Can anyone tell me, if theres any major difference between the 2011 and 2012 rpm? I can get a couple of 2011 rpms for a good price, but i dont want to buy them unless they flie like the 2012's... Ive tried the 2012 and loved them, but havent tried the 2011.. As far as i can see, there hasn't been any major changes between 2011, 12 and 13..

I would check to see if the 2011 has the "Splitstrut" construction. I can't remember exactly when they changed, but it was in the last year or so.

As far as I know, both the 2011 and 2012 had split strut.

One change was an increase in bar pressure for the 2012.

For what it's worth, I actually had a 2012 RPM and sold it b/c of the increase in bar pressure.

Thanks for the replys Both years have split strut construction. I think ill go for the 2011 and save me some dollars!
