I confirm. Intgra is piece of shit. Basically bad design. Really bad. Same design flaw is shared by Yep Components integral version. As far as both products are great in terms of operation they both are piece of crap in terms of how integral actuator is designed (by idiots). Basically cable is freely attached to the bottom of the actuator and IT IS NOT secured in any way. Entirely relying on cable tension. Guess what? Id gets loose all the freacking time because of the vibration and lack of secure attachment to the bootm of the post. It works on some bikes and it will never work on others. Ever. And they will not refund you as they will say it’s working. Not it’s **** not working assholes! You made basic deign mistake and that is a **** fact! (To all KS Lev team). So to sum it up my experience with ALL major internally routed seatposts (if you have freaky frame like me).
1. Do not bother with internally routed posts. Just pain in the ass. Seriously not worth it just to have 40cm of cable hidden.
2. or only buy Reverb Stalth as it operates on oil.
3. Cable actuated posts are – cable actuated. If you ever had problems with cable friction in your gears (heavy shifting) you will know what I mean. My take on this is – cables sucks. If I could I would replace all wires with mineral oil.
Seriously, avoid KS LEv and Yep Components internally routed products. They are expensive piece of shit due to basic design flaw with actuator attachment. Avoid at all costs. They will not consider it under warranty and they will not refund. Stay away.
Overall. It is amazing form me that so many years, so much money they cost and yes, thy help a lot, but simply thy are still freacking average working products with lots of gimmicky problems.
