Why no alu post, light post from Tune, FRM, Thompson, Extralite,...
I have an aluminum frame and a saddle with no padding, so I was hoping to get a post that would shed some weight while being more comfortable.
The bold post is narrowed in the middle of the post so some of the flexing takes place there instead of at the clamp. Good design in my opinion!
I don't know the "Bold" seatpost very good, but fro the pictures i'd say, this most certainly won't work. Roadie magazine "Tour" had a test in their recent issue regarding comfort. They let three different riders (leisure rider, ambitioned hobby rider, Class A amateur) testride on identical material (ordiary oversized AL frame) and changed: Seatposts, tires, pressure, handlebars and forks.
Result: if you want to make a noticeable difference in comfort, play with your tyre pressure, that makes the biggest difference.
If its still too uncomfy, choose wider tires (The A Amateur loved the 28mm Conti). Then came fork and handlebar, effect of seatpost: unnoticeable.
To give "Bold" credit, none of the seatposts used was as extreme in design as the "Bold", but still the flex of the post will be measured in tenths of a milimeter - with tyres, wheels, saddle, handlebar, fork we are talking several mm. The testbikes used had no slope - shorter seatpost. But i personally don't think that would've made much difference.
Seatposts tested: straight Al post, Al post with mounting point 5mm behind, and a Moots Ti post with 20mm.
