Salsa Shaft seatpost setback?(3 posts)

Salsa Shaft seatpost setback?Fred2000
Jun 12, 2002 9:44 AM
I am looking for a long seatpost (~410 mm) with set back.
I know the Thomson Setback has 5/8", Race Face XY ~ 1" but I didn't know and could find the set back on the Salsa. Any info would help.

Thanks, Jon

There is no standard reference point (or line) for measuring "setback". The 5/8" (15-16mm)dimension that Thomson quotes for their setback post is only for comparison with their straight-up model. The Thomson setback post still has less setback than many other brands (like campy, shimano, ITM). You can tell about as much by looking at a decent picture. The limiting point is the front side of the seat-rail clamp. On traditional road posts, like campy's, the front of the clamp is located approximately at the centerline of the post. ITM's post has about 1/4" more setback than a campy post. The cheap Kalloy post also has slightly more setback than others. From catalog pictures, the front of the Salsa clamp appears to be very close to the center of the post, like many others.

A dimensioned drawing like Thomson has on their website would be great to have, but unfortunately, I know of no other company that posts this information, so I rely either on good pictures or a personal inspection at the LBS, if possible.

I e-mailed Salsa with the same question They answered as follows:

"The set back on our posts (measured center of the post to center of the clamp) are 23mm, not quite an inch."

Hope that helps.
