EXA Form KS900i - Rock Solid!

Install

I won't say it's easy - because it requires fiddling to get the cable housing length correct. But any cable operated / internly routed seatpost will face the same problem.

The only complaint is the cable stopper that hooks into the internal actuator. We can't use the cable head - it's too big. So we must use the providad cilinder and screw stopper. I fear the screw may come loose someday and the cable will slip. I just added Loctite - I hope it won't slip

Lever

The provided lever is very basic. It pivots around a pin. It does not provide Shimano's I-Spec EV integration. This is no a deal breaker for most - but my bike has I-Spec levers - and I wanted the clean looks.

I recommend a Shimano dropper lever - for the OEM look. Or this ZTTO oversized roller-bearing lever - for the ultimate smooth operation

Length and Travel

345mm / 100mm travel. I'm 176cm tall with a 81cm inseam. 170mm cranks and 71~72cm seadle height. The dropper seat at the minimum insert limit. So this is a big win IHMO. Minimum weight penalty. And 100mm is perfect for XCM rides.

I recon this only 300g over a carbon fixed post. A very small penalty.
