BEAST Components RISER BAR 15 2.0 Lenker Carbon, UD-Finish, 31.8mm - 780mm, Schwarz


Unser Riser Bar ist nicht nur stabiler als die meisten seiner Konkurrenz, sondern auch merklich bequemer. Er dämpft durch die Verwendung von hochwertigsten Materialen und seinem ausgetüftelten Carbon Lageplan deutlich besser kleine Schläge und Vibrationen ab. Gleichzeitig ist er steif genug, um dir das richtige Feedback zu geben und sehr präzise zu manövrieren. 

„Der Riser Bar [2.0]-Carbonlenker von Beast Components ist wie gemacht für die härtesten Enduro-Strecken und den Downhill-Einsatz – und er hält dort noch stand, wo manch andere Carbonlenker scheitern. Die Bremsschellen vieler Bremsen sind unrund und haben nur eine minimale Auflagefläche. Das führt zu einer ungünstige Lastverteilung und kann an Carbonlenkern Einkerbungen hinterlassen. Der Riser Bar [2.0] beugt dem mit einem speziellen Polyester-Prepreg-Fleece und einer lastgerechten Carbonlagenstruktur vor. Er hält mit bis zu 6 Nm ein doppelt so hohes Anzugsdrehmoment aus wie ein gewöhnlicher Carbonlenker. Dadurch kann man auf dem Trail die Bremsen einfach mit einem Multitool anziehen, ohne dabei Gefahr zu laufen, den Lenker zu beschädigen. Trotz der hohen Stabilität bleibt der Riser Bar je nach Modell mit einem Gewicht von 174 bis 234 g ein absolutes Leichtgewicht. Er wird zu 100 % in Deutschland handgefertigt und verleiht mit seinem perfekten Finish dem Look eines jeden Bikes Pluspunkte. Er kommt in vielen unterschiedlichen Breiten, mit 31,8mm Durchmesser und mit 15mm Rise. So sollte für beinahe jeden Biker der passende Riser Bar zu finden sein."

WARUM DIE ÜBERARBEITUNG DER LENKER NÖTIG WAR
Einige neu auf den Markt gekommene Bremsen und Schellen, wie unter anderem die von Shimano und SRAM, weisen für Carbon- und Leichtbaulenker ein sehr unvorteilhaftes Klemmdesign auf. Die Schellen sind nicht rund und die Auflagefläche ist minimal. Lasten werden so nicht mehr flächig auf den Klemmbereich des Lenkers verteilt, sondern punktuell eingeleitet. Dieses Quetsch-Prinzip der neuartigen Bremsklemmungen ist pures Gift für jegliche Carbon Struktur.
Man muss kein Ingenieur sein, um zu verstehen, dass die auf den Lenker treffenden Kräfte so nicht belastungsgerecht verteilt werden können.

Durch unsere enge Zusammenarbeit mit dem auf Hightech-Leichtbau spezialisierten Entwicklungsdienstleister Realize Engineering war es kein Problem die gängigsten Bremsen auf dem Markt einmal genauer unter die Lupe zu nehmen. Die Ergebnisse waren besorgniserregend.

Wir haben mit den betreffenden Herstellern gesprochen und unsere Kunden darüber informiert und sensibilisiert. Wir haben überlegt die betreffenden Bremsen und Schellen für unsere MTB Lenker zu sperren. Am Ende haben wir jedoch festgestellt, dass wir mit den neuen Klemmdesigns leben müssen und uns deshalb auf die Suche nach der bestmöglichen Lösung gemacht.

DAS IST NEU
Um eine noch höhere Sicherheit und Dauerfestigkeit zu erzielen, haben wir uns noch einmal den Aufbau des Lenkers im Klemmbereich der Bremshebel angesehen. Neben dem neuen noch ausgefeilteren und belastungsorientierteren Lagenaufbau und einer sehr aufwendigen Faseranordnung, verwenden wir für unsere Riser und Flat Bars nun ein spezielles Polyester-Prepreg-Vlies.

