About Reynolds Cycle Technology

Reynolds Technology Ltd. of Birmingham, England, holds the original 1898 patent for the butted (variable wall thickness) cycle tube and continues the innovation today with ultra high strength metals. The material selection for Reynolds cycle tubing is broad and includes among others: Reynolds 953, a stainless maraging steel with a maximum tensile strength of 2000 MPa (290,200 psi); Reynolds 921, the newest in the stainless line, is a cold worked high strength austenitic stainless steel with a tensile strength of over 1000 MPa (145,100 psi); Reynolds 853 is a seamless, air-hardening, cold drawn and heat treated steel with a maximum tensile strength of 1200 MPa (174,120 psi); Reynolds 631, with the same chemistry as 853, has a maximum tensile strength of between 800-900 MPa (116,080 - 130,590 psi). In the heat affected zone both 631 and 853 gain strength in excess of heat treated chrome molybdenum steel. Reynolds work with key partners around the world to develop metals with technical advantages, as each material may have different benefits to offer on strength, stiffness, fatigue life, vibration damping or damage tolerance. Regardless of the type of cycle tube material you choose to build with, rest assured that Reynolds quality procedures are accredited to ISO 9002 Standards. Please note the following regarding Reynolds cycle tube inventory held by Torch and File: - All tubing listed on the site is available for immediate shipping from the T&F warehouse in Portland, Oregon. - T&F supplies the full range of Reynolds tubing on special order. Contact T&F directly for special orders. - Items in the parts list not marked with an "X" are not stocked by Reynolds on a regular basis but may be available. Please inquire.

Bike Biz has an article out about one of Reynolds new projects:

Butted tubing technology is being used in a bid to create a lightweight car by Reynolds Technology, Caterham Cars and Simpact.

Reynolds Technology's Keith Noronha added: “Our butted tubes have contributed to weight reduction in diverse applications from bicycle frames to NASA spacecraft projects. This project aims to prove that car designers can re-think how to use steel - a sustainable and recycleable material – whilst meeting challenging targets on stiffness and driveability. The Caterham Seven should be the first car to incorporate these innovative aspects.”
