All custom Ti Cycles racks -- titanium or steel -- are built by hand in our Portland shop and made to order for each individual customer.

Before placing your order, please take a moment to understand the information required for custom rack construction

To streamline the ordering process and to ensure a proper fit with your frame, we accept orders for custom racks built with dimensional data obtained through one of the following processes:

OPTION #1 -- Build on the Frame
The preferred method of construction and the only way Ti Cycles Fabrication can reliably build a custom rack with accurately placed mounting points is to have the bicycle frame and/or fork in our shop during construction. 

PLEASE NOTE: A technical drawing of your frame will likely not translate to the actual physical construction with the degree of accuracy required for the construction of hard mounted (non-adjustable) racks. Because of the geometry differences inherent in frame designs of different sizes braze-ons and bosses such as rack mounts are not able to be universally located with a rigid fabrication fixture. These mounting points are generally added to a frame individually, at the end of the construction process, using an adjustable fixture that does not lend itself to repetitive accuracy. If the actual physical mounting point locations on the frame differ from the locations detailed in the frame drawing by just a few millimeters it is unlikely that a hard mounted (non-adjustable) rack will fit properly.

OPTION #2 -- Build an Adjustable Rack
Racks built without the bicycle frame and fork on site cannot be verified for accuracy when mounted. To ensure a wide range of frame compatibility it is recommended that racks built without the frame and fork on site use adjustable upper struts, as shown below.

 
 

OPTION #3 -- Build From a Template
For ordering a fixed rack without having the bike on site, it is possible for a qualified 3rd party with responsibility for accuracy to make a template with rigid, flat cardboard or similar density panel to build an approximately fit rack off of.
--- Template material must have at least one perfectly square corner or 90° angle marking for a reference point.
--- Tools for measuring angles and marking lines will be helpful. A bubble level, a carpenter's square, and a metal straight edge are recommended.
--- The bicycle must be secured in place upright, on a level surface, with both wheels straight, vertically perpendicular to the floor.
--- Ti Cycles assumes no responsibility for the accuracy of your template. 



REAR RACK TEMPLATES

1) MARK LOWER MOUNTING POINT -- Make a small hole to locate the lower rack mounting point. This is the load bearing mounting point located near the rear axle.

Thread a long bolt into the lower rack mounting point.

Place the hole in the cardboard over the bolt in the lower rack mounting point.


 

SQUARE UP YOUR TEMPLATE -- Align your straight edge or reference line vertically and #1 parallel to the bicycle center line and #2 level with the floor. Secure or prop the material to stay in position.

At every point in the process check and re-check that the template material is level, square, and straight with the frame.

 

2) MARK UPPER MOUNTING POINT -- For split stays, secure a thin, rigid, and straight piece of material across the eyelet center line.

NOTE: Because upper rack mounts are generally not square with the frame center line, using a long bolt threaded into the eyelet will give an incorrect position.

NOTE: To locate the actual mounting point on split stays it is imperative to account for the offset between the marker line and the eyelet center.

For monostay or "wishbone" configurations simply place your thin, rigid, and straight piece of material through both eyelets.

With the template square and straight with the frame and any offset compensated for, mark the upper mounting point with a hole.

 

3) VERIFY THE TEMPLATE IS SQUARE --The template material should line up with pins placed in both mounting locations.

The template material must line up with the mounting points and still be level, square, and straight with the frame. If it is not, start over.

 

4) MARK TIRE AND DECK HEIGHT -- With the template material in place, use a level to mark the location of the top of the tire.

Reference the tire height mark to make a straight line for the desired deck height. The bottom of the rack deck should be a minimum of 20mm above the tire height line to allow for clearance of mud and debris.

NOTE: With the compact geometries found on most modern frames and/or smaller frame sizes it is normal for the rack deck to sit above the upper mounting point.


5) DRAW OUT THE RACK PROFILE -- Double check to make sure the mounting points, tire height, and deck height marked on side 1 are accurate for side 2 when mirrored.

Sketch the side view of your rack and be sure to include, either by drawing or notation, any details such as pannier bars, light mounts, etc.

 

6) MAKE IT 3D -- To tie the two sides of the rack together we will need a width measurement, taken from OUTSIDE TO OUTSIDE of the rack mounting points. This dimension is required for BOTH LOWER AND UPPER MOUNTING POINTS.

 
 


FRONT RACK TEMPLATES

1) MARK LOWER FORK MOUNTING POINT -- Follow the same steps as above using the fork leg mounting points to reference the rest of your rack. Always be sure to use the center of the eyelet when locating mounting points, and to measure the distance between the Left and Right mounting points.

Check, double check, and check a third time that your template and bike are square, level, and straight.

 

2) MARK FORK CROWN MOUNTING POINT -- Forks with two upper mounting points can be located using the same process as for rear racks. For single center mounting points, use a square to mark your template.

Use the location of the upper mounting point to mark the height of the rack deck. Forks with two upper mounting points must also locate the tire height and be sure to mark the deck height a minimum of 20mm above the tire.

 

3) DRAW OUT THE RACK PROFILE -- Confirm that the mounting points line up on the opposite side of the fork and then sketch out the rack side view, making sure to include any details such as pannier bars, light mounts, etc. Also be sure to measure the width of the rack, taken from OUTSIDE TO OUTSIDE of the rack mounting points. This dimension is required for BOTH LOWER AND UPPER MOUNTING POINTS.

 
 

Send the unfolded cardboard original or a transposed paper copy at 1:1 scale to our shop along with any notes or detailed drawings. Racks constructed from templates are only as accurate as the templates they are built from. Ti Cycles assumes no responsibility for the accuracy of racks built from 3rd party templates. 

For complete accuracy we strongly encourage you to send us your frame and/or fork to template the rack off of.
