Trickstuff's Updated Trixer Hydraulic Gyro - Crankworx Innsbruck 2019

Jun 13, 2019
by James Smurthwaite  

Trickstuff unveiled a production ready version of their hydraulic gyro at Crankworx Innsbruck. A gyro disconnects the brake hose under the stem so that trick ferrets doing barspins and tailwhips can rotate to their heart's content without getting tangled cables. Though now most famous for their brakes, one of Trickstuff's first products was their Trixer gyro.

Unfortunately, as with most hydraulic gyros, it wasn't the most reliable product and as the company grew and started selling products worldwide, they started to struggle to meet them requests for services and replacement seals. The new version is supposed to be a lot more reliable while still being low friction enough for the demands of slopestyle riders.

Some bikes (such as the YT Play this gyro was built on) have these steerer tube holes drilled in, ready for a gyro. If you don't have them you can drill them in yourself or Trickstuff will also offer a mount that fits under a headset.

This has been a bit of a passion project for Trickstuff and they've apparently gone way over budget in designing it, but they just wanted a product that worked. The original prototype had seven seals and was a bit of a beast, but they've managed to slim it down for the production version while still keeping it reliable. The gyro is designed to run with Shimano or SRAM brakes, and it can also run with Magura but apparently the set up is a bit more tricky. The gyro can also run with DOT fluid or mineral oil

It's a two piece design with the top half in stainless steel and the bottom half anodised aluminum. This is one product that Trickstuff don't make in house in Freiburg, Germany, but they use nearby manufacturers who have advanced enough CNC machines. It has also been tested using a rig developed by the turbo and rocket engine department at the local university.

Get used to seeing this gyro more and more, Trickstuff are hoping the product is so good they can convince enough top slopestyle riders to run it that they get all three spots on the podium in Crankworx Whistler. The gyro will be on sale either in local distributors or direct from Trickstuff in a few months for €189, riders may also have to buy a connection kit that costs €19.90. Yes, that's a lot more than wrapping a long hose underneath your stem, but it's also a lot cleaner and can be spun infinitely in both directions.


Also spotted on the bike was this left hand bottom braket cup called the NoGo that can be stuffed with o-rings to slow down the cranks spinning. Why would you want to do that? Well, if you're throwing big tricks you want to know your cranks are in the same place you left them before you land. The NoGO can take up to five o-rings and will pretty much lock out the crank if desired, this one had two in and stopped turning after less than a rotation when spun hard.

 I’m gonna guess no.... probably won’t help your wheely either.....

 Really happy to see a successful version of this product, no matter how niche.

Fluid Rotary Joints (the industrial version of this) are really tough to engineer at this size (formerly an engineer at rotary joint design firm), and doesn't surprise me they wen;t over budget to find a solution.

 I've used a couple of these in tool design for cooling application. They are a feat of engineering for sure. Especially when the number of inlets and outlets grow!

 @krashDH85: Indeed! We used to design GIANT ones made for offshore hose reels.. 28 individual inlets/outlets for 1" fittings at 4000+ PSI each. I miss that industry, wild stuff.

 yes its those darn tangled cables that are preventing me...

 You spin me right round baby, right round, like a record baby, right round, round, round... oh NVM there’s O-Rings. I don’t spin anymore.

 Seals made from PTFE, O-Rings are stationary, just for compression

 Slopestyle riders just need sram to bring out and AXS level brake then they'd be no friction

 You mean no function?

 They need to make one compatible with my dual crown fork for easier bar spins

 Can someone link a picture of the internals or explain how these work in a manner more than my current understanding; "Magic goes in one end, magic comes out the other"?

 Thank you trickstuff . Both these products cover the two biggest problem areas I have on my Dirtjumper. Really like the crank stopper idea. Always thought it was crazy that you have top riders with big name sponsors sticking grip-ends or electrical tape between their BB’s and cranks.

 i'm right there with you.the price is high on that gyro, but it looks so damn clean. gonna buy both of these for my DJ as a "treat myself" type of thing

 To fit in with the new nerd XC following here on pinkbike, " that NoGo bottom bracket cup sounds like a great product for training the legs up!"
  • + 2
 Are the NOGO bottom brackets available yet? I want to change out the BB on my friends road bike without telling him so when he goes riding he has no idea why his Strava times are high. That will shut him up.
  • + 1
 Yes they are. Please do this and send us some pics / videos
Fantastic prank idea.

 Just flip your riser bars over. Simples.

 Instead of the "No Go", you can just spend 15 bucks and get a Vocal BMX upgrade...

or wrap an old tube around the spindle against the bearing...

 No, this is for MTB. It has to cost a lot of money to do the same thing, otherwise you're a nobody. Remember the old Clio Baccara advert? "Pas assez cher, mon fils"

 A quick glance at the article photo and first thought was steering damper...Ha!

 I would assume more easy (and maybe cheaper) woukd be a wireless system where the reservoir and pump mount directly on a fork or chainstay.

 Do they make a start list for Dual Speed and Style too?

 Dang.... now I am hungry for Gyros.

 I've wanted a EU bottom bracket like that since 34R stopped making their bushing BB's in euro. Good job trick stuff.

 The best brake if you dont want tangled cables is a foot between the seat stay and tire

 Why don't put all that energy and money in a simple reliable, efficient and solid cable actuated brake?
Serious question.
  • + 0
 when have cyclist kept it it simple? oh wait...brakeless!
  • + 2
 Hmm. Because cable disc brakes suck compared to hydraulic.
  • + 2
 Because they already exist. TRP Spire/Spike have pads that engage from both sides, and Paul Klampers are your USA-made boutique option. No doubt there’s an expensive German option too. You can get high quality low friction cable housing, and levers with adjustable leverage ratio. Too bad they all still fail as soon as grit enters the system. The only reason there has even been a market for those products is component makers being slow on the uptake with hydraulic road bike groupsets.

 @alreadyupsidedown: Shimano makes a nice cable operated caliper too, it is what is likely on most of the slope bikes at Crankworx. (Possibly sharpied out for sponsor gratification)
  • + 1
 @BikesBoatsNJeeps: I’ve always wondered how much braking power these guys actually need. Seems like a decent mechanical disc brake would be more than enough to scrub the speed they need to in course. I had a set of avid BB7 on an old hardtail I bought and thise things work surprisingly good.
  • + 1
 @sino428: I do agree with you about bb7. Reliable.
  • + 1
 Cable actuated discs are more than adequate for these guys needs. As a mechanic who used to have to bleed the brakes on a bike with a hydr-gyro, I advise you just get a cable disc. It will work better, and not need bleeding once a week.
  • + 1
 @sino428: not much. BB7s are really a pretty solid option, the only drawback is the frequent pad adjustments. They got a bad rap due to inexperienced owners and shops. I maintain that if you're willing to keep adjusting the pads their not terrible. I did ride a set once a long time ago in Pisgah and had to move the back pad twice in one day to keep the engagement consistent. Plus you could wear the pad to the point where you were jamming the rotor into the caliper body.

 @BikesBoatsNJeeps: we're talking about a slopestyle/dj use here

 @fracasnoxteam: poorly maintained is poorly maintained.
