I'd be happy with Torx bits. Well, you'd be happy until the day you realized you you needed to make an adjustment and you'd left your Torx tool on your workbench. Your pocketknife won't work with a Torx screw. Can we compromise? A Torx head with a slot for emergency non-Torx use? Remember, it's just an adjustment screw. Hold on a second Frank. Didn't you just say in a nearby post? More seriously, brakes don't have to be adjusted very often. It's reasonable to require a tool for that operation. So where do you sit on this? :-) I'm in the "almost any tool should do it" camp. Same as the guys who put in the slotted philips screw heads. It occurs to me, I've never carried a Torx driver in my tool pouches. I'd be ticked off if _anything_ on my bike absolutely required one. Doesn't affect you, but some relatively inexpensive folding tools now include the disc brake Torx driver. We sell them, but I can't imagine a use for it while on a ride. With motorcycles; I've been known to lay the machine on its side to avoid losing the oil while I take covers off to work on the engine. The one I particularly remember, the nut that holds the drive gear on the end of the crankshaft came off. With no drive, it was either push it home or fix it. Obviously no spanner that big in the toolkit, but I managed to tighten the nut using a reversible screwdriver as a punch - it was good enough to get home where the right tools were. |

I like lawyers lips. LL are cool like airbags. My tool pouch includes an assortment of socket set type driver bits which include popular Torx sizes - but they tend to be a bit wobbly for setting adjustment screws. |

Sure... take a break. By coincidence, a friend just called asking for help removing some deck screws. His vision is marginal, so he didn't see or clean the dirt out of the screw head. Paper clip and paint brush cleared the hole and out came the screw. And he didn't reach for the impact driver!? I think I'm in the wrong place here :-( Actually, he did. He was once a professional tower climber and installer. He's now about 72 years old, and had to quit because of poor health and overpriced insurance. Before he retired, he was using an impact drill and impact driver to compensate for his lack of strength. I build him a set of "torque amplifier" handles for socket wrenches. Before attacking the deck screws, he phoned me asking if I had some square drive bits for the impact drill. A stripped screw head would have been guaranteed. http://shop.marshfasteners.com/images/SQUAREDRIVEMOM.JPG After a few minutes interrogation, I determined that the problem was that his last remaining square drive bit would not fit in the screw hole. He thought the problem was the driver bit, not the accumulated crud in the hole. So, I suggested he clean out the hole with a paper clip and brush. Then pound the driver bit into the hole. Once seated, use a non-powered tool to break it loose. After that, spin it out with the impact drill. I haven't heard back if it worked, but will surely find out today. Incidentally, he's looking for a cheap tricycle to get some exercise. He has balance problems and can't handle a conventional bicycle. I just started looking, but am rather discouraged at the high cost of tricycle conversion kits and ready to ride machines. If anyone has any leads to a *CHEAP* kit or machine, I'm interested. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

More seriously, brakes don't have to be adjusted very often. It's reasonable to require a tool for that operation. Brake blocks wear rapidly while the slotted bit of the contact face remains. Recently I've noticed that new brake blocks are too short to wear any further than that! I've had to pinch the short spacers of old blocks to jack the brakes up a bit. If I don't do that, the cable stirrup hits the opposite calliper by the time the blocks are only half worn. |

As yet I haven't seen any multi-tools with Torx bits, they would probably start to appear on the market if cycle manufacturers started using them. I went to chain reaction, tools, multi tools. The first two listed are these : http://www.chainreactioncycles.com/t...l/rp-prod47016 http://www.chainreactioncycles.com/c...19/rp-prod7455 and both have torx. I've not looked any further. It's a few years since I first saw them. |

A Torx head with a slot for emergency non-Torx use? Remember, it's just an adjustment screw. Sigh. I have 3 different multiplex-tools that spend most of their days in my bicycle junk bag. Plenty of problems with multi-tools. For example, some operations require two tools and I don't like disassembling the multi-tool. The tool arms are not long enough to apply much torque. The folded tool also grinds holes in my pockets. What I carry is a 1/4" drive swivel head wrench, adapters, and a plastic bag full of driver bits and sockets. Also a few open end wrenches, small crescent wrench, chain tool, tire levers, and double ended screwdriver. My tool collection is bigger and heavier than a multi-tool, but far more usable. Adding a few Torx driver bits to the collection would be easy. Incidentally, my handiest tool is a double ended pocket screwdriver: http://photo.oempromo.com/Prod_149/Pocket-Screwdrivers---Double-Ended_73844756.jpg The blade end is useful for prying, scraping, removing road crud, turning a #2 Philips screw, starting Torx screws, stirring chemicals, mixing drinks, and simulating a tooth pick. I also have it magnetized to help start screws. Yikes. I didn't realize that there were so many different styles of bicycle specific multi-tools: https://www.google.com/search?tbm=isch&q=bicycle+multi+tool That kinda suggests that it's a solution looking for a problem to solve.

I'm sure I could design some CF aerodynamic knobs that will suffice. Or, maybe just reduce the weight with some drillium or maybe make it hollow with a 3D printer. More seriously, brakes don't have to be adjusted very often. It's reasonable to require a tool for that operation. I beg to differ (as usual). Requiring a tool might be reasonable, but more likely, it's just cheaper not to add an adjustment knob. For some odd reason, I seem to have chronic problems with brake adjustments. It's probably caused by my juggling wheels between bicycles to see how they ride[1]. To get the brake pads to be parallel to the rim, I need to do some major brake adjusting. If I change the rear wheel, the rear derailleur shifter also needs adjustment. I don't do this too often, but when I do, it's nice to have a convenient knob for adjustments. Also, I can use a knob while moving, but not a hand tool.
