Actualy I do have Lezyne road drive wich can be easily set with a spring. I saw the gauge drive also. Maybe someone know if it has a spring ?
I was wrong with bosses, my English isn't perfect. I actually mean pump peg. I just dont know wich form I should give to those pump pegs.
I saw that some people have lezyne pumps mounted on seat stays so I was wondering to see how that's done.
Sorry for my English.
