Product Description

RockShox had initially set the bar for 29er forks when they first released the Reba 29. They've stepped up to the plate with a tweaked and dialed version of the Reba 29 to set them ahead of the pack once again. The RockShox XX Reba 29 Dual Air 100 Fork gets their XX Motion Control damper assembly, which allows the use of hydraulics instead of cables to actuate the remote lockout. That's the single biggest difference between XX forks and their non-XX brothers -- the XLoc. It's a hydraulic remote that is actuated with a light click at the handlebars. Press to open. Press again to lock. The button mechanism is made from 6061-T6 aluminum and is at the end of a flexible hose that's filled with 5W suspension fluid. The hydraulics integrate with the XX Motion Control damper to turn the lockout on and off. It comes pre-bled and ready to operate, so all you'll have to do is ...the XLoc helps make this the ultimate 29er cross-country suspension fork... cinch the aluminum housing onto your handlebar with the included Ti hardware. The entire hydraulic system is 60g lighter than the cabled PushLoc system. You can install the XLoc onto its own clamp, or it can become the top portion of your MatchMaker XX clamp system so you can mate the lockout, shifter, and brake lever all into one unit.The Reba is air sprung. In fact, this XX version uses their Dual Air system. The fork has air valves on the top and the bottom of the left leg, one for your positive air spring and one for the negative air chamber, respectively. The great thing about Dual Air is that you can adjust the shape of the air spring -- meaning you can make the fork more or less responsive over small bumps or better able to absorb big hits with your included shock pump and a few minutes of tuning time.This RockShox Reba XX 29 Dual Air 100 Fork has 100mm of travel and is designed for 29" wheels. It comes with spacers that you can add or remove internally to adjust the travel down to 80mm or up to 120mm if you prefer.

Strengths:    ~Dual Air means very plush fork
~Tapered steer tube
~Hydraulic XLoc, w/ Floodgate, for varying degrees of lockout
~32mm stanchions, for stiction-free turning
~51mm offset, for reduced trail, with quicker turning
~Adjustable, internal shim stacks, for ride height settings(80mm-120mm)
~Longer service intervals
~Rock Shox makes replacement fork decals, when trashed by trails

Weaknesses:    ~1809g(3.99 pounds) w/ 7.5" steer tube
~Only comes in 9mm QR dropout
~No longer in production. SRAM tech documents nearly impossible to find online

Bottom Line:   
Introduced in the Fall of 2010 - This fork gave Fox a good run for their money. My fork is the Trek G2-specific, 51mm offset model. Increasing the dropouts to 51mm from the center of the steering axis allows a frame with a slacker head tube steer much quicker, by reducing the trail figure. Another added benefit is no more wheel/toe overlap too.

On the trail - this fork feels lively, due to the dual air chambers, for positive and negative spring rate. Initially, it is a bit tricky to set up correctly - but once dialed-in, it becomes endlessly plush for a 100mm fork. Best to set negative air 10psi less than positive for the ideal balance. The dampener dial is 10 turns - so I set mine towards the Rabbit(fast rebound), with six turns away from slow rebound(Turtle), for XC/Trail riding. good thing about the XLoc remote is the Floodgate has a dial so you can determine how hard you want full lockout to be. At max gate - the fork is quite stiff, maybe moving 8mm before it stops travel. A large bump will blow off pressure and absorb the hit - so there is some "intelligence" built into this fork.

This fork is significantly heavier than it's Solo Air, SID younger brother, which is about 3.2 pounds. My front wheel hub is a 15mm thru-axle, yet I was able to use it with this 9mm QR dropout fork, via a lightweight DT Swiss 9mm thru-bolt RWS axle and 9mm-to-15 TA adapter, with zero performance degradation whatsoever.

All in all - it's a great fork, given you can still find one. RS should have never done away with dual air chambers - but I can understand why they did.....lighter weight overall. Set this fork up right, and you'll never blow through all it's travel. Service it using larger-than-OEM o-rings and seals and the fork should last you many, many seasons.

Strengths:    Plush, reliable, pushloc works well on the fly

Weaknesses:    Unacceptable flex and twist under heavy loading as in downhill braking- serious amount.

Bottom Line:   
Stay away from the 9mm QR version (unless you want to buy mine!). Under heavy loading technical terrain, front end feels very unstable. Most of time, I am forced to lock the fork to decrease flex and twist and bring confidence back to the front end. Should have asked around first about QR 29er forks. At least with the Reba, they suck. With the 15mm through axle version, I speculate that the above weakness would go away. If so, I would 4-5 chili it. I am coming from a raked rigid steel fork so my demand for stiffness may higher than average.
