Going over the limit (seatpost)

lovely Campag post off egay for the princely sum of 4 quid.

trouble is, I need it to be that high, so only about 55mm in the tube.

seems ok, but will I die?

anyone ever snapped a seatpost? I've only busted them on MTB and BMX when crash landing, not when sitting on them

£4?! sshhhhhuddup man you are devaluing my assets!
Seriously, you could screw up your seat tube... i would consider it a risk at 87kg- are you a featherweight?

The seatpost needs to go past the point where the bottom of the top tube meets the seat tube.

Beyond this point butting kicks in (on butted tubes) and unless you have a plain gauge seat tube - pushing the seatpost any further in does not offer any more support.

13 stone = 82.553 811 34 kilogram

oh.

it was only cheap cos of the funny size (26.6) I'm guessing.

it hasn't been cut down, but they are pretty short anyway innit.

I suppose it's partly cos the frame is a 57 and I'm really a 58..but fuck it.

a 6'2" mate rode the same seatpost with that same amount over the limit no problem. he was superlight tho. i would be nervous about doing that myself.

Nah listen to tynan he's well smart....

this has always been my belief too,
well it goes way past that, about as far down as the point of the lug on the seat tube. and yes it's butted.

although, I think if it might bend or break the post if it was inserted only that much?

Remember all limits marked on any item are a compromise between the engineers estimate and the lawyers comfort level. Plus what tyan said as well.

:D

I will have another go, don't want to disappoint anyone.

"The seatpost needs to go past the point where the bottom of the top tube meets the seat tube . . . as any metallurgist will tell you."

thanks chaps.
I'd expect the rails of the brooks to go before the seatpost or seat tube, judging by the movement when I grab hold of it and put some beast into it

Dont do it! I fecked up my lovely Kona that way

i broke a frame setting the seatpost like that :(

what happened then?

RPM

Rusty nuts!

Eeeew.

s'all that rain.

it's only a chro-mo bolt

My crank bolts are even worse.

But my Royce stainless ones arrived this morning ;-)

Bling bling!

If it doesn't go past 'Tynan's Line', it won't be the seatpost that gets damaged, it'll be the seat-tube/top-tube cluster.

yeah, seen a few examples of people snapping off the top of the seat tube.

get a new post a.s.a.p

it IS the new post.

gutter

What do you expect for £4? ;-)
Sell it again with BIN of £20 and a proper listing - it keeps the market buoyant...

and obviously where the frame scoops down it's only about 45mm in the tube, it shows where in the copper grease.

bah.

someone's going to get a lovely seatpost included with the frame when I eventually sell it.

bollocks.

back to using a real POS stick n' clamp arrangement
