Too Much Seat post??

[jinjrich]

With no tyres on the rims, the frame sits lower relative to the floor, which makes the saddle to top tube gap look even bigger. You also have the saddle slid forwards on an inline post on a frame that is potentially too small, if the saddle was in the right position it wouldn't look so ungainly. Worth a few adjustments I reckon.

Good advice. I'll build it up and have a proper ride. I have so much stuff in the shed i'm trying to decide what to store away, what to build and use, and what to sell on. This is a recent purchase and i really like it, so worth some effort and patience. Cheers!

Phwoar what a whopper! :shock:

I have a very nice banana impersonating seat post from having too much sticking out.

Thats also a worry! The O beam in there at the moment is very slightly bent backward- only perceptible if you put a straight edge on it, or if you have micrometer eyes like me

Pip weighs the same as a bag of sugar. In fact he floats on the bike so he's an exception. Best not compare him in this scenario ;-)

What are you trying to say?

I think how much post is inside frame is more important!

It will be fine if enough inside, its just down to looks then.

As Mark highlights, you will be safer with the bottom of the Seatpost sitting a least 2" inside the main frame's triangle.

On my 1996 Ku, the USE Alien Aluminium 420 is (obviously) 420mm long, so there is 2 1/2" of Seatpost inside the frame's triangle.

There are tremendous leverage forces on the frame at this point. Just think about it - sticking (probably) more than 150lbs on the end of lever.

As Big Al points out, I weigh sod all, but I'm not happy with anything less than a 400mm Seatpost in an 18" Kona frame.

WOW! 242lbs..... that about two of me :shock: .

HM, you have seen my svelte like build (or skinny as it's also known) on the "Today's Ride" thread. Are there any pictures of you on this forum - it's just that I had a different image of you in my head for some reason :? .

Cheers Pip.

I weigh 165 lb and will certainly have less post than you sticking out so i reckon it'll be fine. It was probably (although i don't like to admit it) also down to looks- i think too much post doesn't look good aesthetically- but i stood the bike in the living room last night and i reckon i can live with it!
