Seatpost Markers

Hi guys,

I am looking for way to mark my seatpost position on my bike for shipping and fine-tunning my riding position purposes. I have used Sharpie markers, but they always rub off after a while. I know Nashbar sells an o-ring type rubber for $1.95 that can work well, but I do not want to buy it for $1.95 and then pay $9 to ship it.That would not be a cost-effective way to solving the problem.

There must be a way, apart from Sharpies or duct and masking tapes to mark seatposts.

Any suggestions is welcome.

Thanks

personally i just use a small flathead screwdriver and scrape a mark right above the seat collar. It works pretty well and it doesn't rub off. I probably wouldn't use this method on a carbon seat-post though.

But . . . using Sharpies or a small piece of electrical (or packaging or strapping) tape works.

If the concern is that a Sharpie mark wears away, any downside in re-marking it 3-4 times/year?

Scraping a mark on with a flat head screwdriver can eventually compromise the structural integrity of an aluminum seatpost.

dont kid yourself too much, a little surface scratch probably cutting in .001" maybe .002 is not going to cause any harm.

The distance from my lower pedal in line with my seat tube to the top of my saddle is exactly 36". Once you know that there's no need to mark your seatpost and you can adjust any bike's saddle height in just a few seconds.

I just rub a pencil line around it. Lasts for as long as I need (adjusting time).

How about a simple 1 foot piece of cloth ruler (such as dressmakers and tailors use), and just measure the distance... Weighs next to nothing and folds incredibly small.

Move the rear reflector holder ring to the bottom exposed section of the seatpost?

Measuring the height isn't precise enough for me, because I feel a lot of difference between, say, 36" and 36.05". Electrical tape works decently, but a fixed pipe collar (available at your neighbourly hardware store) or a reflector braket are great.

If you like the idea of the rubber o-ring you could always head on down to the local plumbing supply store and buy one for under a dollar.

Thankx all,

I just went to my local Ace hardware store this morning and bought some rubber o-rings for 33cents each. I took the seatpost with me and made sure I fitted the tightest o-ring I could fit. It works great. I bought half a dozen of them b/cos I think the ultraviolet rays from the Sun might not be very good for the rubber in terms of holding together.

Anyway, things are fine for now.

Once again, thank you all.

The quality control of the guy that I buy my socks from isn't that consistant.
