Shimano RXO for cross country racing?
Is this a heavy brake system? Power really strong with a 180mm rotor?
You mean RX100 for road bikes? Those were good brakes, very light and powerful however not suitable for mountain biking besides you can't mount them on rotors. I suggest go for Shimano SLX or XT disc brakes instead.

I think the 180/160 combo would be more than what is needed for XC racing (Formula has put the RO in the FR/DH category), but perfectly doable. I bought the RXO to try on my Nomad (but used my existing 203/180 rotors). I only have 1 or 2 rides so far, but they are strong with good modulation. As comparison, the old Megas that I took off may have better modulation, but may have less power. Very small differences though.
But I do not like the new Formula rotors. Seem difficult to set up right, and tend to be noisy when well used (my limited experience). I tried to use the 180 on the rear of the Nomad, but never could quiet it down while breaking it in (with many adjustments). I am using the 180/160 rotors that came with the RXO on my XC HT with the K24s. They seem OK, but I can "feel" that they are trying to sing. I never heat those up though. The new rotors are very light.
They had those for $99 each last week - one of their daily deals. Almost jumped on 'em just for the heck of it.
Those look like RO levers in that Jenson link, think Jensons description is wrong.
That must be the reach adjust add on. I love my rx brakes

I received them and they look nice. The rotors do seem flimsy. It goes look like they give much rotor clearance but my old Bianco Oro Puro's don't either. Hopefully they won't be so temperamental. I may sell them on Flea Bay....not sure yet.
