Latest Updates from Our Project:

Real quality warranty

Dear Backers! 

Thank you very much for your support and patience! 

We understand that for some, to start production seems like a very simple and quick process. Unfortunately, it's not right. Searching for reliable partners and conducting numerous tests took a very long time. 

During the test period, we encountered several problems. One of them was the propensity of metal to corrosion. To protect Rinsten Spring, we decided to zincify all springs. We want you to enjoy riding your bike with Rinsten Spring for a lot of years. Zinc-plated springs will not allow the metal to rust and will make the springs more resistant to any weather conditions.


To our regret, the bicycling season in the northern hemisphere has already finished. We really sorry for the season without Rinsten Spring. We decided to support our backers and extend "the 30-days money back warranty". We give you an opportunity to test Rinsten Spring after the start of next season in your country. The return guarantee will be valid until May 1, 2018.



We sincerely thank you for supporting our project. 

Best Regards,

Your Rinsten Team

Dear friends! 

We sincerely thank you for supporting our project! 

We are happy to see you among our like-minded backers. Today, we are pleased to inform you of another great news!

We manufactured molds for production aluminum parts of Rinsten Spring.



In molds we produced the first serial samples of plates and Safety Caps from high-quality aluminum.

Top, mid and bottom plates will connect and securely hold your spring and saddle.


Safety Caps cover the end of the spring and protect you from sharp endings. Also, Safety Caps restrict the movement of plates and prevent the saddle from falling out.



We plan to send Rinsten Spring before the end of this year. 

Please, fallow our updates to be aware of our progress.

Thank you for waiting, support and your patience!

Best Regards,

Your team Rinsten

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...
We used over 300 kg weight...


And bend it!
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
