Seat post head assembly

A seat post head assembly comprising:

• a seat post, the seat post to couple with a seat tube of a vehicle;
• a housing coupled to the seat post, the housing comprising:
• a cylindrical bore therethrough;
• a first threaded chamber at a first location of the housing;
• and
• a second threaded chamber at a second location in the housing,
• the first threaded chamber and the second threaded chamber oriented to intersect the cylindrical bore;
• a rotatable core insertable into said cylindrical bore, the rotatable core comprising:
• a first inner seat rail clamp at a first end thereof;
• and
• a second inner seat rail clamp at a second end thereof,
• the second end opposite the first end;
• a first outer seat rail clamping member coupled to the first inner seat rail clamp to form a first seat rail clamp;
• a second outer seat rail clamping member coupled to the second inner seat rail clamp to form a second seat rail clamp;
• the first seat rail clamp and the second seat rail clamp to fixedly clamp a set of seat rails of a seat and provide independent adjustment of a fore-aft location of the seat without affecting a pitch of the seat;
• a first threaded member to thread into the first threaded chamber and contact a first portion of the rotatable core,
• the first threaded member to adjust the pitch of the seat without affecting the fore-aft location of the seat;
• and
• a second threaded member to thread into the second threaded chamber and contact a second portion of the rotatable core,
• the second threaded member to provide a physical hard stop to reduce pitch slip without affecting the pitch or the fore-aft location of the seat.

A seat post head assembly comprising:

• a seat post, the seat post to couple with a seat tube of a bicycle;
• a housing coupled to the seat post, the housing comprising:
• a cylindrical bore therethrough;
• a first threaded chamber formed through the housing at a first angle;
• and
• a second threaded chamber formed through the housing at a second angle different than the first angle,
• the first threaded chamber and the second threaded chamber oriented to intersect the cylindrical bore;
• a rotatable core having an elongated cylindrical shape, the rotatable core inserted into said cylindrical bore and rotatable within the cylindrical bore, the rotatable core comprising:
• a first inner seat rail clamp at a first end thereof;
• and
• a second inner seat rail clamp at a second end thereof,
• the second end opposite the first end;
• a first outer seat rail clamping member;
• a first clamping adjustment member to fixedly couple the first outer seat rail clamping member with the first inner seat rail clamp to form a first seat rail clamp;
• a second outer seat rail clamping member;
• a second clamping adjustment member to fixedly couple the second outer seat rail clamping member with the second inner seat rail clamp to form a second seat rail clamp,
• the first seat rail clamp and the second seat rail clamp to fixedly clamp a set of seat rails of a seat and provide independent adjustment of a fore-aft location of the seat without affecting a pitch of the seat;
• a first threaded member that threads into the first threaded chamber and contacts a first portion of the rotatable core,
• the first threaded member to adjust the pitch of the seat without affecting the fore-aft location of the seat;
• and
• a second threaded member that threads into the second threaded chamber and contacts a second portion of the rotatable core,
• the second threaded member to provide a physical hard stop against a change in the pitch of the seat as established by the first threaded member.
