Bombtrack Hook Axles: Dimensions, Threads and Spare-Part Codes
Bombtrack Hook axles are recorded with dimensions, thread pitch and separate front and rear part codes. The saved specification gives 12 × 100 mm at the front and 12 × 142 mm at the rear, both with a 1.5 thread-pitch entry. The accompanying spare-parts list makes this more specific than an enquiry based on hub spacing alone.
Bombtrack Hook axles have position-specific codes
The front through-axle reference is BT-TA-F-601, while the rear is BT-TA-R-602. Preserve the full code and position when discussing a missing or damaged part. The front and rear dimensions describe different locations, so a shared twelve-millimetre diameter does not make the assemblies equivalent.
The 100 and 142 mm interface labels are not stated overall axle lengths. The source adds thread pitch but does not provide every shoulder, threaded-section or total-length dimension. Supplying the named code to a dealer is more precise than constructing an assumed replacement length from those interface figures.
Axles, end caps and cassette bodies are different parts
The spare list also names BT-HC-014 front hub end caps, BT-HC-017 rear end caps and BT-CB-006 for the cassette body. These identifiers concern wheel components rather than alternative names for the two through-axles. Establish which piece is actually needed before asking a supplier to match a code.
The wheel rows identify sealed Bombtrack Tau hubs, six-bolt disc attachment and an eleven-speed HG body at the rear. The complete drivetrain nevertheless lists a ten-speed cassette. Keep both descriptions in the record; the body’s label is not a claim that the installed cassette has eleven sprockets.
Make the replacement request specific enough to answer
The catalogue listing is Bombtrack Hook Bike — Metallic Black. Pair that model identity with front or rear position, the actual part markings and any known wheel changes. Ask which documented reference applies to the frame, fork and wheel presently being discussed.
A code copied from this saved page is not a cross-generation compatibility guarantee. The historical Hook 2 MY19 photograph does not establish that its small parts use these references. Nor does this guide supply tightening torque or instructions for securing a wheel.
The Bombtrack introduction describes the range’s development, and the model topic groups other equipment questions. For this task, keeping the part’s identity and location attached to its complete reference prevents an end-cap request from becoming an axle order.
FAQ
Which reference belongs to the front through-axle?
The saved spare-parts list names BT-TA-F-601 for the front.
Does 142 mm specify the rear axle’s total length?
No. It is an interface entry, without a complete overall-length specification.
Does an eleven-speed HG body mean the listed cassette is eleven-speed?
No. This complete build separately lists a ten-speed cassette.
