Last year we saw hlins debut all-new XC suspension at the races, and this year they are back with new electronically-controlled prototypes. The basis appears to be the same carbon-crown RXC34 fork and TXC2 Air shock, but now mechanical lockouts are replaced with electronic controls. In the pits, Titouan Carods BMC mechanics mostly kept everything neatly wrapped up. But out on the track we got a closer look at what looks like the smart controller added onto the rear shockhlins prototype electronic XC MTB suspension (All photos/Cory Benson) Spotting Carod warming up for the Nov Msto na Morav short track over the weekend, we noticed and extra box sticking out of the front of his hlins TXC Air rear shock, tucked in between the front shock mount on his BMC Fourstroke XC race bike. It turns out that what we spotted seems to be a prototype electronically-controlled cross-country air shock and fork from the Swedish suspension specialists.Its not quite the first time weve seen prototype electronic suspension from hlins. Weve seen a few variants of Loic Bruni racing electronic hlins DH prototypes, both on a reconfigured Specialized Demo and an all-new prototype bike thats still in development.But while all that prototype DH tech was well-covered under big cowls, this BMC is fitted with much smaller tech that more easily tucked into the otherwise stock frame. Plus, its being left uncovered, at least for racingPrototype electronic TXC Air shock wrapped up tight in the pits, mostlyFor the most part, the Team BMC Racing mechanics tried to keep the new hlins electronic prototypes on Carods bike wrapped up inside a velcro-on neoprene sleeve. At least when they werent working on the bike. But the weekends cross-country racing started off quite wet & muddy, so there were plenty of times when they pulled back the covers to service the bike.So, why might they keep the prototypes uncovered out on the track and for racing, yet wrap it up in the pits?My guesses would be 1 or 3 possibilities. Either the electronics need airflow to get the best function, or the cover might simply impede some movement? The rider or mechanics may need easy access on the track to make adjustments, otherwise inaccessible under the neoprene cover? Or perhaps, they just need to see how it stands up to the elements in a real-world racing scenario.In any case, the result is that we got a pretty good sneak peek by keeping our eyes open.Electronic prototype hlins RXC34 Carbon Air forkOK, so we know theres some electronic control. But what suspension are we working with?It appears that only Titouan Carod is racing on the prototype electronic suspension. The rest of the BMC team gets mechanical remotes. And it looks like hes working with the hlins RXC34 fork that we detailed last summer, based on these lowers. Of course, we probably wouldnt call it an m.1 fork anymore, as clearly hes got some custom next-gen tech inside. And his name on the fork legs.What electronic controls that exist are entirely in the left leg. Thats where the 3-position (Open, Pedal, Lock) OTX14 compression damper cartridge is on the standard hlins RXC34 fork. (The volume-adjustable air spring is in the right leg.) We dont see an obvious external adjustment here. But that small gold screw is the same as found on the front of the shock control/battery box. So it might offer some adjustability more than just holding the cap on.A single wire (& inline connector) exits, and heads into the frame next to the mechanical dropper remote cable. Presumably, the fork then connects with the system brain, at the rear shock.Tidy Electronic Remote ControlFor rider mode control of the prototype electronic suspension, hlins gives Carod a tidy little thumb-actuated twist shifter/switch. Wired into the system through the Fourstrokes internal frame routing, the controller doesnt take up much space in between the brake lever and grip. (Its wire enters the opposite of the headtube together with the rear brake.)That mode shifter looks a lot like a Zirbel Ring Switch with their WE03 Ring for the thumb button. Im not really sure, since Zirbels standard Ring Switch typically has 2 wires coming out of it. But perhaps hlins just worked together with Zirbel to create the remote they needed for their prototype suspension controls.Uncovered and Up Close!Now for the proper spy shots!Team BMC mechanics were as careful as they could be to keep their hlins prototype electronic XC suspension out of direct sight in the pits. But once racing was underway, the mechanics unwrapped the shock.Yet, what they kept covered doesnt really reveal too much after all.All we can really see is a narrow box extending forward from the damping controls of the TXC Air shock. In fact, a closer look at the photo we snuck from the workstand (above) suggests the shock itself is wholly unchanged. Theres just a small electronic actuator bolted on top, instead of the mechanical remote actuator, which of course makes sense for simplicitys sake.Then what you get is that this box is just the battery and brain of the system. We see the two wires coming in from the fork & remote switch to connect to the box just in front of the upper shock eyelet. And the wire for the rear shock power & control exits out of the middle of the box on the left/non-driveside.

And its only being race-tested on one riders bike. So dont expect it too soon. With that said though, it was less than half a year between when we first saw hlins XC suspension prototypes until the time you could actually buy them. So maybe we wont have so long to wait!Ohlins.com/MountainBikeThe post hlins Prototype Electronic XC Suspension Raced on the MTB World Cup: Uncovered! appeared first on Bikerumor.
