in the correct position – cables are not twisted or kinked and the shifter and brake lever on the right (when sitting on the bike) will control the rear of the bike while the shifter and brake lever on the left (when sitting on the bike) will control the front of the bike.

  1. Next remove the stem bolts and face plate. Place the bar in the stem and loosely re-secure the faceplate to the stem. Be sure that your cable routing is suitable and that there are no harsh bends or kinks in the cable.

Once the handlebar is loosely placed in the stem, make sure that it is positioned symmetrically before tightening the faceplate bolts. Most bars will offer some guidance using painted marks on the bar.


When tightening the bolts, tighten them alternately (Use an “X” pattern for four bolt stems) to ensure that the faceplate is equally tight on every side.


The gap opening between the faceplate and the stem should be equal both on the top and on the bottom. DO NOT OVERTIGHTENESPECIALLY ON CARBON PRODUCTS. NOTE: stem bolts are typically tightened to 4nm. Refer to stem manufacturers marking on stem.


Now that your handlebars and seatpost are securely fastened, it’s time to get your front wheel ready for installation. Start by pulling the plastic protective caps off of the axle.


Now install skewer through the axle of the front wheel.

  1. Remove the non-lever side of skewer, as well as one spring, and proceed to insert through the front wheel axle.
  2. Put the spring back on the skewer. Note the correct positioning of the springs on the skewer when mounting (smaller part of spring points in towards hub and spokes).
  3. Thread the skewer nut back on a few turns.

Mount the front wheel on the fork:

  1. Insert wheel into front fork. Make sure wheel is centered in fork.
  2. Once wheel is in the fork tighten the skewer nut until it touches the fork lightly. The quick release part of the skewer should be on the non-drive, left (when sitting on the bike) side.

    1. Then start to close the skewer lever. The QR lever should close with some resistance, but not too much that it is hard to close or open.
    2. When closed, make sure that the QR lever is tucked up to avoid snags.
    3. Most levers are stamped with “close” to indicate quick release is closed.

Once the wheel is in and secure, it’s now time to mount the front brake caliper to the fork.

  1. Start by unscrewing the recessed brake bolt from the bolt on the caliper.
  2. Insert the caliper bolt through the front of the fork crown.
  3. Thread the recessed brake bolt through the back, securing the caliper.
  4. The caliper brake pads should be approximately spaced evenly on both sides of the wheel.

Connect the front Brake Cable:

  1. Run the front brake cable through the barrel adjuster and seat the cable into the barrel adjuster.
  2. Feed the cable through the caliper cable anchor bolt.
  3. To set brake, open cable quick release lever.
  4. Squeeze caliper arms together while pulling down on the cable. Keep pressure on caliper arms and tighten the cable anchor bolt.

Your brake pads may need adjusting once brake is assembled.

  1. Grasp brake pad with one hand and loosen brake pad bolt.
  2. Align pad to be parallel with rim surface and retighten brake bolt. You do not want the pad to come into contact with the tire.
  3. Check to make sure pad is hitting squarely in center of rim braking surface by squeezing the brake lever.
  • 15a
  • 15b
  • 15c

Close the quick release lever on the brake caliper. Squeeze the brake lever as far as you can to the bar to “stretch” the cable.


Once your front brake cable is properly adjusted, cut excess cable off leaving approximately 1.5" of cable. Install cable end cap and crimp cable end cap to avoid the cable from fraying.


For pedal installation, your pedals will show what side they are meant to go on with an “L” or “R” on the end of the spindle or axle (depending on the pedal). We recommend applying a small amount of grease to the threads of each pedal before installing.


Start by hand threading in the left (this should be indicated by an L on either the end of the pedal spindle or pedal axle), non-drive side pedal (when seated on the bike) into the left/non-drive crank arm. Tighten by turning your 15mm to the left (counter clockwise).


Take the right pedal (this should be indicated by an R on the pedal which can be seen on the end of the spindle or on the axle depending on the pedal) and thread into the drive side crank arm (right side when facing forward on bike). Tighten by turning your 15mm pedal wrench to the right (clockwise).

