SPECT 空力公式 Mira frameset. The retained CNY 6,999 observation matches the China Cycle launch price for the Mira frame, fork and integrated-cockpit package; the pictured show build is not treated as a standard complete bike.
The displayed Est. ¥12,999 estimate adds the adjustable ¥6,000 build allowance to the recorded ¥6,999 frame price.

- Frame weight basis
- Upper end of the 900–940 g quoted launch range; size, finish, hardware inclusion and weighing method are not stated, and no delivered production frame has been independently weighed
- Bottom bracket
- T47×86 threaded
- Cockpit
- Matching integrated cockpit included in the reported launch package
- Drivetrain_compatibility
- Electronic shifting only; no drivetrain is included with the frameset package
- Stiffness evidence
- Independent launch reporting says SPECT judged the development Mira frame too stiff and was softening the lay-up before delivery; this is exact development-state evidence, not a numeric or delivered-production-frame test
The CNY 6,999 evidence is for the frame, fork and matching-handlebar package. The show bike is illustrative. The 32C current-retailer limit conflicts with independent launch reporting of 35 mm rear / 38 mm front fit, so the catalog preserves maximum clearance as unknown rather than selecting one claim.
Buying context
Before buying, verify Production-revision maximum tire clearance: current exact sources conflict between 32C and 35 mm rear / 38 mm front claims; Delivered-frame weight and stiffness verification for a frozen production revision; Current mainland stock, final checkout conditions and domestic warranty route.
About SPECT
Current China Cycle and regional distributor evidence consistently identifies the cycling brand as SPECT / 空力公式. The evidence does not establish a mainland legal entity, manufacturing ownership or factory relationship.
Price record and sources
These sources support this model page; individual claims retain the confidence of their cited source.
42 screenshots and 160 listing observations were normalized into 133 model groups. Listed, coupon, subsidy, and first-order conditions are preserved in the research ledger. Screenshots, purchase source identities, and private data are not redistributed.
Current China Cycle coverage identifies SPECT / 空力公式 Mira as an aero road frameset and states that the frame, fork and matching handlebar package was introduced at CNY 6,999. The show bike is not treated as a standard complete build.
Current exact-model retailer page identifies a frame, fork, seatpost and integrated-cockpit package; states T1100 + M90 carbon, T47x86, electronic-only shifting compatibility and 25C-32C tire support. Its 32C limit conflicts with wider launch reporting and is not recorded as a verified maximum.
Regional distributor page identifies SPECT / 空力公式 Mira, T1100 + M90 carbon, T47x86, UDH, electronic-only shifting compatibility and the included 55 mm-rise integrated cockpit. Marketing stiffness claims are not treated as controlled measurements.
Independent launch assessment reports a quoted 900-940 g Mira frame, T1100 + M90 lay-up and unresolved geometry/delivery changes. It reports 35 mm rear and 38 mm front fit, conflicting with the retailer's 32C claim. It also reports that SPECT called its development frame too stiff and was re-tuning the lay-up; no numeric or delivered-frame test exists.
Independent geometry database preserves a 2026 Mira size table. Launch reporting says the geometry changed repeatedly, so no geometry values are promoted into the candidate until the production revision is frozen.
