HEAVY RIDER BREAKS THE SEAT
April 6, 2005
Back to questions
I had a custom fit done on my
new Specialized Hardrock Comp XXL (I’m
6’5”, 235 pounds), and part of this custom fit
was pushing the saddle as far back as it could go, making
the seatpost clamp go to the very front part of the saddle’s
rails. After I bent the rails on the saddle that came with
the bike, I put another saddle on, and I had bent the rails
again in a couple of days, and then one of the rails actually
broke as well.
Today the bike shop gave me a new
saddle embossed with the words “Liberator Ti Race.”
The salesman assured me that titanium rails would hold up.
not sure I’m
going to be comfortable with this new saddle, however; I
much prefer “comfort” saddles. I just bought
a new Body Geometry Comfort Plus saddle, which I’m
very used to and love, but I’m
afraid to put it on the bike for fear of bending and/or
breaking the rails.
I know I could adjust the saddle
to position the seatpost clamp in the middle part of the
rails, but then I would lose the geometric adjustments done
as part of my “custom fit” (and this fit has
made me feel better than I ever have on a bike). I could
also get a seatpost with more of a “layback”
to the clamp, but I don’t
believe they make extended-layback seatposts with shocks.
One mechanic suggested getting a
seatpost with a longer clamp on top, but would adding just
a fraction of an inch to this really make a difference?
Any suggestions you have would be appreciated. Thanks.
I like to say that the more hardware
you use to fix a problem, the more problems you end up with
Unfortunately, to address your problem’s
three parameters—setback, strength, and cushion—I’ve
had to create a real Frankenstein monster of seat configurations.
I think it’ll work, but the villagers might riot.
First, to get the seat back far
enough we need a laybacked seat post. A couple suspension
posts—such as the Bracer Offset models from Post
Moderne—do have minor laybacks,
but I presume you need something more dramatic, like a curved
Next, we need a way to grab the
seat’s rails in the right spot so you can use non-titanium
rails without bending ‘em. This we can do with a device
made by M2Racer called the Power
Module—which basically lets you slide a seat back
and forth without moving the seat post clamp.
Last, you need that cush. I suggest
you try a leather Brooks
spring saddle. The combination of leather (conforms
to your sit bones) and springs gives you both comfort and
You could start out using your Body
Geometry seat instead of the Brooks saddle, but you might
miss the suspension. You might not.
