Seatpost woes

UndercoverElephant

Well now, I'm currently going to have to stop riding my lovely BeOne, as the seat-post seems to have bent, erm... under the power of my awesome/weight of my arse.

I had to stop three times last night to stop it poking upwards. Looking at it, where it used to go upwards, then across (sorta like a tick), it kinda goes upwards then bends round in a circle making it impossible to keep a seat still on it. The seat-post will have to go back to CRC for replacement, leaving be a bit bikeless in the meantime.

Please tell me this is rare, and the meanwhile wasn't correct about road bikes only being for featherweights. :oops:

Quite surprising. What BeOne is it? I'm 13.5st and ride a Storm 1.0 and it's been fine. Would have thought something else would go first - wheels, bearings, chainstay welds...

Any piccies?

Sorry to get you all over-excited, but I'll stick to the seat-post pics, if you don't mind. For reference, it's a Mistral, and I weigh about 13st 10 lbs.

Here she is:



I've tried to straighten the saddle again, using a longer handled allen key for more purchase, I'm sure that it won't make too much difference. Three times last night was too much, and I was rather sore when I got home . As I recall, the back of the seatpost used to point horizontally, rather than the downwards it is now.

buy a better seatpost, maybe a thomson, or one of the exotic ones from ebay that are pretty reasonable.

That looks a bit weird. Not seen that design before. + 1 for Thomson. I have one on my commuter.

Surely the idea of that post is similar to this one -

I suspect that the problem is that the clamp isn't gripping the angle-adjust region of the post.
I fear that the fact it's now rounded off a bit means it never will.

If you think its likely that you will get a new post anyway, and it its possible to tighten the clamp to the post independently of crushing the living daylights out of the saddle rails, application of sufficient violence may be worth a try.

If that fails, order something from Wiggle, take the post out and apply further violence.

(Note 13 1/2 st is nowhere near enought to have bu*[violated]*ered that seat post. It probably worked loose, or wasn't quite tight enough to begin with).

Suspect the clamp bolt simply wasn't tightened enough to start with. I've found posts of that design usually work pretty well.

Hmm, I'm pretty sure it was tight, it didn't move at all for the first few hundred miles. Something must have happened, as I just can't tighten it at all now. Who knows though; I've never had problems with ANY seat-post before.

Bought a FSA carbon seat-post from Planet-X for the princely sum of £20. I'll get CRC to replace the Ritchey one, and flog one or the other back on eBay. Bit of a pain, that's all.

Same seatpost as my Cube

cant see anything wrong with the post. maybe just not quite enough tightening force.
