I naively thought getting a KH rail adapter and Primo "The Rod" seatpost
would be an improvement on my current miyata seatpost and brake mount
barend. How silly I was!
The first thing I noticed is that the Primo seatpost weighs a ton!
This upgrade has a large weight penalty. Not only that, the rails of the
adapter don't sit squarely in the slots of the seatpost. Not sure if
this is an intentional part of the adapter's design, but this problem
goes away once you tighen the seatpost's clamping bolts up.
Next and most annoying is the fact that when bolted to a standard Miyata
seat base there is virtually no adjustment possible in positioning the
brake lever on the adapter's mounting post. There is a ridge of plastic
underneath where the brake lever goes, so you cannot move the lever
towards the front of the mounting post without hitting the seatbase. If
only the mounting post had been made parallel to the seatbase this
problem would have been eliminated and also would have allowed a large
range of adjustment. The best I could do ended up having my brake lever
extender hitting the front seat bumper, before the brake pads even hit
the rim. Seems like a particularly goofy design to me. Ok maybe I'm not
using a CF seatbase and a HS-33 brake (I've got an old HS-11) but surely
these things could have been taken into account when the rail adapter
was designed!
Worst upgrade ever.
