Abstract

A bicycle brake arm includes a sleeve, a brake arm body, first and second abutments and a first bearing member. The brake arm body has a mounting portion. The brake arm body is rotatably arranged with respect to the sleeve. The first and second abutments are axially arranged with respect to each other on the sleeve. At least a part of the brake arm body is disposed between the first and second abutments. The first bearing member is disposed axially on a first outside of the mounting portion of the brake arm body about the sleeve. The first bearing member is axially disposed between the first and second abutments.

         2 . The bicycle brake arm according to  claim 1 , wherein
 at least one of the first and second abutments is axially adjustable with respect to the sleeve.   
     
     
         3 . The bicycle brake arm according to  claim 2 , wherein
 the at least one of the first and second abutments further includes first and second locking members that are axially adjustably coupled to the sleeve.   
     
     
         4 . The bicycle brake arm according to  claim 1 , wherein
 one of the first and second abutments is fixedly coupled to the sleeve.   
     
     
         5 . The bicycle brake arm according to  claim 4 , wherein
 the one of the first and second abutments radially extends from the sleeve.   
     
     
         6 . The bicycle brake arm according to  claim 4 , wherein
 the one of the first and second abutments is integrated with the sleeve.   
     
     
         7 . The bicycle brake arm according to  claim 1 , wherein
 the first bearing member includes a thrust bearing.   
     
     
         8 . The bicycle brake arm according to  claim 1 , wherein
 the first bearing member includes a bush as a dry bearing.   
     
     
         9 . The bicycle brake arm according to  claim 1 , wherein
 one of the first and second abutments further includes an engagement portion that is configured to be non-rotatably engaged with a brake attachment section of a bicycle frame while the bicycle brake arm is attached to the bicycle frame.   
     
     
         10 . The bicycle brake arm according to  claim 9 , wherein
 the engagement portion further includes an axial protrusion that axially protrudes with respect to the brake attachment section of the bicycle frame.   
     
     
         11 . The bicycle brake arm according to  claim 1 , further comprising
 a fixing member extending through the sleeve.   
     
     
         12 . The bicycle brake arm according to  claim 11 , wherein
 the fixing member includes a threaded section that is screwed to a threaded portion of the sleeve.   
     
     
         13 . The bicycle brake arm according to  claim 11 , wherein
 the fixing member includes a threaded section that is configured to be screwed to a brake attachment section of a bicycle frame while the bicycle brake arm is attached to the bicycle frame.   
     
     
         14 . The bicycle brake arm according to  claim 11 , wherein
 the fixing member extends beyond an axial end face of one of the first and second abutments.   
     
     
         15 . The bicycle brake arm according to  claim 1 , further comprising
 a second bearing member disposed axially on a second outside of the mounting portion of the brake arm body about the sleeve, the second bearing member being axially disposed between the first and second abutments.   
     
     
         16 . The bicycle brake arm according to  claim 15 , wherein
 the first bearing member is axially disposed between the first abutment and the mounting portion of the brake arm body, and   the second bearing member is axially disposed between the mounting portion of the brake arm body and the second abutment.   
     
     
         17 . The bicycle brake arm according to  claim 15 , wherein
 at least one of the first and second bearing members includes a thrust bearing.   
     
     
         18 . The bicycle brake arm according to  claim 15 , wherein
 at least one of the first and second bearing members includes a bush as a dry bearing.   
     
     
         19 . The bicycle brake arm according to  claim 15 , wherein
 one of the first and second abutments is axially adjustable with respect to the sleeve, and   the other of the first and second abutments is fixedly coupled to the sleeve.   
     
     
         20 . The bicycle brake arm according to  claim 19 , wherein
 the other of the first and second abutments radially extends from the sleeve.   
     
     
         21 . The bicycle brake arm according to  claim 19 , wherein
 the other of the first and second abutments is integrated with the sleeve.   
     
     
         22 . The bicycle brake arm according to  claim 19 , wherein
 one of the first and second abutments further includes an engagement portion that is configured to be non-rotatably engaged with a brake attachment section of a bicycle frame while the bicycle brake arm is attached to the bicycle frame.   
     
     
         23 . The bicycle brake arm according to  claim 22 , wherein
 the engagement portion further includes an axial protrusion that axially protrudes with respect to an attachment face of a brake attachment section of a bicycle frame.
