Design Changes & Schedule Update

Posted by Redshift Sports (Creator)

Greetings Backers! 

It's been a hectic end to the summer here - we've been hammering away on design changes, testing, and manufacturing logistics, and we're overdue for an update. 

Design Updates

We've made a number of important design changes to the seatpost based on testing and rider input. Some of the changes were planned before the Kickstarter, and some were based on valuable feedback that we received from backers during and after the campaign. 

2 > 1 - The most visually obvious change is the switch to a 2-bolt saddle clamp from the previous side-address one-bolt design. User testing showed that it was difficult for riders to achieve the high bolt torque required to prevent slippage, especially using a small multi-tool that riders often carry.

The switch to a bombproof 2-bolt clamp system required a complete overhaul of the rear linkage of the post, as well as additional testing to ensure that the revised mechanism could withstand the high forces that are applied to the saddle. But we think the benefits are worth the extra effort:

  • Bombproof tilt adjustment - the two bolt design virtually eliminates the possibility of slippage, and saddle tilt can be precisely adjusted very easily.
  • Lower torques - the torque specs for the bolts are around 6 N-m (compared to 14 N-m for the side-address design), meaning that trail-side adjustments are easy to do with a standard multi-tool.
  • Lower profile appearance - the two-bolt design is much lower profile than the one-bolt design, resulting in a sleeker look and better aerodynamics.

The Missing Link(age) - Under the hood, we updated the connection between the lower linkage and the spring plunger to include a separate short linkage. The previous cam connection was wearing prematurely in high-contamination (aka "muddy") conditions. The addition of the plunger linkage eliminates the wear point and makes the suspension action smoother and more responsive.

Tiny linkage. Big deal.

Fend for Yourself - Last but not least, based on our backers' feedback, we'll be including a removable fender with every seatpost. For those of you who frequent the aforementioned "high-contamination" environments, the fender is a great way to extend the duration between service/cleaning intervals and keep the seatpost running as smooth as possible. We'll have more details and photos of the fenders in our next updates.

May we suggest a side of fender with that mud pie?

Schedule Update

As you may have guessed, these design changes and associated prototyping/re-testing have delayed our production and shipping schedule. We had hoped to have the seatposts in your hands by the end of the year, but we're now targeting early 2019 instead.

Our mission here at Redshift is to produce the highest-quality components, and sometimes that means delaying shipment of a product in order to make it live up to your (and our) high expectations. Thank you so much for your patience and support - none of this would be possible without our backers, and we love that we get to share our journey with all of you.

As always, if you have any questions or comments, please feel free to reach out via the Kickstarter comments, Facebook, or via email at

      I'd like you to update my shipping address because am gonna move in the beginning of January 2019. How can I let you know my new address?

    3. Redshift Sports 3-time creator on

      @Indra - you bet. We will continue to provide schedule updates so everyone knows when to expect shipping. Thanks

    4. Indra Rochadi on

      Please update when it will be shipped. Thanks a bunch.

    5. Jan Sapper on

      Keep it up with in depth updates! No delay is a problem as long as you show progress and keep us informed.

      @Godlyman Ded - We really wanted to get these in your hands before the end of the year, but ultimately, we think it's more important to perfect the product, even if it means delaying the ship date.

    7. Godlyman Ded on

      So now because of the resign, the delivery date got moved to "early 2019" which can mean from 1- 3 months ... I cannot say I'm happy about that ... -_-

      @isaac - The weight of the seatpost is the same without the fender. The fender weight is TBD but it will be very light.

    9. Isaac Tait on

      With the newly designed upgrades what is the current weight of the seat post w/ and w/out the fender?

      @Matthew - We do offer early stem shipping in the survey we sent you if you'd prefer to have the stem sooner. If you need help with the survey, please email us directly at

    11. Matthew Johnson on

      I ordered the seat post and the stem. I am correct assuming the stem should ship soon? Hopefully I don't have to wait for when the sestpost is shipping to get my suspension stem. Thanks!

    12. Redshift Sports 3-time creator on

      @Bernard - thanks so much. Appreciate it.

    13. Redshift Sports 3-time creator on

      @Matthew - the new saddle clamp will be compatible with oval rails. If we can accommodate both round and oval in the same clamp we will provide everyone who ordered the oval upgrade a refund but it still might require an additional part. We will let everyone know as soon as that is finalized.

      @Tarunn - unfortunately, this is not something we are planning to provide. There are telescopic posts but I am not aware of any in 30.9mm. Thanks

      I like the brass bearings. Those will definately contribute to the suspension‘s life span. And that‘s worth waiting a few months.

      Ok, so you've changed the whole saddle rail setup. Having bikes equipped with both designs on various seat poles, the two-bolt is certainly superior.
      However, how does this affect those of us who purchased the oval rail clamps?
      I presume with the redesign that the new clamp is suitable for both round and oval rails.

    17. tarunn on

      Hi guys it would be great if you could provide 30.9 mm telescopic shims for folding bikes. 500mm length. It would be great. Thanks

      @Tim - Funny, the creator of the Nexride saddle is in the office right next to us! I understand that it's not ideal to have an exposed bolt in that region with the Nexride. When you receive the seatpost and install it to your preferred tilt angle, we can send you a set of custom bolt lengths that are appropriate for your setup - that way, the ends of the bolts won't protrude beyond the top of the saddle clamp. Overall though, I think the switch to a 2-bolt clamp will be beneficial since the prospect of saddle slippage with the Nexride saddle is a pretty painful possibility.

      @Robert - Glad you agree with the design direction! Send us a message at and we'll get you sorted.

      @Richard - we're targeting late January or early February right now and will have a more definite timeline within the next month or two. It's tough for us to miss the holiday shipping window, but hopefully the recipient will appreciate the more refined seatpost.

      When exactly is early 2019? I ordered this as a holiday present

    20. Robert Etzler on

      I prefer the standard 2 bolt rail clamp for it's strength, besides I pretty much use Thomson seat posts anyway on my Selle Anatomica saddles. For those of use who ordered a stem with the seat post, a nice gesture on your part would be send us the stem now without additional shipping costs. I would like to be testing it out before winter rolls in.

    21. Tim Tucker on

      The rationale makes sense, but I'll admit I'm a little disappointed by the switch for the saddle mount.
      I ride with a Nexride noseless saddle, so the area in front of the saddle is exposed while riding. With the original design, it was a nice smooth curve with fewer exposed parts and less potential for danger if I were to slip forward off the saddle. The new design means I'll have an exposed bolt sticking straight up.
