Quoted message said:Any suggestions for a seatpost that'll put me forward on
my road bike, closer to the bottom bracket?
I'd prefer a regular one with enough arch in the tilt to
allow me to adjust the saddle accordingly if I were to
turn it backwards. Otherwise I'm open to a post with a
bend in it.
Thomson makes a good post but if you accept a no-offset one
you can get a Nashbar (reg 25$) or the Giant one Nashbar
has on sale for 12.95. These don't allow you to move very
far forward.
Race-Face has one which looks like it would work but I
emailed them and they (promptly and nicely) said no (or they
didn't want to worry about liability).
I have a Control Tech which does handle the angular
adjustment turned either way and seems plenty stiff (it has
an extra longitudinal web extruded up the length of it).
Picked it up scratched but cheap.
Remember that 1cm fore-aft change is about 1 degree seatpost
angle approx: arcsine( 1cm / distance from hip joint to BB
axis) so to get from 73 to 78 deg you want 5cm (about 2in).
The back edge of the Control Tech clamp is at the center of
the post axis when flipped, about 1 in forward of the
unflipped position so its only good for about 2.5 deg of max
effective shift forward relative to unflipped (which seems
to match my Titec and Avenir clamp positions). I used this
post with the seat shifted max forward on the rails. It rode
harsh that way but that was with a crummy seat.
Now I'm using a Profile Fast Forward which seems to be
setup about
3/4 in forward of the Control Tech setup (seat and post
are still intact on the bench). I'm playing with my
position but I have plenty (too much?) rail to move
further forward.
Maybe you're interested: I'm also using a M2racer
PowerModule with the Profile Fast Forward. its about 120g
$42 allows on-the-go seatpost adjustment with a quick
release. You slide along the seat rails (about 4 cm = 4 deg
angle on most seats). This thing positions its clamp forward
about .5 to .7 inch of your post clamp. You also move
forward some more because you slide the post down in the
frame some to accomodate the PowerModule's height.
I might try the PowerModule with the Control Tech.
After some rides I find I like forward position. Now I want
my old Nashbar frame (damned 25.0 post dia.) fwd further so
I switched from integrated to a straight alum. post with a
cheap-cheap stamped steel (kids bike) clamp. These flip
around nicely and put the rear edge of the clamp at center
post. Its a good trick for odd seatpost diameters and its a
cheap experiment. Truth in posting: I learned this trick
somewhere on Sheldon Brown's site.
Good luck with it, Ed