Do not force a pedal that will not thread on easily or you can cross thread the crank arm which will result in a damaged product. Damage caused by improper pedal installation will not be covered under warranty.


Now it is time to make sure the front and rear derailleurs are set properly. While pedaling bike, shift rear derailleur to lowest gear (largest cog) in the rear.


Make sure that low adjustment screw (“L” stamped on Derailleur) is set to ensure it hits the stop and the derailleur cannot shift past the lowest gear (largest cog) and into the spokes of the rear wheel.

  1. Incorrect Chain line
  2. Correct chain line
  • 22
  • 22a
  • 22b

While pedaling the bike, shift the rear derailleur to highest gear (smallest cog) in the rear.


Check the adjustment of the high limit screw (“H” stamped on the rear derailleur) to ensure the derailleur cannot shift the chain past the high gear (smallest cog) and into the frame.

  1. Incorrect Chain line
  2. Correct chain line

For proper rear derailleur alignment refer to the manufacturer’s instructions for your specific derailleur model. Shimano the derailleur jockey wheels should line up directly below smallest cog. On SRAM, the jockey wheel should line up just to the right of the smallest cog. For more information on rear derailleur adjustments please follow the link below.

Now it’s time to make sure the rear derailleur will shift appropriately up and down the rear cog set. Proper shifting is all related to cable tension. Begin by pedaling bike with the chain in the highest gear (smallest cog). Each “click” of the shifter lever should correspond to the chain moving up the gears one cog at a time. To adjust the cable’s tension, use the adjusting barrel at the derailleur/or at the shifter to tune the shifting. If the chain shifts past the desired gear, the cable tension is too high. Turn the adjusting barrel clockwise to ease cable tension. If chain is not shifting to desired gear, turn adjusting barrel counterclockwise to increase tension on cable until chain shifts to desired gear.


Rear Derailleur


Next, adjust the front derailleur. Check to make sure front derailleur height and alignment is correct.

  1. Set derailleur angle so outside plate lines up with large chain ring. Make sure the chain is sitting on the smallest chainring (if there are only two) or the middle chainring (if there are three).
  2. Check height of derailleur using guide sticker on derailleur. If there is not a guide sticker, the outside front derailleur plate should sit about 2mm above larger chain ring on crank.

  • 26b

Now it’s time to set front derailleur adjustment screws. To start this step, shift the rear derailleur so that the bike is in its lowest (largest) cog in the back. Make sure the front derailleur is set so that the chain is in the lowest gear (smallest cog) in the front.

  1. Check the distance of chain to inner plate of front derailleur
  2. Set front Low set screw so that inner plate is approx.. 1-2mm from chain. (“L” stamped on Derailleur)

Next, shift the rear derailleur so that the bike is in its highest gear (smallest cog) in the back and the shift the front derailleur into the high gear (largest chainring).

  1. Check the distance of chain to outer plate of front derailleur
  2. Set the high limit Screw so that the outer front derailleur plate is approximately 1-2mm from chain. (“H” stamped on derailleur)

Align your bars to the front wheel.


Tighten stem cap bolt.


While handlebars are still aligned with the front wheel tighten stem bolts. Most stems have a 4nm maximum torque setting.


Now it’s time to inflate your tires. Each tire will have a recommended air pressure (measured in PSI) on the sidewall. Please follow the recommended inflation setting.


Last step is to go through the entire bike one more time to make sure that:

  1. every bolt is tight
  2. that your wheels are secured in place, so that your front and rear brakes are functioning properly
  3. that the handle bars are tight and don’t move when you hold the front wheel between your legs and twist them.

If, for any reason, you do not have the proper tools or are not confident to safely assemble the bike yourself, it is recommended that you take your bike to a local bike shop for assistance or to have them assemble it. We recommend taking all bikes in for a safety check before riding. They may charge you a fee to do any of these services. Any damage caused by improper assembly is not considered a manufacturer defect and will not be covered under warranty.
