|   Has anyone tried drilling holes into a seatpost? Worth it? | Greg1759
Oct 18, 2003 9:29 AM | | My new 22.64 lbs hardtail will come with a Ritchey Pro seatpost.
I was wondering whether I could drill holes in it to save some
weight. I weigh 135 lbs and I would only use the bike for XC racing
and marathons. How bad would it be if the seatpost broke, anyway?
Are there any parts of a bike you can drill holes in without
sacrificing too much stability? Bar ends maybe?
Thx in advance!

| you should buy a lighter one | Didier Carpentier
Oct 18, 2003 10:47 AM | | hello,
you should invest in a light seatpost.
plenty on the market at various prices.
drilling? man, beside taking serious chances you will look so stupid at your racetrack.
I believe that finishing with a bike that handle the whole race would beat a bike that break all the time. a racing bike shouldn't be too light, yet 21 pounds is easy and trouble free target for a racing HT machine.

| I know. And I WILL - promise. Just thought this could be cheaper | Greg1759
Oct 18, 2003 11:43 AM | | You're right, of course, a "swiss cheese" seat post would be a big
laugh at the next race. Reliability IS my first priority - that's
why I'm asking you SLR-dilling guys here.

| Can't see that happen. | Greg1759
Oct 18, 2003 11:34 AM | | I very rarely ride with my stomach on the saddle.And then only
on pretty smooth terrain. Shouldn't I be able to lift my butt quickly when it breaks? I know this sounds ridiculous. How about some first-
hand experience?

Oct 18, 2003 2:19 PM | | That if it breaks it will happen at the moment that you load it the most. Like hitting a bump during descent.
Most likely you will lose balance and fall. You legs will got loaded abruptly and it will be hard to unclip.
You will go head over heels with you bike, with a broken off seat post, strapped to you. It will make a second asshole in you.
One bright side - at this moment - nobody will laugh at you anymore.

| Drilling holes on the part inside the seattube is fine... | DeeEight
Oct 20, 2003 12:15 AM | | though its a pretty time consuming way to save weight. |

| That was my 1st thought but... | shiggy©®
Oct 18, 2003 7:50 PM | | ... I knew a guy 15 years ago that rode a bike with almost
i everything
drilled out - stem, brakes, seatpost, crank arms, saddle, rims, chainrings, brake levers - and used a hollow pin chain. He always seemed to be recovering from a crash injury caused by a broken part. |
| Yes, way back when it was considered cool | DavidG
Oct 19, 2003 12:47 AM | | I remember seeing lots of photos of drilled-out road bike parts back from the 60s and 70s. In addition to saving weight from the old steel components, if done properly it was also very aesthetic. But I don't think many people went so far as to drill out parts that could compromise safety, ie seatposts and stems.

| Cut it! | CulBaire
Oct 19, 2003 2:50 AM | | Mmmm I dont know about the seat post snaping, normaly somthing like will bend rather than snap...Although the thought of two assholes isn't a nice one; and you wouldnt save that much weight by drilling anyways.
Why not cut the post, measure from where you normally have your post hight, the measure to the min insertion point (normally 100mm) i.e leave 100+ mm on your the bottem of your post (for in the frame)...cut off the excess lenght ;-) Just remember to "taper" or file the burs' off the end of the post so it doesn't damage your frame :-)
I normally leave +20mm for fine tuning seat hight, and cutting my post saved me maybe 40/50gr not alot considering my bike is a pig, but now my post will fit in my other frame aswell :-D

| You could drill holes in your tires to save weight too. nm | beeristasty

| Syncros drilled holes in their Titanium seatposts... | clary.
Oct 19, 2003 7:59 PM | | two of them...left and right holes right at the bottom of the post. |
| That was an anti-theft feature... | DeeEight
Oct 20, 2003 12:14 AM | | and my Ti post shafts have it also. |
| So that means you CAN drill holes in a seatpost... | drilling Bill
Oct 20, 2003 5:43 AM | | if you do it in the right place and if you don't overdo it.
I think drilling holes in the part that is inside the frame
could even be safer than cutting it too short.

| How exactly would that help as an anti-theft feature? nm | DavidG

| Anti-theft feature: remove and put u lock through hole | extralite
Oct 20, 2003 6:42 AM | | If you remove the seatpost, you can put a u lock through the hole when locking your bike up. |
