Rail type question. Vanox vs ?

Jumpy

I just got the new saddle in with the cutout and swapped it for the current.
Apparently the new seat has Vanox rails, whereas the old one does not, I have no idea what the old one has but its slightly thinner and rounder, whereas the Vanox is more squarish (if that is even a word).

Now it is just a little too big for the grips, so they dont close on it the same way as the old one. It looks steady and tight, but I thought I would just pop the question off here. Are all road bike rails to a close enough standard?

Never heard of Vanox rails but...

I would want to be VERY*sure that my saddle is connected securely to the rest of my bike - have you seen the state of our roads? One bad pothole and it might not be "vanox vs ?", it might be "crotch vs top-tube" instead. Or "face vs wall".

I'd either get a new saddle or a new seatpost rather than bodge it a bit and hope for the best. Another boardsie posted pics of himself showing the results of a saddle/bike separation at high speed during the TOI, it was harrowing stuff.

*yes that's all caps italics and bold. I mean it.

The thing is I cant find a seatpost specifically for Vanox type. I took it for a spin tonight and its perfect. But it just looks a little off at the clamp.

The only thing the seatpost clamp says is max 16Nm. Now unless they are really tiny, I assume it means 16mm. Its just the slightly squarish shape thats throwing me.

16 Nm = 16 Newton Metres. It's a measure of the amount of torque that should be used (with a torque wrench!) to tighten the clamp.

Vanox is simply the brand name to the alloy Selle Italia has for the alloy on some of its saddle rails.

Some saddles and seatposts don't match well together. If you're unhappy with the clamp, swap out the seatpost.

16 Nm is "quite tight" by the way- by way of comparison you would probably do your bars/stem/seatpost up to around 5 Nm (that is what mine are specced at anyway.)

To be honest you will probably notice a loose saddle slipping before anything catastrophic like saddle loss happens, that has been my experience anyway. Depends on the specific clamp design I guess.

The exact answer I was looking for. Thanks man.
