WHich do you prefer? You can switzerland this one if you have some good reason to, like a studious explanation.

Dumb question. I have yet to see a Torx head on my bicycle. Thats like asking which thread pitch you prefer.

You don't run discs?

Anyways as I said, I think the ideas behind torx are based on bullcrap. With a light hand and some skill you will likely never strip a good allen bolt and/or overtighten.

I have had more than enough problems with torx to hate them.

I think for the applications which I've seen Torx heads being applied on a bicycle which is primarily disc brake rotors, an allen will do. A Torx head does have advantages over an allen head but none of those seem to be applicable in this case.

Torx are more applicable to the automotive industry. I guess I just figured that the bicycle industry wouldn't kid themselves into thinking such high strength fasteners are needed. Then again, I have seen them holding bathroom stalls together, but I think that is more of a vandalism deterrant.

Thats my point exactly...

they have torx bolts all over school. I guess they figure the students dont know what the hell it is. They had a group of people that would bring in wrenches and screw drivers, removing the nuts and bolts that held together desks so you would sit down and the desk falls apart. they started putting torx bolts on there, it stopped for a little. But it wasnt long until those desks started falling apart again

Torx sucks. And I hate Jeep for using them on their vehicles.

That is where they make sense though. The forces on a bicycle are mere FRACTIONS of those in a Jeep, and the bolts must be very precisely torqued down. On a bicycle, it is important for things to be tight. Thats really about it. A few spots you want to make sure everything is precise, like in a fork or the linkages in full suspension, but on cranks, pedals, handlebars, etc, just as long as it's tight. I am going to make it my mission in life to give Shimano and the industry a reality check.

I can see why they're used but man it sucked when I misplaced my T55 wrench at the end of a trail run and had to drive all the way home with my swaybars disconnected.

lol

sounds like good times at your school.

Lol. I feel your pain. I have an 89 Cherokee that my parents let me fix up. Its fun until you run into a stripped/rusted torx bolt.

I think that Allen screws are better. The tools used to drive them dont bend as easily. Cheaper torx drivers suck; all the tabs bend, causing them to slip.

* TORX requires no insertion pressure for driving and no cam out forces are generated.
* TORX has axial power transmission areas, Tools don't slip. Reduces possibility of distorted screws.
* TORX has 6 large torque transmission surface areas that allow for higher sustained torque forces.
I've never had a torx bolt strip out on me and I can't imagine what kind of ham fist could strip one. On the flip side I've had allen heads round out on me and that's SO much fun to work through.
Phantom this was covered recently in a thread that YOU responded to. Why bring it back up?

Problem is, you can only have so much power transmission area until the driver is too weak and bends. I have seen a number of stripped torx screws, which all had to be cut with a dremel and taken out with a good ol' screwdriver.

Funny, I guess when you use decent tools.....

whoever said it you were right. the origin of the torx is in the automotive industry. i think it was ford that did it a while back. they made all their bolts and screws on the entire vehicle torx so you would have to take it in to the dealership to get it fixed. this was when you could fix a vehicle without having to have a computer and electonics to fix it with(no computer run stuff)a marketing ploy that worked for a while before a company bought the rights for it and mas produced it.

i like torx because like ryian said really hard to strip. (never stripped one myself)

"Light Hand"????

The purpose of Torx is being able to torque something enough to the point where it won't come loose without either damaging the tool or the screw head.

Torx just plain does NOT strip.

It does when you use the wrong tool or size on it, but that's about it

Rotor and Crank Bolts. If they could make "Torx Nut Spoke Nipples" I'd be all for that as well.

Not all allen bolts strip. But when I look at my well used allen tools, I can clearly see that something is getting smushed.

Read this

I have no problem with Torx, I believe there are good applications for Torx head bolts, and having them on my rotors is a good application in my book. If you refuse to believe the engineering behind Torx simply because you don't like the user interface, chances are you're using the wrong tools or hamfisting stuff. IMHO the difference of the user interface for Torx and Allen heads is so minimal, but I digress.

Not to sound like a bastard, but this has been cover at length before in the above link. If you really don't like Torx, just got find Allen hardware that will do the job for you. Just please don't wrench on my bikes

It's the thread I mentioned earlier. I guess some people can't leave the MTB section for some reason or other

Ahh right you did. Credit given where credit is due.

Maybe it's time to bring back the animated search image you have.....

Honestly, the only reason I would do Torx is to make sure no one stole my rig (even then I would put rubber cement in the screw heads). Allen heads are the most obviously needed and are easly "theft deterrant".

The sad thing is he responded to that thread. It's not like he didn't know it existed
