dhcpcd deleting gateway

                          I'm trying to switch from DHCP to static IP by using dhcpcd.
When I switch from static to DHCP I'm configuring that eth0 (which used to have the static address) will also be the one with the DHCP address. But somehow dhcpcd seems to remove the gateway as well when it starts.

So if I originally have   

    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    0.0.0.0         192.168.50.1    0.0.0.0         UG    0      0        0 eth0
    192.168.50.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0

It will become 

    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    192.168.50.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0

This is my dhcpcd.conf file

    # A sample configuration for dhcpcd.
    # See dhcpcd.conf(5) for details.
    
    # Allow users of this group to interact with dhcpcd via the control socket.
    #controlgroup wheel
    
    # Inform the DHCP server of our hostname for DDNS.
    hostname
    
    # Use the hardware address of the interface for the Client ID.
    #clientid
    # or
    # Use the same DUID + IAID as set in DHCPv6 for DHCPv4 ClientID as per RFC4361.
    # Some non-RFC compliant DHCP servers do not reply with this set.
    # In this case, comment out duid and enable clientid above.
    duid
    
    # Persist interface configuration when dhcpcd exits.
    persistent
    
    # Rapid commit support.
    # Safe to enable by default because it requires the equivalent option set
    # on the server to actually work.
    option rapid_commit
    
    # A list of options to request from the DHCP server.
    option domain_name_servers, domain_name, domain_search, host_name
    option classless_static_routes
    # Respect the network MTU. This is applied to DHCP routes.
    option interface_mtu
    
    # Most distributions have NTP support.
    #option ntp_servers
    
    # A ServerID is required by RFC2131.
    require dhcp_server_identifier
    
    # Generate SLAAC address using the Hardware Address of the interface
    #slaac hwaddr
    # OR generate Stable Private IPv6 Addresses based from the DUID
    #slaac private
    
    # Configure IPv4 only
    ipv4only
    
    # Don't set any default routes
    nogateway
    # Allow the following interfaces
    allowinterfaces eth0


I use dhcpcd eth0 to request an IP

What am I doing wrong?
