Steve, in response to your pics on FB, you do know that you can get a reverse pattern drum from Bruce?
It would enable you to utilise a more conventional linkage set up which, in turn, would allow you to experiment with different lengths on the levers.
TTI boxes have a very short through, shame you’re not currently capitalising on that…
Yes, I do, but I didn't know that when I built the bike in 2014 ish. Which is when I made the linkage.
It was simple and easy to do with parts I had at the time. And it worked absolutely fine for years. Light and positive gearchange.
Things have changed. Mostly me. I will keep working on the idea of muscle stretching. I think that may be where a significant part of the problem comes from. I have two pairs of boots, things are better with the older and slightly larger and more flexible pair.
The other approach would be just a reversed lever, no linkage, and move the footrest forward. I have tried just putting a toe piece on the lever I have, 120mm centres, very light, short throw, absolutely great for neutral selection, but of course, out of reach of my foot.
Much lighter than any linkage. But I would need a longer lever. Molnar does one he says you can go to 130mm centres with, so you would be giving back a little for the reach. But with my little feet I would still need to put the footrest where the swinging arm spindle is, like ummmm, a Seeley!
Then maybe I would end up trimming fairings, relocating brackets, catch tanks, it goes on and on.....