Das Polyester-Prepreg-Vlies hat folgende positive Eigenschaften für uns: Es besitzt eine hohe Festigkeit und Kriechfestigkeit und weist gleichzeitig eine geringe Gleitreibung und Gleitverschleiß auf. Wir setzten es ausschließlich im Klemmbereich der Bremsen ein. So werden punktuelle Lasten deutlich besser absorbiert und gleichmäßig auf den Lenker verteilt. Eindrücke der Klemmschellen werden minimiert und die darunter befindlichen Carbonlagen geschützt.

Es ist gewissermaßen ein Sicherheitspuffer zur druckempfindlichen Carbon-Oberfläche und ermöglicht dir die freie Auswahl deiner gewünschten Bremse und die Verwendung eines höheren Anzugsmoments.

SICHERHEIT GEHT VOR
Das von uns verwendete Polyester-Prepreg-Vlies fügt sich optisch dezent in das Erscheinungsbild des Lenkers ein, durchbricht optisch allerdings die Faserstruktur. Sind Armaturen und Griffe verbaut, fällt der neue Klemmbereich nicht weiter auf. Wir nehmen die optische Veränderung und das Mehrgewicht von ca. 20 g im Vergleich zu den alten Modellen in Kauf, denn es liefert euch wesentlich mehr Sicherheit. Und darauf sollte es beim MTB ja wohl ankommen.

Um das neue Sicherheitsniveau zu bestätigen, haben wir unsere Testverfahren noch einmal verschärft. Dabei wurden zusätzlich zu dem von uns, entsprechend des Multi Load Test des Zedler Instituts, abgebildeten Testzyklus realitätsnähere Bedienungen hinzugefügt. Dies beinhaltet z.B. das fünfmalige Verdrehen der Bremsschellen bei einem Anzugsmoment von 1,5 Nm und das zehnmalige Anziehen und Lösen der Bremsschellen mit einem Anzugsmoment von 4Nm vor dem eigentlichen Test.

Keeps my wild child busy!
Color: Orange
*UPDATE 1/10/26* Does my pup love it? Yes. 5 stars for that. His big thing is just holding it in his mouth though, and laying down with it. Then he will put it down, and as soon as it rolls away he gets up and grabs it again. He definitely requires attention from his humans when it’s turned on…kind of defeats the purpose of why I bought it! He’s a needy boy, that’s for sure, so it’s not the toy’s fault. Two improvements I’d love to see though, are 1) the ability to turn off that yappy bark. I think my dog is more excited about it moving and not so much the yapping. Not that it’s bad, but my boy doesn’t bark much so I’m used to a quieter household. And 2) when removing the base for powering off, there should be a sensor so it doesn’t keep spinning in the socket, occasionally slipping out and hitting the floor. I worry about it breaking due to this. This thing arrived today and we couldn’t wait till Christmas to give it to our high play drive Australian Shepherd. It’s been barely above zero for weeks with no end in sight, and I have cold weather asthma so I really try to limit my exposure to the elements. Needless to say, my dog has been B O R E D. He truly craves interactive play with his humans, but last week I bought a cheap r/c cat toy that really caught his attention. So I splurged on this toy and so far, it’s AWESOME. He can’t control himself when the rope starts spinning. He pounces on it and it goes spinning off and around. He keeps picking it up thinking it’ll stop, but it keeps going. After 5 minutes of play he was acting completely gassed, but he just can’t resist it, as he put it down to get a drink of water and it started spinning again. Forget the water, I need that toy! As long as this thing can handle the teeth, slobber, dirt and grime, I’ll be a repeat customer!

