Zeb? Yes, that is correct, RockShox’s brand new, extra-beefy single crown fork is known as the Zeb. That name stems from Zebulon Pike, the explorer that had been traipsing around at the hills near RockShox’s Colorado Spring, Colorado, headquarters at the ancient 1800s.
Unique name apart, the Zeb is placed between the Lyrik along with also the dual-crown Boxxer, and it is made for use on enduro and e-bikes. Available travel figures vary from 160mm all the way around 190mm, in 10mm increments( for 27.5″ or 29″ wheels.

There really are a total of five unique versions, with the very best place occupied by the Zeb Ultimate that is pictured here. That fork has each the sausage and whistles, such as a Charger 2.1 damper with adjustable rebound and large – and – low-speed compression. ) Next includes the Zeb Select+, a choice that will only be accessible on total cycles. It too utilizes the Charger 2.1 damper, but loses the high-speed compression alteration.
The Zeb Select is another option later on, which, such as the Select+ includes adjustable low-speed compression and rebound( but through a Charger RC damper.
The two cheapest (and least flexible ) choices are geared more in the e-bike audience. The only changes on the Zeb R are atmosphere rebound and pressure — it will not get much easier than that. There’s additionally a dual position edition of fork which may be changed from 180mm of traveling to 150mm together with the twist of a dial.
Increased stiffness has been the driving factor behind Zeb’s bigger stanchions and fresh arch layout, but in reason — a fork that is too rigid can feel unpleasant and hard to manage on long, demanding paths, however great the internals are.
So how much looser is your Zeb compared to the usual Lyrik? ) According into RockShox, it is 21.5% stiffer torsionally, 7 percent stiffer in regards to unwanted bending, and 2 percent stiffer fore / aft. Those amounts are comparing a 180mm Lyrik into some 180mm Zeb.
Extra stiffness generally will come with a bit more weight, and also my 29” 170mm Zeb Ultimate evaluation fork weighed in at 2250 g ) For mention, that is 250 g more than the usual Lyik, and 180 g less than the newly published Fox 38.
The Zeb’s arch is tilted slightly forward so as to present a bit more head tube clearance. Extra-girthy head tubes are seemingly becoming more common, though it’s occurring more in the eMTB arena. Speaking of all e-bikes, there is a 1.8” tapered steerer alternative. 1.8” steerers first popped up in Eurobike last year, also in the present time, it seems like the 1.8” steerer will stay in the aerodynamic kingdom. Of class, as soon as a business as large as RockShox gets behind something it is likely only going to be prevalent in the next few years.
Other external elements have the capacity to conduct a bolt-on fender (eventually ) with the 3 holes on the rear of the arch, and also to operate a 200mm rotor without having any adaptors. No miniature rotors allowed here 200mm would be the smallest you will have the ability to go. The Zeb utilizes a 15mm thru-axle, therefore 20mm thru-axle buffs need to continue waiting for this standard to produce a comeback from one crown world.
Side notice: I actually wish brake manufacturers can settle on 200 or 203mm rotors. Pick the other, please; there is no need for the two to exist. It’s good a Code caliper can bolt directly onto the Zeb without having to dig an adaptor, however passengers at the Shimano Circle will still must run two 1.5millimeter washers to receive their own brake caliper to align correctly.
What’s Inside? )
Inside of this Zeb Ultimate you’ll discover that a Charger 2.1 damper, which employs the exact same expanding bladder design that is used at a Lyrik or Pike. They’re not cross-compatible, however, since the Zeb’s damper was made to match individuals 38mm stanchions.
The goes to your DebonAir air spring. It’s similar, but not equal to this recently upgraded spring located at the Lyrik and Pike, that places the spring on the stanchion dimple which allows air to pass from the negative into the positive room, letting the fork to ride greater in its traveling. The Zeb’s adverse air volume is bigger in order to provide the fork a much more supple first part of its journey.
Thanks into the greater air quantity in the Zeb, the recommended air pressures are relatively low. Those lower pressures imply that altering adding or subtracting a pound or two of stress creates a more noticeable gap than it might on a fork which needs greater strain.
I have about a dozen rides around the Zeb thus much, lots of time to experiment and find the settings that work best for me personally. At 160 lbs I’m currently conducting 55 psi without a quantity spacers, while at a Lyrik, I’ll normally run 1-2 spacers and 80 psi. Even with no volume spacers there is a wonderful smooth ramp up in the end of the stroke, despite my best (or worst) efforts I have not had some horrible workouts.
The Zeb’s damper and air spring are extremely much like this Lyrik, however the 2 forks do feel different on the road. The Zeb includes a more muted texture compared to Lyrik when confronted with recurrent impacts, like a thin layer of memory foam has been laid over the floor. It’s like the difference in texture between conducting a DH casing versus a single-ply, trail casing scooter. The Zeb appears to filter out the tiny vibrations differently compared to the Lyrik, transmitting a bit less road responses to the handlebar. There’s nevertheless a very usable assortment of high- and – low-speed damping, it merely that all of the way open the Zeb seems like it takes the advantage of sharp strikes somewhat differently than the usual Lyrik.
I’ve taken the Zeb on multiple 3,000 feet descents and have not had any problems with it being overly rigid. The additional stiffness is evident, even though it’s worth mentioning that I really don’t have any complaints regarding the stiffness or damping operation of a Lyrik. With that the Zeb, that additional stoutness could be sensed steep, sharp turns, the kind where the majority of your weight is straight onto the fork, and on tough straightaways, when letting off the wheels and blowing is the smartest choice, or the most fun.
How does it compare to the Fox 38? ) Well, that the Zeb is significantly less costly by $200, and it wins at the fat game, leading to at 2250 g in comparison with this Fox in 2430 g ) The 38 does have independently adjustable high-speed rebound damping, also it has those nifty air bleed vents on the rear of the thighs, along with a pinch bolt axle system.
I’ve been happy with the operation of the two forks up to now, but because both are new choices this year it is well worth carrying a much deeper dip in their managing to see if there are some regions where you really stands above another. Pinkbike’s Dan Roberts was placing both forks into the evaluation on the steeps of Champéry — try to find a comprehensive head-to-head contrast after this summer.
