If this passes for hard conditions: there was a big crash with wheel hitting a drainage cover wall and the whole board flipping. Nothing happened to the whole system. Tons of kilometers on the setup. The yellow hanger kingpin bushings are made from hard plastic, the same that is used for gears in the gear drives.
If you are not a fan of solid polyurethane bushings the original spring+damper combination will work, the standard is kept.
The axles are made from high carbon steel, per request they can be hardened. We do not use any ready-made bolts for axles even if it seems to be the fashion.
Thatās great to hear, so yellow bushing isnāt a wearing part anymore ?
Dampas are great (imo) maybe some wobble on carve after 35kmh on offroad, curious to try the yellow dampas
High carbon steel Axles are different to infinity i guess ? Have some trouble with them on 9ā tyres
Nice to have some good words from you @3DServisas , these ones seems crazy and nothing is better to hear riderās feedback like this.
We tried pretty much every steel you can buy today. All axle pins will soften over time, due to constant small movements. We also tried hardened axles, but they tend to snap and that is worse than a bending axles. Itās all about the fatigue strength and the ability to bend rather than break into two pieces.
Another factor is deck flex. Stiffer decks put more pressure on the trucks (and your bones).
So if these axles bend and arenāt strong enough for this application. Wouldnāt it make sense to increase the diameter? Or do you see trucks as a āconsumableā. And if so whatās the rated change interval?
If the axles are the weakest link why not make them user swapable so the whole hanger isnāt garbageā¦
Why not just make everything thicker and more durable so it lasts? You donāt see a swing arm on a dirt bike needing replaced often. Because itās engineered to handle the loadsā¦
You can design a truck in a way, so that it does not fail over a long time, but then suddenly snaps without a warning. For electric boards we prefer materials that bend before they snap. There is lots of strain on those trucksā¦ Also most mountainboarders want the stuff to be light, so that swing mass is low. Its all about the balance between all the factors to take into account.
I understand riders wants some light parts but here its too much, i wear more trucks than tires.
Infinity is the most durable truck you sell, so if i want some reliable trucks wich one can i buy ?
Its not a trampa truck trial, im only tired to throw money in this parts, there are enough wearing parts in emtb, imo trucks can be during as long as the deck ,ok for maintenance but i canāt throw 1 truck every 5 rides.
I got zero experience with either truck just observing. but the mbs trucks got a stepped axle from 12.6mm to 12mm and they are waay shorter. and if you put the massive 18mm spacer on the inside you got quite abit of leverage on that axle. I presume that is one of the main reason why we see more bent axles on the trampa trucks compared to the MBS. that said the I have no idea what kind of steel they are using. and knowing that would be helpful.
I guess the deck is very stiff and shocks are not absorbed by the deck as much. High total weight and a stiff deck is putting quite some pressure on the axles. It does the same to the knees as well. Personally I prefer more flexible decks for EMTBs, since you ride quite some distances and I like the deck to act as a spring/dampa to swallow all the impacts.
Youre right on this point, i ride a stiff bro, i were on a 17ply holypro who is flexy but uncomfortable for my knees and injuried ankle, i can understand stiff deck canāt absorb vibrations but how about develop good bushings or a truck system for the heavy electric use ? You sell it 1ā¬ per, 1 kilometers on my mtb cost me more than 1 kilometer with my car.
I understand Anyone who ride on road or clean path havenāt this problem but for the people who ride more like your promotion video : jump in the woods, on the rocks and whatever you want, did they replace all their bushings/trucks after every footage ?
You made and develop good stuff but here, for a little piece of plastic shit my truck is garbage.
I buy some expensive parts for reliability and almost free maintenance, that work for everything except this.
When i buy a 10$ ali box for my battery i didnt expect more than my 10$, but for a 130$++ truck its an another thing.
I guess your issues are the holes on your rear hanger. Does the bushing wiggle inside the hole or is it a tight fit? If itās tight you can try to sand the possible sharp edges and rough surfaces a bit with a fine sand paper.
When a hanger starts to eat bushings it`s usually getting worse. I tried brass bushings but they shattered and widened the holes even more. In the end I killed a set of new bushings on every ride, that sucked. A new hanger fixed the problem.
Usually I bend the axle(s) before I get issues with bushings or the holes of the hanger .
Old or new hanger, the problem is the same, bushing fit right, you ride some kilometers and if you didnt change it in the perfect time (20/30km i guess) your truck is dead
Bushing plastic melts on the axle, a new axle is marked after 50kms, axleās holes became oblong after a very short time riding, you win the chance to buy another new truck.
A new hanger fix the problem for some few kilometers, rear or front truck is the same shit, maybe the front bushing last a few more kilometers but nothing normal.
I have tried brass bushing too, bad idea for me
If trampa trucks need to change wheel axles/bushing/hanger axle each ride its a pain.

Just wanted to put done statements right.
