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

We manufactured molds for aluminum parts of Rinsten Spring!

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
