Saddle Shifting Fore/Aft
Hi all,
really dumb question here.
Today I've replaced my bike's saddle with something slightly racier. After fine tuning the position though, I'm finding that however tight I clamp the saddle to the seat post, over the course of a ride the saddle shifts backwards by around a cm...
I have absolutely no idea why this is happening, since it didn't happen on my older saddle, and I've tightened the seat post as tight as possible....
It's a Selle SMP Stratus saddle, on the *default* seatpost on a Specialized Secteur (here: http://www.evanscycles.com/products/...-bike-ec019549). I think it's a standard Specialized one.
I've had the original Specialized and a Brooks on the bike without problem, so I'm a little confused as to why it's happening with this one. Only thing I can think of is that because of the way that the Selle SMP is angled, means that I have to tilt the nose up a little further which causes the rails to be angled upwards towards the front of the bike. Maybe my weight is then causing the saddle to move backwards...
Any ideas?

Not all saddle rails are the same diameter. you may have bought a saddle with smaller diameter rails that don't quite fit the clamp.
i would have thought it would be obvious though.--
