Sliding forward on saddle - need advice

[lph]

As long as you tighten your saddle snugly after adjusting it you can't do anything unsafe. Yes, the curvy thing has ridges (probably) on it so that you can adjust the tilt of your saddle. Loosen the bolt that holds your saddle to your seatpost until you can wiggle the saddle around a little, settle it horisontally and tighten the bolt again. Testride and redo if necessary

As you're loosening the bolt check if it goes through a nut on the other side, you might have to hold onto this nut to get it tightened again.

If you find yourself pushing yourself back on the saddle anyway, to get further back "behind the pedals", you might want to try moving the saddle back a little as well. Loosen the bolt, slide saddle back a bit along the rails, re-tighten.

If you have trouble, post a picture and we can help!

tilt the front of the saddle up a little bit. that might help.

Don't know if this will help but here it is.

I had the same issue when I tried a seatpost that looked great but had more setback than what I needed. Now that I switched back to a seatpost with less setback I do not have the issue.

Yes, tilt the saddle so it seems flat. If you can't fine tune the tilt due to little ridges in the adjuster thingy on the post you can always use a small piece of aluminum can cut to fit on top of the ridges....

I slid forward on while I was riding on the terrible stock saddle. I moved forward because the back was too wide for my sit bones and all my weight was being supported on my soft tissue unless I slid up until my sit bones supported the rest of my weight

If you've never had a professional bike fit, I would do that. It will fix your saddle issues without guess work, and may fix a lot of other things you may not be aware of. If not now, think about getting one in the future from a reputable bike fit professional.

... for the advice. I've adjusted it so that it's pointing just fractionally downwards and will try that out at the weekend. Just a couple of those little grooves makes a big difference in the angle!
