    I'm new to the carbon steerer world, and prefer to not fvck up $2,000ish worth of new forks for my bikes if I can help it. Whats the best way to cut the steerers when it comes time? For the 20-25 forks I've installed in the past, I've used a hacksaw or pipe cutter depending on what was available with equal success. I know with the CF a hacksaw will be the only option, but is there anything else I should keep in mind when doing so? I'm assuming slow is the key. Would taping the steerer help in reducing the risk of fraying/taking chunks out of the edge? I've heard a couple horror stories of the edge getting pretty chunked out if you go too fast. I'd like a nice, clean edge if at all possible.

    get the higher tpi blade, a little tape doesnt hurt, and measure thrice, cut once!

    really not that much different but i put some wet papertowel down to catch the carbon dust. cut smoothly.

    No star nut, compression plug, ENVE, FSA, or go to your trek/special ed store they have all kinds of choices.


    Do what I did, if you can, cut an inch higher then your planned length so you can see if your blade is going to tear the ship out of the steerer.

    This, also use a guide to make sure it's not crooked and lots of cutting lube cause no one likes to breath CF dust.

    I use gloves when cutting CF to prevent splinters. Happened once and that was enough.

    <3.....The terrorists can never take away crabcore, remember that.


    First fork install went smooth as buttah. Picked up the right compression plug gizmos from the LBS today, as well as some brand new 32tpi blades. Even broke down and finally bought the Park steerer cut guide, which I always thought was a huge waste of money, but I've never been this paranoid about effing up a fork install. Did a practice cut as suggested by 4xBoy, and was smooth and trouble free. Luckily the real deal was just as good.

    Nope. Still waiting for the 456 carbon frame to show up from On One (have the full build already). The FTM Carbon still has a drivetrain and brakes to be acquired.

    So much carbon...

    you should seal the face where you've cut the carbonz, otherwise water may get in and damage it severely.
    this is no joke, btw...

    ^^^wise words.

    Epoxy diluted in alcohol about 50-50 does the trick.

    How do you like the 456C? The frame is bullet proof except for the paint which is softer than babycrap. I built mine with 650b wheels. :weee:

    Honestly, I've been having more fun on that than I thought I would. It's the first XC/trail hardtail I've ever had, and really only built it up since I had a complete XC build kit left over from my broken Turner Burner. Took 4-5 rides to get used to how to ride a hardtail, but it's getting more and more comfortable, and slowly getting quicker on it. It's pretty light and super stiff and responsive.

    Haven't noticed any issues with the paint, then again I really only ride smoothish XC trails with it. I do have the chainstays protected though.

    You spent $1200 on suspension. Spend the extra $60 on professional labor.

    Right, because a hacksaw is beyond my capabilities. :rolleyes:

    I've seen the work of plenty bike "professionals". I'll pass.

    Exactly my thoughts.

    Many "professionals" are unfortunately somewhat less than adequately skilled.

    Between this and the broken chain thread, your credentials are questionable at best.

    Either way, both forks have been installed and ridden for a couple months with no problems. Apparently I'm not an idiot. Whoddathunkit?

    that's why we drink it here
    The best saw I ever used had a ceramic blade on it. The edge looked like sandpaper. It ground through the carbon instead of biting into it with individual teeth. Polish down the edges with some emory paper and you're left with a very clean surface.

    I like the idea above, sealing with watered-down epoxy.

    Park makes a cutting guide for steerer tubes which is a nice luxury if you do this often. A pair of old, blocky bmx stems is a nice option if you're going at it with low funds.

    i've been at shops as a customer (in the time since i used to be a mechanic) several times where i've had to go back into the shop and show them how to use the tools correctly. pathetic.

    at this point the only service I need to go to a shop for is facing and chasing, and that's only because I don't want to spend a grand on a set of tools that will get used once every 2-3 years.

    Agreed, though I'm wary about even taking it in for that. I just pray some overzealous wrench doesn't leave me with a 30mm wide BB.

    That and I don't have a park tool FAG. Not will I rebuild rear shock dampers.

    also, when I lived in NJ, i had sort of a deal worked out with the local shop. They'd let me use some of the stuff I don't have (truing stand, headset press), and give me like 50% off what they would charge.
