you can get a saracn mech from several places 1 your local bike shop should be able to order one for you 2 try tarty bikes theyve got everything 3 go direct to saracen and order one from them echo pure frame seem to match any colour but keep it simple they look poo if there over built finally about gears no everyone runs them but no everyone is the same, its all personal choice, its a good idea if you ride a distance between spots , but then again its just something else to go wrong hope i have helped
