Thank you for the kind words!
Building it up, almost all the parts were there. One part that I was not sure on was the stem. I like stems to be shorter than the frame would/should have been built up with in the past and the bars to be wider.
So I felt quite lucky to have found a Joe Murray Velocity Stem in decent shape online. It has 100mm extension, some rise and a very effective brake cable routing.
It fits me and the bike.
As I exchanged a few emails with Paul Brodie I also attached a photo for him to have a look at my bike. He commended the overall proportions, but also pointed out: "That stem is a terrible mismatch!".
Having now read his book, I know what he means.
TBG or later Kona did not do that great as the only raw material supplier and distributor for Brodie Research. The conflict ended in a lawsuit.
Therefore this stem has to go. However I do struggle to find a replacement that works.
I want to put some modern bars on there. By that mean 38mm rise Reverse Base bars with 25.4mm diameter. Just because.
Right now there is a set of Ritchey WCS Rizer bars on there. Which works ok, but they are just a touch too narrow and keeping them would be too easy.
So for that 38mm set of bars I need a 0° stem, which obviously looks much better. With 7° of backsweep I will need to twist those bars back towards me to get a comfortable hand position. But that is a bonus, as this will allow me to use it with a longer stem.
I eye-balled that a 0° 120mm stem would be ideal. But not without some sort of brake routing.
I found a 3ttt stem on Ebay that should work. Unfortunately the brake cable routing is just a hole through the extending tube with a constant diameter from top to bottom and the bars that I want to fit, do not to fit, as the 'rise' part of the bars is too wide.
That stem will be modified.
This is the first try.
