May 18, 2002 8:51 AM | | 2002 Specialized Enduro: I'm looking to upgrade the seatpost to a Thomson Elite. Do I need the 12 degree tilt option? |

| clamp angle depends on seat tube angle of your bike | devildog
May 18, 2002 4:42 PM | | From the Thomson manual:
The 0 degree clamp is for seat tubes with angles greater than 70 degrees.
The 12 degree clamp is for seat tubes with angles of 70 degrees or less.
The 12 degree clamp will also work for seat tubes with angles greater than
70 degrees.
I just installed a straight post with a 0 degree clamp on a bike with a 73.5
degree seat tube angle. To get the seat level the front bolt was screwed in
substantially more than the rear bolt. According to the Thomson manual this
is not a problem because the design has positive metal stops which prevent the
bolts from causing damage from not being screwed in enough. It was close getting
the seat level though with the 0 degree clamp. The 0 degree clamp still has 17 degrees
of tilt adjustment. I haven't had any problems after 500 miles.
Knowing what I know now I would get the straight post with the 12 degree offset clamp to give
me more evenness on my bolt adjustments front and rear. |
