Verify that the fork, headset and all required parts for proper assembly have compatible dimensions. The fork,
headset, headset spacers and stem steerer clamp must have compatible diameters. Use of incompatible components
can cause component failure.

•Make sure headset and stem parts that come into contact with the steerer tube are free of burrs or sharp edges.
Remove burrs or sharp edges by using very fine grit sandpaper.

Installation
1. Once the headset cups have been installed into the frame according to the headset manufacturer’s instructions,install the crown race. Holding the fork in one hand, install the headset’s fork crown race onto the fork race seatwith a headset crown race setting tool and hammer.
WARNING: Do not rest the fork dropouts on the floor or other hard surface; doing so can damage the fork, making
it unsafe to ride.
2. Install the bottom assembly of the headset according to the manufacturer’s instructions and insert the fork into theheadtube. Install the top assembly of the headset according to the manufacturer’s instructions.
3. Install the stem on the steerer and slide it down to seat it firmly against the spacers on the top of the heasdset.
Gently tighten the stem’s steerer clamp bolt(s) just enough to hold the assembly in place.

4. Mark the steerer tube at the top edge of the stem. Remove the stem and spacers from the steerer and the fork fromthe bike. Mark the steerer again, this time 3mm below the first mark. This will be your cutting mark.
WARNING: Do not modify the fork, other than cutting the steerer tube to the correct length for your bicycle.
Modifying the fork could cause fork or other component failure resulting in serious injury.
5. To ensure a square cut, the use of a steerer tube cutting guide is strongly recommended. Using a hacksaw with a finetoothed metal cutting blade, begin cutting the steerer at the cutting mark­—the use of cutting fluid is recommended.
Once cut, use a file to remove any burrs on the inside and outside edges of the steerer tube.
6. Install the star nut supplied with the headset into the steerer tube per the manufacturer’s instructions.
7. Reinstall the fork, headset assemblies, spacers, and stem, and pre-load the top cap to attain the proper headset
adjustment in accordance with the headset manufacturer’s instructions. Tighten the stem’s steerer clamp bolt(s)to the stem manufacturer’s specifications.
8. Attach the front wheel to the fork, and align the stem with the front wheel. Tighten the stem’s steerer clamp bolts
to the stem manufacturer’s specifications. While straddling the toptube and holding the front wheel between your legs,
make a strong attempt to rotate the stem around the steerer. If the stem rotates, increase the torque on the steerer
clamp bolts; do not exceed 7Nm.
WARNING: Alignment of the front wheel assembly should not be less than 6mm clearance between the tire, frame,fork, or fender and its attachment bolts. Inadequate tire clearance can result in serious injury.
9. Follow the wheel manufacturer’s instructions for correct clamping of the wheel quick release and install the front wheel.
WARNING: Failure to properly adjust the quick release and secure the wheel can result in serious injury.
10. Install and adjust handlebar to stem following stem and handlebar manufacturer’s instructions.
WARNING: Failure to properly install and adjust handlebar and stem can result in serious injury.
11. Install and adjust the front brake following the brake manufacturer’s instructions.
WARNING: Failure to properly install and adjust brakes can result in serious injury.
12. Check the tightness of the stem bolts before each ride, and inspect the fork for damage before every ride.
WARNING: Attaching incompatible clamping devices to a fork can lead to breakage, causing a loss of control.
If you are not sure if a device is compatible, consult your dealer.
WARNING: Do not modify the fork, other than cutting the steerer tube to the correct length for your bicycle. Modifying thefork could cause fork or other component failure resulting in serious injury.
•Attaching incompatible clamping devices to a fork can lead to breakage, causing a loss of control. If you are not sureif a device is compatible, consult your dealer•

This fork is only compatible with quick release fenders. Consult fender manufacturer for specific compatibility•

Do not mount racks or any other load bearing accessory to the fender mounts. Doing so could result in fork breakage,causing a loss of control•Entanglement of an object in your wheel could stop the rotation of the wheel causing a loss of control or crash that could
lead to serious injury. Always secure all cargo, luggage, and any mounting straps. Avoid running over objects in the roador trail including sticks or debris•

Always check for adequate clearance between the front wheel and any accessory mounted to the fork•

Every bicycle product has a finite useful life. A bicycle and its components such as forks are subject to wear andstress. Different materials and mechanisms wear or fatigue from stress at different rates and have different life cycles.
If a component’s life cycle is exceeded, the component can suddenly and catastrophically fail, causing serious injury
to the rider. This is why you need to frequently inspect your bicycle and its components for any signs of wear or fatigue.
Scratches, cracks, bending, fraying or discoloration are all signs of stress-caused fatigue and may indicate that a partis at the end of its useful life and needs to be replaced. When you see any signs of fatigue or damage, do not ride thebicycle. Take it to a dealer for inspection, repair or replacement as necessary•

While the materials and workmanship of your bicycle, bicycle fork or of individual components may be coveredby a warranty for a specified period of time, this is no guarantee that the product will last the term of the warranty.
Product life is often related to the kind of riding you do and to the treatment to which you submit the bicycle.
The warranty is not meant to suggest that the bicycle or component cannot be broken or will last forever. It onlymeans that the product is covered subject to the terms of the warranty

Ongoing Maintenance
Loosen the stem’s steerer clamp bolts before making any stem-to-fork alignment adjustments.
Periodically remove, clean and inspect your fork for damage, cracks or any other damage. Any questions about marks
or cracks on the fork should be directed to your Surly dealer immediately.
Regularly inspect all components for any damage (cracks, chips, etc.) and replace components upon detection.
In the event of a crash or impact, carefully inspect handlebars, fork, stem, seatpost, wheels and the frame for any visible
damage. As with any component under varying degrees of stress there is a fatigue life that is proportional to the typeof use and abuse applied to the part. Always inspect your components before a ride. If you have doubts about the integrity
and condition of any part, replace it. Consult your dealer if you are unsure about the condition of your Surly fork or any
part of your bicycle.
