Apollo Scout 30 2021: Read the Carbon Gravel Build
The Apollo Scout 30 in the Australian manufacturer's 2021 catalogue is a carbon gravel bicycle with a 700C, two-by-eleven-speed headline. Its detailed table is useful for identifying an older example, especially when a short advertisement says only Scout. Treat this as a guide to that printed build, rather than a current sales specification or a verdict from riding the bicycle.
Apollo Scout 30: start with frame and fork
The frame entry describes a carbon monocoque gravel frame with a BB86 press-fit system and a tapered head tube. The fork is also carbon, with flat-mount disc provision and a listed 12 mm through axle. Carbon in both rows is different from a bicycle whose material description refers only to its fork.
A used bike should be matched through its documentation and actual equipment, not its colour alone. The table identifies medium, large and extra-large codes for the same finish. That code list does not establish the present condition of a frame or confirm that its original fork remains fitted.
Keep the printed transmission entries intact
The crankset row names Shimano GRX FC-RX810 with 48/31-tooth rings, while the cassette row names CS-M8000 with an 11–40 range. The rear-derailleur entry separately says RD-RX812. Preserve all those entries alongside the two-by-eleven headline; this catalogue reading does not resolve component compatibility or approve a replacement combination.
For a parts enquiry, give the mechanic the fitted controls, crank, derailleur and cassette identities. A GRX label on one item cannot stand for every component. Original catalogue information and a later owner's substitutions can both be relevant, so record differences rather than assuming the whole transmission is unchanged.
Read the wheel and contact-point details
The listed tyres are Veetire G-Sport 700c × 40c, paired with DT Swiss R-500-Disc rims. Forty millimetres describes the fitted nominal tyre entry, not a stated maximum clearance or a mudguard allowance. The hydraulic GRX brake row lists 160 mm rotors; it does not establish a maximum rotor upgrade.
Component lengths also vary: the medium has a 172.5 mm crank entry, while large and extra-large list 175 mm. The bars are 42 cm on medium and 44 cm on the larger sizes. Use these as questions for an actual fitting, not a universal rider-height chart. The Australian Apollo introduction supplies broader context; the Apollo topic keeps these model-specific records together.
FAQ
Is 40c a verified maximum tyre clearance?
No. It is the nominal size of the tyre listed in this particular catalogue build.
Does the GRX name approve a complete replacement drivetrain?
No. Retain the individual model entries and obtain confirmation for the actual proposed assembly.
Does this describe every Scout sold later?
No. The evidence is the Australian 2021 catalogue, with its printed qualification that specifications can change.
