Reduce weight: cut off seat-post ?(7 posts)

Reduce weight: cut off seat-post ?Derrick VL

My Ritchey Pro seat post is 35 cm long. I only need 20 (10 cm outside, 10 cm inside frame).
Can I, to reduce the weight, simply cut it off 15 cm (so it still is 10 cm in the frame as it should)?
Not only CAN you.Spoke Wrench

but now that you've started to worry about that extra weight, you just about have to. Otherwise you'll feel like those useless grams are holding back your bike on every climb.

Here's the REAL danger that you need to consider. Once you get started on that kind of weight shaving, it's just a tiny step to buying expensive titanium bolt kits.

cut it off only 12 cm - maybe you will need that extra 3 cm someday (new saddle, pedals, shoes, sale of bike...)
You must! There's 15 grams at stake!Kerry Irons

That's as much as 1/2 of a swallow of water from your bottle. You absolutely cannot continue to ride with this kind of extra weight on board.

In the meantime I have cut the seat post 14 cm.
Extra saving of 60 g.

May sound ridiculous, but when I look at a seat post of 225-60=165 g which equals mine (165 g means carbon), I have saved a lot of money in 10 minutes...

I've historically run mtn seatposts on my road bikes for the sheer fact that I'll switch seatposts back and forth between mtn bikes, road bikes (both regular and compact), and any other bikes that happen to live in my garage at the time.

Yes, there's a slight weight penalty, but the flexibility of not having to go to the LBS and buy a new seapost every time is worth it to me.

My Dean Ti post has been on 4-5 different bikes in the years that I've owned it. Had I cut it when it was on my road bikes, it wouldn't be on the Dean mtn bike I just bought...

never thought of that.niteschaos

That'll be a good way to save a few bucks when I get another rig.
