Boardman 9.x saddle rail clamp

javidr

Hi

im having issues with the saddle clamp of my Boardman bike. It is sliding backwards, and I think it’s because the washer is a bit bent and doesn’t lock the saddle

its the second time I have the same problem so I would need to find either a replacement for the washer or for the clamp, but it doesn’t seem to be a standard one

Can you advise where could I find a compatible replacement? I know Boardman would sell that part but I would prefer to avoid buying the original Boardman part as it is problematic

thanks

I’m wondering if part of your clamp is missing. I don’t know this post, but often there are two clamp plates, in addition to the one piece post and your bolt.

I can’t imagine how you could bend any washer if it’s in the correct place.

Hi. Yeah I saw that one as well but seems unrelated

there is no part missed, and maybe washer is not the right word… if you see the picture there is a thin plate between the screw and the clamp. I fear I might have tightened the screw too much and it damaged the plate. That’s just my gut feeling

Is the plate you have flat? Usually arch shaped to fit into the clamp slot

Yep it’s flat, the problem is when you tighten the bolt too much it gets arched and doesn’t put enough pressure on the clamp

do you reckon it should be arch shaped?

any idea where can I buy those?

thanks

My guess is that someone missed the proper part out during assembly.

Need to try whoever makes the seatpost, but you may be ok with a generic. No idea where i would buy one - usually just rummage around my bits box, but it would be with an old post.

Take the seat post in to your local bike shop and see if they’ve got an old part that fits.
