Ragley Blue Pig Steel Frame: What Changed for 2023?

2026-10-28

The Ragley Blue Pig steel frame name covers more than one geometry generation. The manufacturer’s 2023 frame entry describes a revised 4130 chromoly 27.5-inch model with longer reach, shorter seat tubes and a different fork-offset reference from the 2021 entry. Recognising that change helps when comparing a used complete bike with a separately advertised frame, even when both simply say Blue Pig.

Ragley Blue Pig steel frame: Read the changed geometry rather than just the material

The 2023 chart lists reach of 430, 455, 480 and 505mm from Small to Extra-Large, compared with 420, 440, 460 and 480mm in the 2021 chart. Its actual seat-tube angle is 75 degrees and head angle 63 degrees; the older table lists 74 and 63.75 degrees. These are named-generation references, not proof that one size letter supplies the same position in both frames.

Seat-tube lengths also differ: the 2023 figures are 380, 410, 440 and 470mm, against 380, 420, 460 and 500mm in 2021. The new chart lists a −50mm bottom-bracket drop rather than −45mm. These entries support a comparison of the published designs, but do not establish maximum dropper insertion or justify converting a previous frame to reproduce the newer geometry.

Keep the fork reference attached to the generation

Both frame sections recommend 150–160mm fork travel and tie 542mm axle to crown to a 150mm fork. Their offset entries differ: 46mm for 2021 and 37mm for 2023. Avoid mixing the later offset with the earlier geometry table to create a specification Ragley has not published. A proposed fork still needs confirmation for the actual frame and complete assembly.

Other interface names remain familiar: the 2023 frame lists a 73mm BSA bottom bracket, 31.6mm seatpost, 34.9mm clamp, 12×148mm Boost rear hub and ISCG 05 tabs. Shared labels help an enquiry, but are not blanket permission to transfer every part from an older build. Identify each component and any unresolved dimensions before treating a frame swap as straightforward.

Understand the coating statement within its limits

The 2023 page says Ragley’s steel frames are now ED coated and describes an electrically charged paint-bath process covering the inside and outside. That supports a statement about the coating described for this frame generation. It does not prove the treatment on an individual older frame, guarantee freedom from corrosion or replace an assessment of existing damage and condition.

For the wider range, use the Ragley topic and Ragley introduction. When inspecting an actual frame, establish its identity and service history rather than dating it from a colour or assuming a coating makes inspection unnecessary. Keep the documented generation, actual condition and proposed build plan together before deciding which frame is suitable.

FAQ

Is the 2023 Medium reach the same as 2021?

No. The published figures are 455mm for 2023 and 440mm for 2021.

Does the newer chart keep the same fork offset?

No. The frame entries list 37mm for 2023 and 46mm for 2021.

Does ED coating make a used frame corrosion-proof?

The page describes a protective process; it does not guarantee the condition of an individual frame.
