This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2868 − 10 F2868 − 10 (Reapproved 2015) An American National Standard
Standard Specification for
Condition 2 Bicycle Frames
This standard is issued under the fixed designation F2868; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This specification standard defines a set of requirements for Condition 2 bicycle frames. Condition
2 is a vehicle usage classification defined in Classification F2043 indicating the type of riding and
surface condition intended by design. Included are specifications for establishing loads and other
criteria to be used with the matching test method.
1. Scope
1.1 This standard establishes testing requirements for the structural performance properties of Condition 2 bicycle frames.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard is applicable to adult size suspension and non-suspension bicycle frames.

3.1 Definitions:
3.1.1 bicycle frame, n—the structural member that supports the seat with rear connection for the rear wheel, front connection
via the head tube for the fork and lower connection for the crank/pedal assembly.
4. Classification
4.1 Condition 2 bicycle frame.
5. Performance Requirements
5.1 The bicycle frame shall be tested in accordance with the methods of Test Methods F2711, the Horizontal Loading Fatigue
test, Vertical Loading Fatigue test, and the Impact Strength test.
5.1.1 Horizontal Loading Fatigue Test—The frame shall be tested and must complete a minimum 50 000 cycles with a cyclic
load of 800 N tensile and 600 N compressive.
5.1.2 Vertical Loading Fatigue Test—The frame shall be tested and must complete a minimum 50 000 cycles with a cyclic load
of 1200 N to 120 N load in the compressive direction.
5.1.3 Impact Strength Test—The frame shall be tested with a drop height of 180 mm, and the permanent set of the frame and
fork shall be less than 40 mm.
