Ragley Blue Pig Brakes: Identify the Fitted 2021 Variant
Ragley Blue Pig brakes cannot be identified reliably from the standard 2021 model name alone. Its manufacturer specification lists a Shimano Deore M6100 lever with M6120 caliper and resin pads, or SRAM Level T hydraulic discs. Establish which system is actually fitted before asking about pads, servicing or replacement parts. The archived alternatives are not interchangeable service instructions.

Ragley Blue Pig brakes: Read the lever and caliper together
The Shimano entry names separate lever and caliper models. Preserve both in a parts request instead of describing the whole assembly only as Deore. If the actual bike has the SRAM option, do not carry the Shimano pad description across to it. A clear photograph of the installed caliper and its identification is more useful than an assumption based on the original paint colour.
The Race is another distinct record: its 2021 specification lists an M7100 lever, M7120 four-piston caliper and finned resin pads. Those names should not be transferred automatically to the standard model. A seller may have changed either assembly, so ask what work was done and which components remain from the published build. Component identity and present braking condition are separate questions.
Distinguish the mount from the rotor
The frame section lists a Post 160mm brake mount. The complete-bike rotor row gives 203mm/180mm, understood in the build’s front/rear sequence. A mount description is not the same as the installed disc diameter or a promise that no adapter is used. The saved table does not identify a complete adapter and fastener combination, so do not invent one from those two numbers.
Ragley’s contact FAQ gives a maximum recommended rear rotor size of 180mm. Preserve that rear-specific limit. It does not establish a universal front maximum, because the front brake also depends on the actual fork and brake equipment. The archived 203mm front entry records this build; it is not approval for every alternative rotor on every fork subsequently fitted.
Use the archive for identification, then assess the bicycle
For an enquiry, collect the frame year, actual fork, lever and caliper model, and the markings on each rotor. Make clear which end of the bicycle needs attention. If there is doubt about operation, damage or the suitability of an existing conversion, obtain a competent assessment before riding. This specification guide does not supply bleeding steps, pad compatibility charts or torque values.
The Ragley topic and Ragley introduction explain the wider range. For the particular bicycle, keep any confirmed replacement references and workshop findings with its records. The useful result is an accurately identified brake system and an assessed assembly, rather than a guessed “upgrade” based only on a larger disc or a familiar groupset name.
FAQ
Did all standard 2021 bikes use the same brake?
The archive lists the Deore M6100/M6120 combination or SRAM Level T, so inspect the actual bicycle.
What rear rotor maximum does Ragley’s FAQ recommend?
180mm; this is a rear-specific recommendation, not a universal front limit.
Does Post 160 mean the complete bike used a 160mm rear disc?
No. It is the frame mount entry; the complete-bike rotor row is separate.
