Ragley Blue Pig Drivetrain: Understand the Mixed 2021 Build
The Ragley Blue Pig drivetrain in the standard 2021 archive is a mixed Shimano 12-speed build. M7100 SLX shifting appears alongside an M6100 Deore chain and cassette. A seller describing the bicycle as SLX or Deore may therefore be referring to only part of the original equipment. Ask which component is meant, and compare actual model markings with the individual manufacturer rows.
Ragley Blue Pig drivetrain: Make a component-by-component record
The shifter is listed as Shimano M7100 SLX 12-speed, attached directly to the brake lever through iSpec EV. The rear derailleur is an M7100 SLX SGS with Shadow Plus. The chain is CN-M6100 and the cassette is M6100-12. Recording these separately gives a clearer account of the build than treating one name as a label for everything between the pedals and rear wheel.
The cassette sequence is 10, 12, 14, 16, 18, 21, 24, 28, 33, 39, 45 and 51 teeth. The Nukeproof Neutron wheelset is described as Micro Spline. These details identify the documented cassette and wheel pairing; they do not establish the freehub on a wheel that a later owner has substituted. Look at the actual hub and cassette identities before ordering a replacement.
Do not borrow missing information from the Race
The Race’s full specification instead names an XT M8100 shifter and rear derailleur, an M7100 SLX chain and an M7100 10–51 cassette. Its introductory full-SLX wording conflicts with those detailed rows. That discrepancy is worth preserving, but it should not change what the standard model’s own rows say. Use the exact version when recording an original build.
The standard page’s saved full-specification text does not supply a crank model or chainring tooth count. Do not fill those gaps with an assumed Deore crank, an image-based guess or a part seen on another year. A specific gearing calculation or crank replacement discussion needs the missing identity from the actual bicycle or a suitably confirmed model record.
Investigate modifications without treating them as faults
A different cassette, shifter mount or derailleur can reflect a later repair rather than an incorrect frame description. Request an explanation and supporting service information. Conversely, an original-looking component does not establish the condition of the chain, cassette or other fitted parts. An appropriate inspection should assess condition separately from a successful comparison with the historical list.
For context beyond the individual drivetrain, use the Ragley topic and the existing Ragley introduction. Keep a record of confirmed model numbers and unresolved items. This provides a useful starting point for workshop advice without presenting a historical component mix as universal compatibility approval or an assembly guide.
FAQ
Is the standard 2021 drivetrain entirely SLX?
No. The archive mixes M7100 SLX shifting with an M6100 Deore chain and cassette.
Does the original wheel specification say Micro Spline?
Yes, for the listed Nukeproof Neutron wheelset; inspect any later replacement wheel separately.
What crank model can be concluded from these rows?
The saved full specification does not name it, so do not infer a crank from the shifting group.
