cutting a carbon flat bar

[W@nna-BE]

hey hubbers

 

i am keen to buy a used carbon flat bar from a fellow hubber, but its not the right size

can i cut it to size as the LBS did with my original steel bars?

[Jewbacca]

yes... Measure it up and use a carbon bladed (normal will work) hack-saw and a cutting guide. Sand the edges to remove burrrrrs and Robert is your Fathers' brother...

ok cool thanks, and i thought Bob was your Uncle lol

Another tip is to tape the ends you are cutting with masking tape.

This helps prevent the carbon from splitting at the end where you cut.

Get a pipe cutter that plumbers use. Mask up area as mentioned. Gives a much cleaner cut.

 

Retracting this as its a bad idea I've been told.

Don't use a pipe cutter, use a carbon saw blade.

Welcome back stranger...

 

Personally I am a believer in using thin abrasive cut off disks.... but that assumes you are into power tool usage - does give a nice smooth finish on the end.

 

I don't for a second believe that using a plumbers pipe cutter designed for copper pipe will work well - definitely going to crush the inner layers of the carbon - not good.

Masking tape and cut with a blade. The only way to get a clean cut without getting carbon everywhere

Best thing to do is leave them for a month.. dont cut them..cause then you wont want to cut them

[W@nna-BE]

lol thanks 2Nutz, but i currently have a 600 so used to that size

[LazyTrailRider]

What width is it currently?

 

If you're used to 600 (crazy narrow), definitely don't cut it. Give it a few weeks getting used to a wider bar, then come back and thank us for nudging you in the right direction.

 

Seriously, don't cut it.

I'm with the first try it uncut guys, I always rode with 580 wide bars but tried a wider bar on my 29r and loved it! Have now changed all my bikes to wider bars, give it a try.

lol@power tools....,

 

 

Air power actually.. although a dremel is also a good tool for small work.

 

I am also of the opinion the op should leave the width on the bars and see after a week or 2 how it goes - despite having grown up on 580/600mm bars, I have stretched them to 680 - and that works for me - wider gives me some shoulder and elbow pains.
