Saddle tilt!

[Pat "5mph"]

Ah, I thought he'd put the offending saddle clamp as his avatar pic

I see, it completely passed me by
You might well be correct with your diagnosis, then!

After taking saddle off to take photos & replacing it the problem hasn't reoccurred on a subsequent ride (tho' the rider complained the saddle had gone down).

If it perseists buy a cheap seatpost and saddle with proper saddle rails

If the photo in your avatar is correct then the clamp was too high up the seatpost, it should go right down to the shoulder on the post to be able to clamp, then you set the height by raising the post in the frame, not by raising the clamp.

Which would suggest that the saddle clamp was not seating on the shoulder of the seat post in the first place.

As an aside, why is it impossible to buy a decent clamp of this type any more? I have bikes from the 30s with perfectly functioning saddle clamps yet I've bought a few new ones from ebay, LBS and Halfords and they never seem to last more than a few years before they start to slip.

Tilting saddle

The saddle before it was removed from bike.

At last I can post piccies. This is the view of the bracket on the post (yes, I know the nut needs replacing). As far as I can see it was securely fastened, but I suspect the serrated(?) portions had somehow not locked together properly. Hopefully it won't tilt again. I know on the bike I'm riding, my son's old Tesco special MTB, I moved the saddle back because I was finding I was sitting further back. There appears to be room to slide the saddle backwards if needed.

I must confess, being much out of date, I thought the seat posts were standard, an unwary purchase taught me otherwise.

Hi,

This happens if the saddle is simply adjusted and tightened, the serations don't lock.
A good bump and it moves and is no longer tight and starts to tilt.
It is important to wiggle the saddle as you tighten it to lock.
It looks better with the rails below the bolt IMO.

rgds, sreten.
