Boy, this is going to be a tough one.
The match up:
Rock Shox
Reba Race 100mm vs
White Brothers Magic 100mm
The subject vehicle will be the One 9 (aka
Red 5). Having logged several hours with the Reba on some of the best riding this region has to offer, I am going to put the Magic to the test on some of the same trails over the next week or so.

One of my favorite features on the Reba, is the handlebar mounted lockout. It works when you need it, and I have only ever forgotten that it was locked out once. The Dual Air chambers on the Reba are also some of the most versatile on the market.

You can control how plush the fork feels by changing the air pressure in the negative chamber relative the positive one. I have mine set at 95+/95- with the rebound setting 2 full turns back from the slowest position.
It is a very plush fork, with an even feel throughout the travel. I have measured a full 98mm of travel on this fork. Not too bad.
The Reba also features huge 32mm stanchions which provide outstanding torsional stiffness, with superior tracking through rough singletrack.
The axle to crown is 495mm (eyeballed)
Both forks in this test weigh exactly the same, so this is going to be a performance test. That's all we really care about anyway right?
The Magic has a single air chamber, with this fancy Inertia Magnetic Valve. What is it? In a nutshell, it is a smart valve that can tell the difference between forces coming from above, and forces coming from below. Once it figures it out, it can then react accordingly. In a sense, the fork is supposed to be able to tell if you are huffing and puffing up and out of the saddle, at which point is restricts the amount of oil that can travel through the damper assembly, thus firming up. Once you hit a rock or a hole though, it opens right up, allowing the fork to absorb the bump force.
Sounds cool doesn't it?

Well, one of the things that will affect the test, is the Magic's lower axle to crown height, a measured 490mm (or there abouts...). This will effectively steepen the HT a small amount, which isn't necessarily a bad thing, but it will drop the bars by roughly 5mm, which will in turn change the steering.
That is bad, as I love the way this bike handles.
There was enough room on the steerer tube for one 5mm spacer, which put the bars right back where I had them relative to the ground, which should help the bike maintain it's feel. I measured all of these things in my own half-assed way, just to keep everything consistent.
Some folks might take a more "scientific" approach to it, but frankly, all I care about is the ride.
I set the single air chamber up with the factory recommended 80psi, and the IMV at 16 clicks in (I counted 33 possible). I will be fiddling with it tomorrow at the
Millstone Trails in Barre.
It will be nice to see what kind of travel it actually gets. I'm still disappointed with the BW 0.8, but this is a whole new fork.
On a side note, I have also switched my trusty WTB Exiwolf 2.3s for some Maxxis Ignitor 2.1s.
They are practically the same size, with the main differences being tread style and weight. Look for that review in a few days, after I have had some time on them. As I currently have only 1 ride on the Ignitors, I am not really prepared to say anything more than, so far, I like them.
Like my Reba, I also really like my Exi's.
But that, is another show...
I'll be back tomorrow with my initial thoughts on the IMV, and some pictures.
