Breezer Thunder Fork: Bomber Z2 Travel, Offset and Axle Details
The Breezer Thunder fork is listed as a Marzocchi Bomber Z2 with 130 mm travel, 44 mm offset and a 15 × 110 Kabolt axle. Those three measurements answer different questions. Keep them separate when identifying the bicycle’s front end or discussing a possible replacement.

Three Breezer Thunder fork entries to distinguish
Travel describes the fork’s listed suspension movement. Offset is a different geometric dimension, and the axle entry describes the front attachment standard. A fork matching only the 130 mm travel figure has not therefore been shown to match the rest of the documented assembly.
The same equipment table names a Rail damper and rebound adjustment. It does not provide the rider-specific air pressure, click settings or service interval needed to set up a particular fork. Those questions belong with the instructions for the actual installed component, rather than a setting borrowed from another Thunder owner.
Keep the front and rear dimensions apart
The frame has a tapered head tube described as 1-1/8 to 1-1/2 inches. The fork’s 15 × 110 entry concerns the front wheel, whereas the frame’s 148 mm spacing concerns the rear. Mixing these labels can produce an apparently detailed parts enquiry that still names the wrong end of the bicycle.
Why an older fork photograph can mislead
The pictured ThunderPRO was photographed in 2009 and carries a photo title identifying 2010. Its visible suspension fork establishes the broad layout of that older bicycle. It cannot establish the old fork’s travel, axle thread, offset or compatibility with a present frame.
The listing identifies the bike as the Breezer Thunder in Heavy Skies. See the Breezer Thunder Bike — Heavy Skies listing alongside those details. Match the intended bicycle to this named listing before treating the current manufacturer’s fork table as relevant. Neither the catalogue identity nor the old photograph certifies that a replacement fork will work on another generation.
Prepare a useful component discussion
Bring the actual bicycle identity and the existing fork’s identifying details to the conversation. The manufacturer record supplies a starting point—Bomber Z2, 130 mm, 44 mm, Kabolt 15 × 110—but not all the dimensions or installation conditions of a proposed substitute. No torque or axle thread is specified in this record.
Breezer’s linked general owner manual directs readers to component manufacturers for through-axle operation and suspension setup. Its broad suspension examples are not a verified pressure prescription for this particular Z2. A bicycle that has been modified also needs its installed equipment identified, even when the frame still bears the original name.
FAQ
Does 130 mm identify a complete replacement fork?
No. Travel alone does not establish the remaining fit or installation requirements.
Is 148 mm the listed front axle spacing?
No. It is the frame’s rear-spacing entry; the fork lists 15 × 110.
Can the historical photo supply a setup pressure?
No. It neither identifies the current fork nor measures its settings.
For context on the range’s different bicycle types, consult the brand introduction. Start a broader model enquiry from the Breezer directory once the actual fork and frame are identified.
