    need suggestions on what to buy (and maybe even some advise on installation process) for switching standard valve stems to 90 degree. Tire pressure settings, being as important as they are, make me want to switch to 90s on the front for easier access. Any help is appreciated

    I have the Bridgeport ones but don't remember where I got them. It's a great little mod though.

    I don't use them.... Changing enough tires they are a PITA to get the bead to set like a normal Straight stem.... Stock ones for me...

    I'm confused - how does the valve stem come into play when seating the bead? I am not an expert here on tire changing but I have changed the tires on my bike multiple times using the no-marr system. How has a 90-degree valve stem impacted your tire changes?

    Some don't have as much flow rate as OEM style so you don't get the quick rush of inbound air and getting the initial seal can be more difficult

    What Dave said... It cuts the air flow almost in half.. Your always removing the cores in the stems on every tire change which is a PITA after awhile.. Especially when the lube dries ect after failed attempts... I have a Pneumatic machine but why deal with the hassle of changing the same tire twice ect... Nothing wrong with stock stems as long as they are not old... I do have straight metal ones too...

    In the interest of full disclosure I do use the 90 degree stems, the occasional hassle with bead seating is worth it to me for the convenience of checking the front tire pressure without rotor burns!

    Moto-D is what I use on my SV. Reminds me to pick up another set for another extra set of rims I got coming.

    I use the 90* stems on the front wheels but, prefer the standard upright valve stem for the rear wheels. easier to take pressure readings. Ski
