For riders who need a thru axle that is lighter, stronger, or simply unavailable in a standard size, a custom titanium thru axle can be an ideal solution.
At S-PARTS, we can manufacture custom front and rear titanium thru axles based on the exact dimensions of your original axle. This is especially useful for bikes with non-standard axle lengths, unique thread pitches, special derailleur hanger systems, or discontinued OEM hardware.
Why Choose a Custom Titanium Thru Axle?
Standard aftermarket thru axles are not always compatible with every frame.
Even if two bikes both use a 12×100 mm front or 12×142 mm rear axle standard, the actual axle can still differ in:
-
Effective axle length
-
Thread pitch
-
Thread length
-
Axle head diameter
-
Axle head thickness
-
Flat or tapered head design
-
Derailleur hanger configuration
A difference of only a few millimeters can affect fitment.
That is why our custom thru axles are manufactured according to the measurements of your original axle rather than relying only on the bike model.
TC4 Titanium Construction
Our custom thru axles are manufactured from high-strength titanium alloy, offering an excellent balance of:
-
Low weight
-
High strength
-
Corrosion resistance
-
Long-term durability
-
Premium metallic appearance
Compared with many original steel or aluminum axles, titanium provides a high-end upgrade for lightweight road, gravel, and performance bicycles.
Custom Front and Rear Specifications
Each axle can be manufactured according to your original dimensions.
For accurate production, we normally require the following information.
Front Thru Axle
-
Diameter: M12 or other specification
-
Effective length, excluding the axle head
-
Thread pitch
-
Thread length
-
Axle head diameter
-
Axle head thickness
-
Flat-head or tapered-head design
Rear Thru Axle
-
Diameter
-
Effective length
-
Thread pitch
-
Thread length
-
Axle head diameter
-
Axle head thickness
-
Flat-head or tapered-head design
-
Derailleur hanger type, if applicable
For some modern bikes using systems such as SRAM XPLR, UDH, or proprietary derailleur hangers, the rear axle specification is especially important.
Example Custom Specification
A typical custom pair may look like this:
Front
-
M12
-
Effective Length: 127.25 mm
-
Thread Length: 16 mm
-
Thread Pitch: P1.5
-
Flat Head
Rear
-
M12
-
Effective Length: 166 mm
-
Thread Length: 20 mm
-
Thread Pitch: P1.0
-
Flat Head
-
Compatible with SRAM Force XPLR derailleur hanger
Depending on dimensions and construction, a custom titanium front and rear axle pair can weigh approximately 38g per pair.
Actual weight will vary according to the required dimensions.
Custom Colors Available
In addition to natural titanium, selected custom thru axles can also be finished in different colors.
For example:
-
Natural Titanium
-
Gold
-
Black
-
Blue
-
Purple
-
Other finishes depending on availability
Because machining and coloring may be completed at different production facilities, custom colored versions generally require additional production time.
Production Time
The typical production time for a custom titanium thru axle set is approximately:
10–15 business days
This may vary depending on:
-
Axle dimensions
-
Machining complexity
-
Surface finishing
-
Coloring requirements
-
Factory workload
Since these products are made specifically according to the customer's measurements, we strongly recommend confirming every dimension before production begins.
How to Measure Your Original Thru Axle
For the most accurate result, we recommend using a digital caliper.
Please measure:
-
Effective Length
Measure from the underside of the axle head to the end of the axle body. -
Thread Diameter
Usually M12 on modern road and gravel bikes. -
Thread Pitch
Common examples include P1.0, P1.5, and P1.75. -
Thread Length
Measure only the threaded section. -
Axle Head Diameter
-
Axle Head Thickness
-
Head Design
Confirm whether the original axle uses a flat head or tapered/conical head.
We also recommend sending clear photos of the original axle together with the measurements.
Who Is This Service For?
Custom titanium thru axles are particularly useful for:
-
Frames with unusual OEM axle dimensions
-
Older bikes with discontinued replacement parts
-
Lightweight road bike builds
-
Gravel bikes
-
Custom bicycle projects
-
Riders using special derailleur hanger systems
-
Riders who want matching titanium hardware
-
Customers who cannot find a compatible aftermarket axle
Important Compatibility Note
Do not determine compatibility based only on the bike's hub spacing.
For example, two bikes may both use a 12×142 mm rear axle but have completely different:
-
Axle lengths
-
Thread pitches
-
Thread lengths
-
Head designs
Before ordering, always verify your original axle dimensions.
