[minichamp31]

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?

[wethepeople]

Yes, you can cut the post.

[minichamp31]

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

[Punx]

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.

[MadMan2k]

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

[FitRider 921]

best. advice. ever.

[Qbert]

And don't listen to Matrix

why?

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

[FuzzyRyder]

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.

[BMX1992]

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?

[FuzzyRyder]

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

[premiumbmx2005]

or a dremmel

[BMX1992]

Oh, ok thanks.

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

[CMcMahon]

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.

[FuzzyRyder]

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.

[FuzzyRyder]

Yes up to the nut.

[Qbert]

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:

[BMX1992]

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

[FitRider 921]

You only have two axles.

[Qbert]

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

[premiumbmx2005]
