Responses from vendors would be most welcome as a handful of you seem to
provide many of the valuable responses on RBT
The bike I'd like to convert to flat bar is a mid-eighties Japanese
("Zebra" branded, from South Austin Bikes) (Chalo troll... testing
testing 123 pffft pftttt 12 is this thing on?) 6-sp road bike. Works
fine as is but not for the intended rider.
Suntour 5000 derailleurs. Shortie stem that would be fine if there's a
"flat" bar to fit.
For this application, twister shifters would be desired, as they
(Gripshift 7sp) have been found to be satisfactory on a Specialized
Expedition "comfort" (ha ha) bike, in combination with the long-style
brake levers that bike came with.
The object is a stable hand position and leverage at the brake lever
for a rider with hand difficulties that make drop-bar riding dodgy--
even with a long stem raised up, and brakes "tuned" for max power (new
red pads and close adjustment). Changing hand postions is difficult,
and the "vertical" hand orientation around a drop-bar brake lever and
handle is not good for braking power and hold-on strength compared to
the thumb wrap-around and horizontal hand position with flat bars (I'm
guessing this also an issue with the OP).
Thumb shifters? Probably not.
I got a short distance with this at the FLBS but there seemed to be a
similar bias against this conversion as seen here. "Bring it in", what
they seemed to be saying "We really don't know how to do this but we
might figure it out". More than I want to spend <g>.
IOW, the case for drop bars is well understood but in this
application, moot.
(stating the obvious) I'd like to keep the wheels and derailleurs,
change the handlebar but stem only if necessary, put a 7sp freewheel
on, use 7sp twisters with long pattern brake levers, and perhaps
different brake calipers, to ensure maximum "easy" brake power.
Feasible? Hardware suggestions, please?
BTW: There were good indications for Ergo (Campy) during a brief try-
out on one of my bikes, ridden in a stationary trainer. Fine and
dandy, but maybe for a different bike in the future, after some road
time on a skinny-tire road bike that's easy and safe to ride, i.e.,
lighter/more fun (!) than that bomber Expedition which was bought, and
has served well, as a trailer/solo bike for the local dirt-surface
hike n' bike trail. --D-y
