For that, you can make a cotter-pin lock or similar that locks the steering at your desired angle.Smoke said:I also want it for the classic cargo bike reason of my front wheel trying to flop over when I'm loading the bike.
On SB Cruiser, I used a spring steering damper that was actually for keeping it centered like that when hand-pushing the trike thru a doorway, originally. Worked, sort of, but still flopped around as weight/angle changed going over the doorsill, etc. An actual steering damper like from a MC or similar would probably have worked fine, but never got to try that.
Nowadays, I have a hole drilled thru the steerer and headtube on the side, and a ball-bearing-cotter-pin on a ring and cord that fits in there to lock it straight. I've inspected both steerer and headtube in the year(s?) since then and see no signs of cracking,etc., and given the loads and weigth and braking/etc applied there, I'd call it safe at this point.
I put the pin in whenever I need to hold the wheel straight, including when I'm working on the trike and need to roll it over, or just tip it up a bit to work on a tire/wheel/etc.
As long as the geometry is correct (or rather, "not wrong") you won't have issues like that.I have built one bicycle frame and it didn't have speed wobble at up to 45 mph which was the fastest I ever took it down hill. I don't expect to have a speed wobble with my new frame but if I do the damper should deal with it.
My CrazyBike2 only had an issue with one specific geometry, and a certain speed range, when I happened to change the fork out for a different length one right before a race; I had a number of problems that time around because of that, though I don't recall all the details anymore. Is probably all in one of the DeathRace threads, and the build thread. Other than that time, it hasn't ever had a wobble problem, even at about 40MPH coasting downhill way back when it was first built, and geometry / angles changed several times over the years.
At present the SB Cruiser is using FSA's "The Pig"; has been very sturdy and caused no issues so far.I bought my Viscoset from Jenson USA and it was only a slight upcharge over a Cane Creek series 40 headset so cheap.
