Strengths:    None so far

Weaknesses:    Difficult to tune
No "happy all-around" set up
Noisy when suspension extend
Expensive


Bottom Line:   
I installed the shock on my Devinci Dixon 2012 and went for one of my regular ride of 22 miles ride / 3100 ft climbing and I could not get my bike's rear suspension to work normally despite all my attempts to set up the shock.

I am 200lbs and I tried all the possible set up to adjust the sag and rebound. By the way, this is not my first X-Fusion rear shock. A "hard stop" noise (metal to metal contact) can be heard when the suspension extends after compression if I set the initial sag at 20-25% (10-13mm / 50mm). It disappeared with a 30-35% set up but ended up being a way too soft and affecting the geometry.
On the trail, the rear shock is not predictable by tending to lock (or not) over the rocky section regardless of the damper adjustment position (I had a pump with me). I never had this problem with the Fox Float RP23 that the X-Fusion shock is supposed to replace. It is very difficult to keep control of your bike when the rear suspension decides to lock over baby head size rocks. On the other end, the rebound also seem to have a mind on his own by not being predictable feeling that the suspension is not controlled and kicking you when you go over 3-4 smooth bumps in a row.

I am not happy at all with my ride with X-Fusion as the trails that I nailed on a regular basis became a challenge using the same bike and setup minus the rear shock. It is just not fun. Now, let's see how X-Fusion handles my claim...

Strengths:    Smooth stroke, wide range of rebound adjustment, 3 levels of compression platform damping.

Weaknesses:    No full lockout; can't fine tune compression preset levels.

Bottom Line:   
I bought this shock as a replacement for the X-fusion O2 R shock that came stock on my Pitch. The Pitch bobs like mad when hammering out of the saddle, so I was looking for some compression damping. This RCX is a later model X-fusion shock than my O2 R. It has the same wide range of rebound adjustment, but doesn't seem to dive into the mid range as quickly, so I run slightly lower air pressure with the RCX. There are three preset levels of "platform" damping. At the firmest level, the bike still bobs a bit when out of the saddle, but the platform is very firm. You wouldn't want to use this setting on rocky trails.

Mostly, I wanted the platform for long road and firm dirt road stretches ridden to access trails. The firmest platform setting handles this well, but I sometimes wonder if I'd be better off with the RLX, which supposedly has full lockout and a single platform setting. Having three levels of platform from which to choose on the RCX, though, turns out to be a really nice feature I'm not sure I'd trade this feature for full lockout. I'd always assumed the Pitch pedals just fine when seated, but being able to add a little platform, or a little more noticeably enhances efficiency in some situations, like when climbing on rough terrain. I find that I do use the three levels of compression damping for different situations. Full open on descents is sensitive and smooth, and you can't beat the price. No complaints on this shock!

Fox RPL vs X-Fusion O2 RCX shock for Ibis Mojo SL Special Blend

My Ibis Mojo Special Blend came with a Fox RPL shock even though the specs say it comes with an X-Fusion O2 RCX. I don't know if this is an upgrade or a downgrade. I bought the bike from (which is the same as competitive cyclist). Should I call them and ask them if they can exchange it or am I bett ... Read More »

X-Fusion O2 RCX vs Fox RP23 (with adaptive logic)

Ok maybe a long shot here wondering if any one has actually used both these shocks? I am looking for another shock option for my Reign X. I am happy enough with the Fox RC2 but want something to throw on for more trail use.Read More »

X-fusion O2 RCX versus Fox Float RP23

I have a Nomad 2 (2010) which originally came with a Rockshox Monarch 3.3 shock. After a little more than 1 season, the shock started leaking (air and oil) even though it was serviced about 3 - 4 months earlier. The shock had to be sent back to Rockshox, but even they couldn't fix it, so they sent m ... Read More »
