Dear @rinsten_community, our backers and fans,

First of all, we highly appreciate your patience and support and we're doing our best to ship your Rinsten springs as fast as it is possible. We would like to say again how sincerely we are sorry for having kept all of you waiting. 

All our team is working hard to make a perfect product for you and deliver it in the shortest time. This is a project where everyone’s passion is contributed in order to create something special, and we are looking forward to delivering the final product to you, our dearest Backers.

As you know, your safety and health are the first priorities for us. So, we keep testing our Rinsten spring in different ways to be sure you can use it with all confidence.

On the testing stand in the lab, each spring of the testing batch was loaded with over 300 kg (660 lbs) weight and all of them successfully passed the test without any deformation! 

Please have a look at the pictures of testing below.



Also we've tested Rinsten spring at the factory in the different ways. We used the same weight, over 300 kg (660 lbs), to bend the spring down to the bottom and it kept its perfect shape and position without any damage done. Great results, good job!

We used over 300 kg weight...

And bend it!

That's all for now, however, some amazing news are to be announced very shortly. We'll be sure to keep everyone updated and share our passion and love with you.

Thank you for being supportive and patient.

With love,

Your Rinsten Team

Dear Backers,

We will never stop to say thank you for your support and your great patience, we love you all.

We are transparent with you and continue inform you about production news.

Our work on finalizing all steps for producing aluminum spring parts were finaly approved.

 We tested the material for quality from different manufacturers and went through different materials and we are happy to announce that had found aluminum better, which is 9% stronger and 4% lighter. Manufacture already works on producing aluminium parts.

 Thanks of your comments you directed us to a great idea to make engraving on each mount plate.

 So, each plate in a set will be engraved as: the top plate will have sign «Rinsten» , the middle plate at its sides - «Rinsten», and the bottom plate will be engraved as «Spring».




This will add aesthetics to your Rinsten spring and help you easily and quickly install it on your bicycle in the correct way.

 We make all our efforts to deliver your orders as soon as possible.

And we'll keep everyone informed on the progress as we continue to work through production.

Thank you for waiting, support and your patience.

Your Rinsten Team

Hello dear backers, 

Thank you once again for supporting our project and your great patience.

Our team has spent all summer in China producing and testing the samples of Rinsten Spring with our new production partner, as it was very important to have our presence on the site and make sure everything is under our control.

We tested different steel grades and types of its hardening and eventually, came up with the solution to use the steel of Grade 60SI2M which is more durable. Numerous tests gave excellent results. 

Your safety and satisfaction with Rinsten Spring are our priority, although it took more time than we expected to find suitable materials and a production partner. 


We love you very much, our dearest backers, and want to provide you with the best product!

See a picture and a video from the testing lab.


We make all our efforts to deliver your orders as soon as possible.

Let’s keep fingers crossed!

We'll be sure to keep everyone informed on the progress as we continue to work through production.

Keep an eye on our updates!

Thank you for waiting and your patience.

We are doing our best to make the Rinsten Spring perfect!!

Dear backers,

Thank you for making our project a reality and your great patience in waiting to get the product in hands.

As we were posting in our comments, we spent a few weeks in China collaborating with our prospective production partners. We are very demanding on the quality of the Rinsten Spring and willing to deliver you the best of the best.

We requested to produce the prototype at a number of factories to find the best production partner and get that quality of Rinsten Spring, which we wanted to be when promised you a Lifetime Warranty. However, none of them satisfied us.

The other thing, which made us look for another production partner is a load of orders received from you.

So we had to go on and on in search of the production site with the suitable capacity to fulfill the quality and quantity requirements and eventually we did it!!!

We agree that it took much more time than we expected and caused the delay in production and shipping to your homes consequently.

Our team is still in China working hard to manage all the aspects of production according to our vision in collaboration with our new production partner. 

There is a great news for those of you who ordered LED safety cups. Finally, we got them done perfectly! Here are some pictures and video of LED safety cups prototypes.

You will definitely love them.

We are totally focused on the production and doing our best to make the Rinsten Spring perfect for you and looking forward to sending it to you as soon as possible.

Sincerely yours,

Rinsten Team
