am i able to do this?
 

i want to make my bike lighter...i'm thinking about grinding some of the seat post down to shave a little bit of weight off...can i do this?

Yes, you can cut the post.

ok...i think i can go to my friends house because hes got a bench grinder

How much do you think you will lose?

Cut post and bars.

Switch to magnizum pedals over aluminum(in some cases)

Change tires...odd as that sounds a tire like a Tioga Comp III is about 1/3 less weight than a Primo Wall for example.


Get a lighter stem

Cut axels flush with bolts.


Fill your tires with helium...
Pray you don't try the last one.

Don;t grind your post. Cut it with a hack saw.

True dat. Why didn't anyone else say something?

we dont care enough

ok

Yeah, cut it just enough so the clamp has room to grab it, and slam the seat.

Good answer.

leave about 2 1/2 - 3 inches minimum

And don't listen to Matrix

best. advice. ever.

why?

i have read alot of his posts and they are correct answers. people need to relax in here dayam

Yeah I don't really see any problems with advice he has given at all really. he may anoy some of you but he's a memeber of the forum just trying to give some advice. For the most part he isn't really very unreasonable about things.

i used a pipe cutter to cut mine, if you got one, they do a nice job making the end even. how would you cut the axle to make the threads even?

Put a nut on the axel where you want to cut it off, and cut it with a hack saw against the nut.

or a dremmel

Oh, ok thanks.

How much axle can be left on each side, at the least? Just right up to the axle nut?

That is the worst way to cut an axle; it's almost never even, takes forever, and it won't be chamfered.

Mark the length you want to cut it a piece of tape, cut it with a Dremel (or similar tool), and then file the corners down to an angle.

Thats how I, and most of the others I ride with do it, and it has turned out fine for all of us...I don't see how it could not come out even... there is a steal nut there to cut against as a guide.

Yes up to the nut.

use a nut as a guide over tape. but yea use a power tool over a hacksaw. that takes forever.


try a hacksaw on 41thermal that would be fun.:rolleyes:

How much lighter will it make the bike? How much wieght will that take off for all 4 axles?

You only have two axles.

not alot but it shaves some. plus it looks clean and pretty. you may loose 4-7oz on a really long axel and thats for all 4

7.946384 lbs exactly.
