I have one very simular a DRC ===> 
        
http://www.cycletreads.co.nz/images/...300&height=350
         It won't quite fit under the seat or
        
 in the tail unit.. but I carry it in the
        
 tail bag with the rest of the tools , 
        
 tubes , patches etc..
        
 the DRC one comes in a bag with
        
 ties to strap it on..
