Hacksaw with a fine tooth blade will work.Chuck731 said:How do I cut the carbon steer tube to the right length cleanly? Can I use a hacksaw? Or would I need some special tool?
Thanks for the replies
1. Use a cutting guide to insure a square end. Park makes a lovely one (Threadless Saw Guide - #SG-6), or, you can do it on the cheap and just use a hose clamp.Chuck731 said:How do I cut the carbon steer tube to the right length cleanly? Can I use a hacksaw? Or would I need some special tool?

I'm just curious. Since one of the world's largest manufacturer of carbon forks - Easton, and the world's foremost manufacturer of bicycle specific tools - Park, both specifically say to use a 32tpi fine tooth hacksaw blade to cut a carbon steerer tube, why would you not follow their directions. What is it you know that they don't? Park advises to keep the blade wet so it does not clog.mitosis said:Use a guide (borrow from the bike shop where you bought the forks) and a hacksaw with a sharp coarse blade (24 tooth - It doesn't make the cut any less tidy and it doesn't clog).

Also, a 24tpi blade would be a medium. 18tpi is coarse.
With all due respect, your recommendations come off as only your opinion and it goes against documentation that the original manufacturer and tool makers' have provided. To suggest that "if you are any good you can cut without a guide" is just plain bad advice. For a headset to work properly you need to do everything you can to make sure the bearings get equal loading all the way around. This is why it's important to check head tube faces for parellelism and reface if necessary.
Cutting a tube with no guide almost guarantees that you will not get good, even loading on your bearings. While your technique may work, it certainly is not a good way to do the job and it goes against all published methods. If you have some source of validation for what you say, please share it with us all.

Still, if you have a miter box or a saw guide, I'd definitely use it!

alienator said:Ask any manufacturer or composites expert, and they will tell you NOT to use a tubing cutter. They don't cut fiber cleanly. It's not what they're designed for. They crush and tear tubing and do nasty things to the resin. In short, they don't do kind things for the CF matrix.
Such advise is uniform across manufacturers.
I wasn't sure it would be a good idea, i'll get the hacksaw out now!Originally Posted by frenchyge .
