I'm a Perl coder living in Bethlehem, PA and working Philadelphia. I'm a philosopher and theologan by training, but I was shocked to learn upon my graduation that these skills don't have many associated careers. Now I write code.

building by bike repair toolbox

[ #28188 ]

Among my Christmas presents were a few bike tools. The packages said they were from Santa, but I think my mom actually wrote that -- the handwriting looked a lot like hers. Those tools were all Park tools: an FR-5 freewheel tool, a BBT-2 bottom bracket tool, and a CWP-6 crank puller. I was pretty excited to finally have a couple of tools, and a few days later I decided to see how much I remembered from class.

It went pretty well. I hadn't completely forgotten anything, although I originally had the wrong tip in my crank puller and stripped a single loop of threading from my left-side crank. Oops. Apart from that, everything was fine until I tried to remove the bottom bracket cup. The recommended torque for a Shimano bottom bracket cup is roughly 600 to 700 inch-pounds. My ratchet was about six inches long, and bottom brackets don't have a very deep keying, so producing 100+ pounds of force on the end of my ratchet was going to be too difficult and dangerous. I needed a longer lever.

I didn't try using my freewheel tool, because I didn't have a chain whip.

The next (or maybe the same) day, I ordered a chain whip (SR-1) and a really nice pedal wrench (PW-4). I don't have those yet, so I still haven't taken my rear cassette off.

Today, though, my dad took me over to Sears and I picked up some simple tools that I needed. I got a ten inch adjustable wrench, a deep 15mm socket (for turning the crank puller's plunger), and a longer ratchet. At first, I was despairing my inability to find a long 3/8" ratchet with a solid (not a flex) head. I finally asked the Sears guy, who dug through a drawer and finally looked up and realize that there was on hanging on a hook right next to the one I'd taken. I felt dumb.

I later realized that I'd grabbed a 12-point, and not 6-point, socket. I'm not really concerned about that, though. I'm not going to be applying huge amounts of force to my crank puller.

I also picked up another socket. The freering tool has a hexagonal profile, so I figured that I could use a socket. None of mine were large enough for it, so I checked out the sockets at Sears. It as much to large for the 24mm socket and much to small for the 27mm. I tried the 1" socket, knowing it wouldn't be a perfect fit, and it was just a hair too large. I figured it must be a 25mm hex, then, because all bike tools are metric. My dad and I hunted and hunted for a 25mm socket, most of which were found only in enclosed sets. Finally, he found an exposed 25mm box wrench, and lo! The freering tool didn't fit. It must actually be a one-inch hex. What the!?

Later research showed that they expect me to buy and use a "freewheel remover wrench, which is basically a box wrench with a tightening nut. That seems completely ridiculous to me. The only reason I can see is that perhaps the standard 1" socket is too deep (the whole remover fits in the socket), but I don't think that will be an issue in practice. I'm going to give it a try and find out. Failing that, I'll call the local bike co-op and ask whether I'm missing something.

I'd like to get a nice chain checker (the kind that can tell you how badly your chain has stretched) and a new set of Allen keys -- the Park set is nice -- but other than that, I'm all set. I can get by with what I have for a good while, now.

  • Are you going to be mountain-biking in the mud and thus rebuilding your bike every year? Or are you going to be the neighborhood repair shop? Or are you going to be constantly upgrading components? I consider myself to be half-way decent repairing my own bike but I don't have half those tools. I say get the tools as you need them.

    What I'd recommend is a good set of hex keys. I've been drooling over the long handled ones. Like http://www.parktool.com/products/detail.asp?cat=7&item=PH-1 [parktool.com]

    I saw how muc
    • I want to be able to repair my own bike and my friends' bikes, and replace any component I want, when I want to replace it. (I might not replace my own hubs, though. Ugh.)

      I do get a lot of crap in my bike, and being able to take apart the gearsets to clean them is a real plus.

      The PH-1 set is nice, and I'd like to get one, too. I used them at the local bike co-op when I was doing things there. Also, buying tools when I need them is annoying, because if I don't have a specific tool, but then need it, I ha
