REDSHIFT Dual-Position Seatpost
The patented Dual-Position Bicycle Seatpost is one of the most cost-effective ways of finding more comfort on the bike you already own rather than having to purchase a whole new bike. It allows you to switch between road and aero positions while riding your bike, so you can choose the best riding position at any given part of your ride. A perfect road bike seatpost, mountain bike seatpost, e-bike seatpost, gravel bike seatpost. Revolutionary biking accessory designed for all riders and all bikes.
Seamlessly Lets You Switch Between Road And Aero Positions
Switch between road and aero positions on the fly during your ride, this bike seatpost lets you transform your bike and seamlessly change positions. Choose the best position for every single climb, flat, or descent. The key to riding comfortably is a proper saddle position. Since this bike saddle post allows you to ride with a proper aero bike fit on a standard road bike, you ride faster and more comfortably. Save time, energy, and money from switching from a road bike to an aero bike.
Maintain Proper Leg Extension In Both Positions
This seatpost for bikes is designed to maintain the same pedal-to-saddle length in both positions, ensuring proper leg extension in the road and aero riding positions. The saddle moves forward 50mm, corresponding to approximately 4 degrees of effective seat tube angle change. A simple two-bolt saddle clamp allows infinite saddle tilt adjustment and reliable clamping. 16mm rearward setback (road position).
Compatible With
The bike seatpost is 27.2 mm in diameter by 350 mm in length. Shims (sold separately) can be used to adapt the seatpost to bikes with larger seatpost diameters. The seatpost accepts saddles with standard round 7 mm saddle rails. Weighs 400 g including all hardware.

Ich habe mir diese Stütze jetzt für einen Ironman 70.3 gekauft.Bislang bin ich immer mit Aero-Aufsatz, aber normaler Sattelstütze gefahren.Ich bin gestern dann das erste Mal mit der Redshift Stütze 70 km geradelt und anschließend 15 km gelaufen.In der vorderen Position merkt man einen deutlichen Unterschied: Man kommt viel weiter nach vorne in den Aero-Aufsatz. Das Fahrgefühl wird etwas kippeliger, aber man merkt, dass man ökomischer auf dem Rad unterwegs ist. Im Prinzip sitzt man wie auf einem Triathlon-Rad, da der Winkel des Sattelrohrs quasi ähnlich ist (wird von ca. 73 Grad auf 78 Grad erhöht). Beim Wechsel zum Laufen hatte ich das Gefühl, dass meine Beine nicht so ermüdet waren wie in der normalen Position.Man kann während der Fahr problemlos zwischen den beiden Positionen wechseln: Nach vorne, indem man den Sattel mit der Hand nach vorne zieht und nach hinten, indem man den Sattel mit den Oberschenkeln nach hinten drückt.Der Preis und das Gewicht sind hoch, aber es gibt keine vergleichbare Stütze, mit der man die Sitzposition so schnell und problemlos wechseln kann.

I was expecting this to have some shock absorption, but unfortunately it does not. It is a good saddle post, and does allow for "fine tuning" the saddle in a way most other posts do not allow...but I think it is a bit expensive with no shock absorption. If you are looking for a post to fine tune your saddle placement and do not need shock absorption (...and you are willing to pay the price...) then this post may be what you are looking for.

This thing saved my bad hips/back and let me get on the long gravel rides again without the next day body pain. Travel is smooth and comfort is incredible. I can't recommend this enough.

Just wanted to let you know I received the post and have it installed.Went for the first ride yesterday and it was lovely.We ride smooth and rough gravel 4x/week so this will be getting some good use.I had a full suspension MTB previously, but switched to the fixed frame yrs ago. It's nice to have just enough suspension for what we ride on. Definitely made the ride far more comfortable.A friend of mine has a competitors seatpost. Your design is far superior in looks/esthetics. Also I thinks it's better designed and made. It feels lighter than his seatpost.Great Job. I'm so looking forward to the next ride.

Nutze die Stütze am Endurance Bike mit Lenkeraufsatz. Die vordere Sitzposition passt sehr gut beim Fahren auf den Lenkeraufsätzen, die hintere ist die gleiche wie mit meiner alten Sattelstütze (20 mm setback). Die Stütze ist gut verarbeitet und spielfrei, da klappert auch nichts. Umstellen während der Fahrt ist problemlos möglich.Einziger Nachteil ist das hohe Gewicht mit 400 Gramm.

I wasn’t quite convinced to the quality and effectiveness of this production till I installed it and tried on. First of all , this device never shifts accidentally between 2 positions; however , when you are ready to switch , you can do it easily and on the fly. I am really taken aback how easily I can move between 2 positions without straining, wiggling and etc . Secondly , it servers it’s purpose well. As, I am adjusting my road bike to use it for my first 70.3 distance triathlon, this seat post postions my body in comfortable aero position. When I get off the bike, I feel like my legs are less fatigue and I can transition to running easilier. I now feel more optimistic about my first 70.3.Redshift is a great option for people that are either on budget or don’t want to own seprate road and tri bike.
