The 525 is a range of cold drawn chrome-molybdenum tubes, all precision butted, using either seamless or welded raw material. The material is suitable for TIG welding and brazing, with lug or lugless construction. 525 will be found in frames with combinations of all 8 tubes, 3 main tubes down and seat tube and seat tube only. The decal will clarify the tubes used by each builder. We recommend 631 or 525 forks for use with 525 road and touring frames.

  Reynolds also use the 520 decal for Reynolds chrome-moly tubing made under license to our specification.
