Intense Primer Shock Size: 2026 Dimensions and Hardware
Intense Primer shock size is 210×55 mm for the 2026 frame, with 8×20 mm mounting hardware at both ends. The manufacturer repeats those dimensions in its frame table and FAQ. They are the starting specifications for identifying a replacement, rather than a guarantee that any shock carrying the same dimensions is suitable.
Intense Primer shock size and mounting details
The frame specification labels the shock itself separately from the front and rear mounting hardware. Preserve all three entries when discussing a replacement: 210×55 mm shock, 8×20 mm front hardware and 8×20 mm rear hardware. A listing that supplies only the headline shock size leaves the mounting details unanswered.
The same frame table gives maximum rear travel as 150 mm. Rear-wheel travel and the shock’s 55 mm stroke are different measurements; do not replace one with the other in an enquiry. Likewise, the dimensions printed for this 2026 frame should not be assumed to describe an older Primer, even when a seller uses the same model-family name.
Compare the named frame-first shock choices
The current official frame-first build page describes a RockShox Super Deluxe Ultimate D1 and a Fox Float X Factory option. Both entries specify 210×55 mm and 8×20 mm hardware at each end, and both are described as custom tuned. This supports those named offerings on the page; it does not establish that every retail version has the same tune.
RockShox’s entry lists high- and low-speed compression adjustment, low-speed rebound and an Open/Threshold control. The Fox entry lists low-speed compression, rebound and a two-position adjustment. These are the controls recorded by Intense, not riding-test results. Consider which adjustments you understand and will use, while having the supplier confirm the exact frame-specific unit.
Ask about the complete replacement
Give the supplier the model year, frame identification, current shock details and all three mounting specifications. Ask whether the proposed unit is the appropriate custom configuration and includes the correct hardware. Matching dimensions does not answer questions about reservoir clearance, tuning or the complete installation. This guide does not supply an unverified air pressure or sag target.
The manual asks owners to follow recommended travel limits and directs component work to the relevant manufacturer’s instructions where it is not covered. Keep installation and servicing with those instructions and qualified support. If a used bicycle’s year or installed shock cannot be established, resolve that identity before treating the 2026 measurements as its replacement specification.
The Intense collection of guides and model-family introduction explain the broader range. A shock enquiry should remain tied to the exact Primer frame rather than another Intense suspension platform.