My dog loves it...but needs charging four, five times a day. You really need 2 for full-time play
Color: Blue
My dog loves this toy. The first time she saw it and it started rolling, bounding, and waving the ropes around...she was barking at it, chasing it, grabbing it, jumping all over the place. There is no other toy she has that she will leave this for. And...that's part of the problem. I have to take this away from her three, four, five times a day to recharge it. The charge barely lasts an hour and the toy is dead. And it takes over an hour to charge it all the way up. Which means she plays with it less than it spends charging. That's not ideal. The product page and manual that comes with the toy says there is a 10-minute play period followed by a 30-minute interval to let the dog cool down...not get overly stimulated. I have never seen a cool-down period. I don't know if it's because the dog plays with it, shakes it around, tosses it and chases it, etc., etc., etc. constantly...but it just keep going until the battery is dead. I wish it did have a cool-down period. She likes playing with the ropes and rolling it around herself even after the battery dies, so if there was a cool-down, maybe it wouldn't need to be charged many times a day. Once it's charged and she sees me putting it back together, she gets very excited and starts jumping up and trying to grab it. Our corgi reduces most rope toys to threads in a day or less, and this one has held up surprisingly well against her super-chewing habits. The material the ball part is made of is very durable (we have a couple other toys with the same type of shell) and she's chewed on them all a lot without any damage. The toy keeps her entertained and happy...when it's not on the charger. I wish it was a good-enough value for the money to be able to justify buying two of them so I could have one charging while she was playing with the other. ================= I'm adding 1 star, because the company customer service is outstanding. They emailed me about my concerns vis-a-vis the short battery life, and it seemed that they really listened and cared about my input. I don't know what, if anything, can be done to extend the battery life given that it's spinning some substantial pieces of rope around, but I think they'll do as much as they can. In the meantime, my dog's love for this toy has not diminished in the least. She still gets very excited when she sees me starting to put it together after it's done charging, and she ignores everything else (sometimes even offers of treats) to play with it. I have a second one now, and I can almost keep them going full-time, but the few minutes every couple hours when both of them are on the charger is probably good for her anyway...she'd probably be over-stimulated if she had one of these to chase non-stop. Summary: Great toy, lots of fun, my dog loves it. However, you really need two the way things are right now unless you are okay with your dog being able to play less than half the time.

My German Shepherd loves it!
Color: Blue
My GSD loves this thing! It bounces and the rope thing wiggles and spins. She is supervised while playing with it. The charge lasts about an hour or so. The only thing that is a little annoying is it makes a little barking sound on one of the settings. It screws apart for easy access. So far she's not been able to destroy it but she has opened it so definitely supervise playing time. It rolls around and bounces on the carpet and on the hard floor it jumps a little bit. Can be loud on hard floors. It's a soft rubber kinda texture that is easy to rinse off and clean. Probably best for indoor use or use on decks or patios. Keeps her very engaged and I have a blast watching her and playing with her with this thing!

Not for chewers
Color: Blue, Color: Blue
Ok, first off, my dog absolutely loved this toy. Still loves it. However: it only took him two days to utterly destroy the part that made it interactive. The rope fastened to the small interior plastic part that is moved by the rechargeable motor was too soft for him and he chewed it off right at the root, where it attached. This makes the toy immobile. It still makes noise and vibrates, but it no longer leaps and bounces. So now he carries it around while it vibrates inside his jaws and I watch his ears jiggle and make sure he doesn’t eat the whole thing. Please note: this is a medium sized Corgi, not a huge dog like a Rottweiler. There is no way to add a new rope to that interior plastic piece: they are made as an inseparable unit. You have to buy the full replacement set which includes a new cover. I would recommend this toy for someone whose dog is NOT a chewer. For someone whose dog loves to chase, and is excited by noise. If those pesky squirrels chattering outside really get to him, this toy will be his new favorite. But if your dog likes to chew and has more than two teeth in his mouth, this toy is not a great choice and you should spend your money on something that will last a bit longer. It’s not a good value for the money. I bought this original toy and a replacement cover+rope set, and I’m not going to give him the replacement cover for a long, long time. I can’t afford to replace these every few days! Thankfully he still loves the toy despite the fact that it doesn’t run away from him, and hasn’t tried to eat the foam covering, so it’s just the softness of the rope I am disappointed in. But I’m not going to buy this again and can’t recommend it highly, based on my experience, despite my dog loving it and the joy I get watching his ears shake as he trots around the house holding onto this expensive mouth vibrator.
