    Abstract: PROBLEM TO BE SOLVED: To evaluate steerability such as "feelings of ride" or "steering stability" of a bicycle on the basis of objective indices.SOLUTION: According to a bicycle steerability evaluation method, steerability of a bicycle is evaluated using a signal that can be acquired from a rider when the bicycle travels on a road surface. The method includes a signal acquisition step S1 of acquiring an electric signal from an electrode disposed on the back of the head of the rider based on international laws 10-20, an analysis step S21 of executing signal analysis for extracting spectra of frequency components corresponding to Midα, Fastα and β waves from the acquired electric signal, and a classification step S23 of classifying the extracted spectra to any one of a plurality of categories for evaluating steerability of the bicycle on the basis of a criterion associated with the electric signal acquired from the electrode disposed on the back of the head of an examinee steering a reference bicycle traveling on the road surface on the basis of the international laws 10-20 and an evaluation value evaluating steerability of the reference bicycle inputted by the examinee.

    Abstract: PROBLEM TO BE SOLVED: To obtain a rubber composition which gives high hysteresis loss, fracture properties and processability as well. SOLUTION: A rubber composition comprises 100 pts.wt. of at least one rubber component selected from a natural rubber and synthetic rubbers and 1-120 pts.wt. of a softener containing 0.1-4 wt.% of an asphaltene component wherein a content of aromatic carbon (%CA) of the softener measured according to ASTM D2140 (conventionally referred to as a ring analysis) is preferably not less than 18. The softener is preferably prepared by mixing an asphalt with a processing oil and the asphalt is preferably a straight asphalt, considering easiness of purification of the softener.

    Abstract: PURPOSE: To reduce taking-out of mud to the possible minimum level when a traveling body escapes from a wet field or the like by completely covering a surface of a tread containing at least side surfaces of plural lugs arranged at intervals in the circumferential direction on the tread with a mud sticking preventive layer composed of an elastic body layer having low hardness. CONSTITUTION: A tire 1 is provided with plural lugs 3 arranged at intervals in the circumferential direction on a tread 2. A surface of the tread 2 containing a back face and a side surface of these lugs 3, a sidewall part and a shoulder area is completely covered with a mud sticking preventive layer on which a thickness is 5 mm and an average foaming diameter is 100μm and ASKAR-C hardness is 30 and specific gravity is 0.5 and which is composed of a foaming rubber layer of mixed type independent foam of natural rubber and polybutadiene rubber. Since mud hardly sticks at work time in a wet field, a weak place, a muddy place or the like, taking-out of mud when a traveling body escapes from a wet field or the like can be reduced to the possible minimum level.
