Why doesn't Thomson make a Carbon Fiber
Seatpost?
Q
- What colors are Thomson seatposts available in?
A
- Black or Silver
(Certain sizes available in black only)
Q
- Are you going to add other colors in the near future?
A
- No, we are not planning to add new colors.
Q
- Can I buy a seatpost direct from Thomson?
A
- L. H. Thomson Co. does not sell any bike products directly to
consumers or Dealers. We sell directly to Distributors and OEM's
only. Your bike store can order all of our products from our distributors.
Q
- Where can I order a seatpost?
A
- Contact your local bike shop. If the bike shop is out of stock,
they can order any of our products from one of our distributors.
Q
- What is the cost of a Thomson seatpost?
A
- See our seatpost pricelist.
Q
- Are you going to introduce new sizes for the seatpost?
A
- Yes, as the market demands.
Q
- How do I measure the length of my seatpost (from what point to what
point)?
A
- We measure the Thomson seatpost from the bottom of the post to the
centerline of the seat rails.
Q
- How far does the set back seatpost set back?
A
- 5/8 inch or 16mm of set back.
Q
- Can a setback seatpost be turned around and used as a "set
forward" seatpost?
A
- Yes, the setback seatpost can be used as a set forward seatpost. No
modifications are necessary. The forward direction or set forward
works well for converting road bikes into triathlon bikes.
Q
- Why are the front and back walls of the Thomson seatpost thicker
than the sides?
A
- When a rider sits on his or her seat, the weight of the rider tries
to bend the seatpost backwards. This produces more stress in the
front and back of the seatpost than on the sides, so we put more
material where the stress is the highest. Removing the materials from
the sides where it is not needed saves 30 to 40 grams of weight depending
on length.

Q
- I lost my bolts, and I can't find any at the hardware store. Are
they special? Where can I get some?
A
- Our bolts have been specially designed to work with the Thomson
seatpost.
First of all, there is a spherical radius under the head of the bolt,
which allows the force to be evenly distributed across the bolt head,
as the bolt swivels during seat adjustment. A standard bolt does not
have this feature, and would be more likely to break. Our bolts are
made of a high strength steel alloy, and go through and extra
manufacturing process that increases their fatigue lives.
Finally, Thomson seatpost bolts are plated to prevent rust and
corrosion. As you can see, bolts from the hardware store would be
very poor replacements for Thomson bolts, and would cause failure and
void the warranty. Contact your local bike shop for replacement
bolts. The bike store may order bolts from our distributors. Only
Thomson bolts may be used on Thomson seatposts.

Q
- Can I use titanium bolts on the Thomson seatpost?
A
- We do not recommend the use of Titanium bolts. There are no
titanium bolts available with the proper spherical radius under the
head of the bolt. Also, most grades of titanium are not as strong as
the high strength steel alloy that we use in our bolts.
Q
- My Thomson Seatpost hits my rear suspension. Can I cut the end of
the seatpost off? How should I cut it?
A
- Warning: Once a seatpost has been cut off, the Max Line is No
Longer Valid! This can lead to dangerous situations where the
seatpost is not inserted into the frame far enough. Damage to the
bicycle, seatpost, and/or injury to the rider could result.
Cut
the post using a hacksaw. We do not recommend using a pipe cutter.
Pipe cutters mar the finish, and are difficult to use on the Thomson
seatpost.
Be sure to round the corner where the seatpost has been cut using a
file or a deburring tool. Mark a new max line on your seatpost that
is as far away from the end of your post as the old max line used to
be.
If the seatpost has been modified, the warranty is at our discretion.
Q
- Can I use a seat with carbon rails with the Thomson Post?
A
- Yes, you can. The only thing that needs to be done differently is
that the seatpost must be completely disassembled and reassembled
with the seat in the rail grooves. This is so to avoid scoring the
carbon fiber rails.
