I tend to oversteer in those situations. *The bike feels like it pulls

Anyone have opinions on how I can "smooth out" (or slow down, or make

Talk to IF. I didn't see a geometry table for the CJ. Steep head
angles (common in track bikes) need less fork rake (offset) to have
the same trail as a (commonly, usually, often, etc.) slacker-angled

Grabbed a table:
28mm rake on 74-75deg head tube angle. Hmmm... 1.1", about what the
builder of my track bike said he built for that bike, with
"about" (or, "at least") 75deg head tube angle.
If you find a real (oval blades, straight brake bolt hole g) road
fork with 28mm rake, let me know, would you?
Although I haven't had any problems with the old "Cinelli" (and maybe
it is a Cinelli) road fork that's in the bike for FG road use, which
is probably a 43-45mm offset, I'd like to have something closer or the
same as the original fork, as that bike handled great on the track and
was not "twitchy", nor did it tighten line in corners unless I wanted
Please. "Responsive". Typical of the track bikes I've ridden (not
many, true enough, but I went through the rental fleet at Alkek),
rides straight just fine, turns quickly when asked. Not "twitchy".
Doesn't tighten line unless you want. Steep head tube angle, short
