48 hours left and Paris - Roubaix bonus!
almost 2 years ago – Tue, Apr 18, 2017 at 01:56:42 PM

This is it! Here we stand!  

And we are so close to finish, but still have 48 hours and OUR WONDERFUL BACKERS. Our Kickstarter campaign will be closing on Thursday April 20 at 10AM. 

The Rinsten Spring community continues to amaze us. This time around, you’ve carried our project to over $118 thousand from more than 2,250 backers. So we are so exciting to see, what we done, and how much you like it. As we start it, we will continue in the same vein - THANK YOU, THANK YOU, THANK YOU. AGAIN AND AGAIN AND AGAIN. 


 We had a lot of questions about how does it feel to ride on Rinsten. We got a good answer for you - David Birkinshaw, who participated in Paris - Roubaix at 9 of April, write a first-person story, about his experience with Rinsten Spring. 

"Two years ago I entered the Paris to Roubaix amateur ride. For those not in the know, the ride is 172km through the French countryside, punctuated by some 60km of cobbles, which vary (easy to hard) from grade 2 to 5. To be frank, I hadn’t really trained for this one, and the ride took some 10 hours, meaning I missed the legendary cycle round the velo track at the end. Also, the 172km distance meant it was a living hell for about the last 70k!"

"On arrival, I think first impressions were that it was the simplest of things. The springs match the seat post perfectly at the bottom, and at the top the seat rails can be attached with a very simple metal plate."

"And the first set of cobbles proved to be an easy match. The spring responded well, absorbing the major shocks of the cobbles with ease. I was able to stay on the saddle, rest my weight in full, the spring acting as a good shock absorber."

At that time, your credit cards will be charged – a process that may take a few days. This is a reminder to make sure that the credit card you have used has enough credit to fulfill your pledge and is still active (has not been cancelled). We want to make sure that everyone who signed up for a Rinsten Spring receives one. 

 We will also be receiving contact emails for each of our Backers through Kickstarter. After some time of ending campaign, we'll be emailing you directly with colour selection, shipping address requests and other updates. 

 What’s more? For all our favorite backers we found project, that will help to make your bike more safe. We really LOVE it, and sure, you will feel same:

Stretch Goal Unlocked: Bag Holder !
almost 2 years ago – Thu, Apr 06, 2017 at 02:28:31 PM

What a day, WHAT A LOVELY DAY !

This unbelievable! 500% sounds like we overcame the sky's limit! 

Rinsten Team did it? No, all of you did it! So much LOVE you give us, so THANK YOU.


By reaching $75,000 you’ve given us the ability to add the clip-on bag holder to Rinsten Spring! In private messages, we often get questions about how to hang bags or other devices without impacting Rinsten Spring.

And this is the Rinsten Spring clip-on Bag Holder:



And we’ve got more goals on the horizon. We’re more than grateful, but humbled by all the support, feedbacks and love you share with us. Big and warm THANK YOU!


There are some changes...

 On the 2nd of April the long term test of Rinsten Spring came to an end, and the results showed, that Rinsten Spring can withstand riders weighing up to 220 kg. The tests showed that the strength to produce a small amount of steel deformation can start only after 404 kg weight. That is why Rinsten Spring is suitable for everyone weighing up to 220 kg (485 lbs)

Until next time

Warmly, Rinsten Team

It's TIME to share projects WE LOVE !
