You ARE missing the important fact that they look gash though, this is why I won't use them.

The way I see it, first you need to figure out the tensile of the Al alloy used and the the weight of the small tube sticking out.
Then with that info you could figure out how fast the wheel would have to spin in order to cause deflection of the tube.
I would guess the RPM needed to cause the tube to bend would be higher than this bike is capable of producing.
I also find it a bit odd that the aftermarket wheel manufactures don't know about the dangers of 90* stems..... I mean why would Marchesini put 90* stems in their ad photos?

They also sell them directly:

BST, the same thing....90* stems
I could go on but I just leave it at that, Until I actually see a 90* valve that has failed due to it flexing itself apart, I just can't believe it.
Plus the fact I have run them for years on my bike ( and yes it has reached its terminal velocity or around 160MPH during that time) with no issues what so ever.
Then I would say around 80% or more of the club racers in the Bay Area also run them and I have never seen one fail.

any ideas what i can use for the WP one ( please don't say cable ties or Jubilee clips)cybercarl wrote:Got ya

The only thing wrong with cable ties is I don't trust half of you wombles not to cut them and nick my sh1tbigtwinthing wrote: any ideas what i can use for the WP one ( please don't say cable ties or Jubilee clips)
Other than that they're fine 
So these will work with an ohlins reservoir.....?Jamoi wrote:These SPA design ones are universal dude, so you'll be fine with them.

Choose from a cnc clamp:
Or as I did, x2 straps (essentially big jubilee's) with rubber blocks: £7
Pic please when fitted as I'll need some too.Jamoi wrote:Kev recommended SPA design for the straps and rubbers for the Penske shock resevoircybercarl wrote:Just taken delivery of my Spa reservoir strap
