Iurii Kopytsia about investigation

Hello, Dear Friends!
We bring our apologies that we have not been in touch for almost a month. This month was rather challenging for us. We did not know the answer to many of your questions because the investigation was in progress. And we did not know what we would discover as a result of the investigation. But now we have full information, and we can share it with you.
We have completed the investigation. We did a lot of different tests with more than 200 springs and none broke down. We conducted the investigation with the help of specialists and scientists from 3 institutes: G.S. Pisarenko Institute for Problems of Strength of the National Academy of Sciences of Ukraine, E.O. Paton Electric Welding Institute of the National Academy of Sciences of Ukraine, National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute". These scientists helped our engineers find the cause of the breakdown and find a solution to this problem. A material defect was not detected. So, after the tests and analyses we found out that there was a defect in a small portion of the produced springs. Less than 1%, which was due to a slight violation of the heat treatment process.
Regarding the feedback from the backers whose springs broke down, we also managed to find out,that when this happened, they just heard the sound of "crack", stopped, took off the spring, set the saddle back and continued on their journey. No one was hurt and no one fell from the bicycle.
We contacted the backers who already use the springs. Almost all of them said that they will continue to use springs. Some decided not to use the spring until we send them new ones. People of different weights, on different roads and with different settings, use Rinsten Spring and they are satisfied with their springs.
Despite the fact, that the percentage of breakage is very small, we decided to make an entirely new batch, which we will send to our backers. Of course, we understand that this is another delay, but in any case we will not send Rinsten Spring even with such small probability of breakage. Our reputation and honest name is the most valuable for us.
You believed us when you supported our project for the first time, now we ask you to support us again. But, this time not with money, but with patience. New batch will be ready in August. And we will start to send your orders immediately after it will be ready.
We are working now on refunds for those, who prefer to receive it - this is just the matter of time as the funds have been invested in production. So please rest assured, that the refund will follow - albeit maybe not right after the request, but with some reasonable wait time. We will regularly be in direct contact with all who request the refund.
On the other hand, we are full of appreciation and gratitude for your support, aired in comments and private messages alike. We, too, believe, that safety is above all and value your understanding on more time needed to produce a product with high level of reliability. We are, too, deeply concerned with the situation. We are working hard with engineers to improve the metal alloy to enhance the durability of the spring.
Our customer service agent will be in touch with any backers who experience any kind of breakage to further investigate and replace the product right away.
Once again, thank you for your trust, words of support and patience.
Together we will make this part as safe as physically possible.

I’m, Iurii Kopytsia, the inventor of Rinsten Spring, apologizing for the long silence.
But, we had a reasons for that.
Several springs were broken at our backers. Fortunately, no one was hurt!
I temporarily suspend the sending of the springs, until I find out the reasons.
The whole party will be returned to the factory and will take all possible measures to avoid this incident in the future.
Our experts in the field of strength of metal, are now actively working on clarifying the causes of the failure.
I hope that you accept this news with understanding. This is production. These are complex processes.
We will send all your orders, but only after I will sure of the quality of the product.
Also, we ask those who have already received springs to pay attention to the fact that the spring can bursts.
And be careful of using the spring.
In case of a breakdown, please contact us immediately: email@example.com
Once again I want to emphasize that this is a temporary delay.
And we'll start sending out the springs as soon as we can fix the problem.

Whats new in Rinsten?

To our deep regret, before the Chinese New Year the factory managed to paint only 350 pieces Rinsten Spring, and only in a black matte color. We are very sorry that we can not send all the pre-orders. But, the factory with which we began to cooperate was the only one that promised us to paint at least some quantity of Rinsten Spring before the Chinese New Year.
But, since we have ready 350 pieces of matte black color, we decided to send this quantity by random method in different countries. First of all, we will be able to test the sending service, and secondly, we will fulfill our obligations to a part of our backers.
The rest Rinsten Springs will be painted after the Chinese New Year.
But, we have and what to boast about!
As we said earlier, we were forced to change the paint factory, which is why there was a delay in the painting of the whole lot. They were able to send only samples of colored Rinsten Springs.
In addition, we changed the design of the engraving a little on the springs. Now the inscriptions on the Rinsten Springs have become more elegant.
And we'd love to share pics with you.
Also we want to show you LED Safety Caps.
We are working with 4 different factories to production this accessories.
They are shining bright in the dark, thats mean that you can ride bikes more safety with them.
Friends, hope for your understanding. In this situation, we did everything that was in our power. And we will continue to work harder after Chinese New Year. We will fulfill our obligations to you and continue the business that we started thanks to your support.
We would like to thank you All once again for your massive support and patience!
