Mondraker Foxy R Drivetrain Record: A Mixed Eagle Build
The Mondraker Foxy R drivetrain record is a mixed SRAM Eagle specification, rather than a build in which every component carries one group name. Mondraker’s United States 2024 archive lists an NX Eagle rear derailleur alongside an SX Eagle trigger shifter, chain and crankset. Read each field separately when comparing a used bicycle or preparing a parts enquiry.
Begin with the rear shifting components
The rear derailleur entry identifies NX Eagle, a Type 3 roller-bearing clutch, cage lock and a 1×12-speed description. The shifter is Trigger SX Eagle, 12-speed, while the chain is SX Eagle with Powerlock. This combination is what the archive prints. A listing that abbreviates the bicycle to “NX” or “SX” can therefore leave out useful information without necessarily identifying the wrong frame.
The cassette is PG-1230, 11–50T, 12-speed. The rear hub separately lists an HG freehub. Keep both descriptions together when asking about the original rear-wheel and cassette arrangement. Do not assume that every twelve-speed cassette has the same attachment simply because the number of sprockets matches, or treat a broadly similar Eagle name as approval for an unverified substitution.
Separate crank, ring and bottom bracket
The specified crankset is SX Eagle Boost with a DUB axle and direct-mount chainring. Its size line gives 170mm cranks for S and 175mm for M, L and XL, and prints CL55. The ring entry is 32T, CNC-machined alloy, X-SYNC 2. These fields describe different features; crank-arm length should not be confused with chainring tooth count or a chainline designation.
For the bottom bracket, the archive states SRAM DUB BSA, sealed bearings, 73mm. The frame description also gives a 73mm BSA bottom bracket and dedicated single-chainring design. This is useful identification information, but it is not a spacer diagram or an assembly procedure. A proposed crank or bottom-bracket change still requires a complete compatibility assessment and the appropriate installation instructions.
Describe the fitted system before ordering
Write down what the actual bicycle carries, especially if components have been replaced. A workshop can then distinguish a worn-part replacement from a change that affects several interfaces. Include clear cassette, derailleur, crank and chainring photographs where markings are legible. Preserve any unknown item as unknown rather than filling it from the archive when the bicycle visibly differs.
The Mondraker topic archive and Mondraker brand background explain the wider brand context. For a drivetrain purchase, a component-by-component list is more useful than that general story. Ask the supplier to confirm the whole intended arrangement; the archive alone does not establish chain length, present wear, adjustment quality or the condition of a used freehub.
Eagle component FAQ
Should every component say NX on this original build?
No. The archive explicitly combines an NX rear derailleur with several SX-labelled drivetrain components.
Does twelve-speed alone identify the cassette connection?
No. Keep the PG-1230 cassette and listed HG freehub information together when checking the actual arrangement.
Can the 73mm BSA entry supply installation spacer instructions?
No. It identifies part of the interface; the appropriate component instructions must establish the installation details.
Mondraker Foxy R drivetrain record: keep a useful record
The useful Mondraker Foxy R drivetrain record preserves each named part and its separate measurement. This supports a precise repair or replacement conversation without turning an abbreviated group name into a claim about the complete bicycle.
