A hacksaw is a better method for cutting steerer tubes or seatposts than a pipe cutter. Use a guide if you can, but if you can't.. honestly, it won't matter too much since it's not fitting flush with anything. An old stem works pretty well for a guide.

Lots of discussions in the tech forum on this. A hacksaw is, ideally, a better tool.

I use a pipe cutter and use a dremel to grind the sharp edges smooth. Park makes a tool to help keep a straight cut when using a hacksaw. and then you could use a file to smooth down the sharp edges. You could go either route. Both will work well.

hacksaw is the only way in my opinion because it doesn't stress the pipe and doesn't flair the top. i have see one steerer tube crack do to a pipe cutter being used

Put a stem on clamp it up with an old spacer as a sacrificial guide to cut against and use a hacksaw, will be straight and you won't knacker more than a dollar's worth of components - easy as you like.

well, if you really screw it up, the stem cap might not pre-load the headset bearings properly.


two old stems works even better. but Park does sell a guide which works well too.

as long as the steerer is below the top of the stem / spacers, it doesn't matter how ragged the cut is. i just cut mine freehand then chamfer w/ a file. works fine (as long as i havent had too many beers beforehand).

A hack saw is the proper way to cut a steerer, ALL steerers, including carbon, a proper guide is the way to go, but if one is not readily available, I would suggest the stem, and one spacer method. Works well, may cost you the spacer if anything.

Actually I find six beers or more makes for a better job.:busted:

Two words: Sawsall. :) Jonas and I pioneered this method years ago at Interbike when we were building up proto Sovereigns on the tradeshow floor and were short on tools. It was so gratifying to rip through a pain-in-the-ass job like that in seconds, I'll never go back to a hacksaw!!

That would work quite well!!!

Measure twice cut once! Cutting to short is an expensive, frustrating mistake. If you aren't already set on bar height, leave some room to try some different spacer/stem combos, you can always cut it down again later.

If you are ever cutting bars, using two ODI lock clamps works great for a guide. nice straight cut for bars (where it does matter to have a straight cut)

if you use a pipe cutter wont it make a lip on it, and cause the star nutto come loose? i only use a pipe cutter on seat posts.. cause im always afraid of it

Holy crap, this therad is still going?










































A Pipe cutter has a way of causing Minute stress fractures in the metal of a steerer. Even seatposts I will use a hacksaw....Mainly because it takes a fraction of the time.

I havnt seent he failures myself, But when chatting up one of the Marz techs, he told me they wouldnt warranty a steerer failure if it was cut with a pipe cutter, soooo aparantly there is something too that.
