I'm really trying to get a reflecter off the front of my bike, but a bunch of other things are broken.

Story you can skip: Went riding yesterday on my Schwinn Traveler and was riding a hilly part of our city, and was cruising down a hill at a good 25-30 mph, giving moderate pressure on my brakes to control my decent.


In the middle of descending, I noticed a big giant grate-like thing sticking up out of the road (construction workers must have left it there). Seriously, it was sticking up about a good 2 inches, probably to slow cars down or something stupid like that. I jammed on the brakes and was in the middle of shouting a ton of expilatives when I hit it really, really hard.

The chain somehow came off, and I thought my front wheel was toast. Not as much damage as I thought, but both the front and rear wheels were out of true.

I figured it would be a good time to learn how to do that (and it'll cost me $40 if I don't) and spun the wheel around a couple of times to see where the problem was. Walked away, and when I came back, the wheel was totally flat. No biggie, just a flat tire. Then I picked up the bike and realized that the stem had come out of alignment. Got a pinion wrench, and started to tighten it when I heard *ping*. The thing it connects to had fallen off. Sat there for almost a half an hour trying to push it up with a screwdriver to no avail, and I couldn't get the stem off because the shifter cables were holding it back (downtube shifting) so I disconnected all the cables and finally got the metal thing out. Went to


So now I got to fix the wheel, tire, shifting (tears) and the stem, all from hitting a stupid bump. Purely astetic, but there is a dumb reflecter on the front which I have wanted to take off for a while now, and now that I can finally access the bolt, I can't get it off. I tried getting it off with a plumber wrench, but its totally stuck, and I don't want to damage my fork. Don't you have to take it off to install a new fork anyway, so it should come off, right? Any ideas? I'll post a picture in a second when I find my camera.

EDIT: Pictures:

big long crescent wrench, oil and hold the fork still if you don't have the thin spanner to fit on the nut under the reflector. You could do this with a 2x4 near the base of the forks.

Note, that crummy reflector serves the function of also being a locknut. When you get it off you will see. Local bike shop should have one of these. You do need one with the little nub.

but don't use the pipe wrench on the nice chrome nut: it will chew it all up!

g' luck!

I'm sure you meant that the reflector bracket serves as a washer rather than a locknut...

this is a situation where some basic MTB skills would have helped. A bit of a bunny-hop would have cleared that buisness with no problems.

Got the nut off. I went to four of my neighbors to find a big enough size. Unfortunately I need to go get a washer, BUT my car won't start. Alternator died. How incredibly lame is that?? Add that to my list of stuff to buy.

Speaking of, I did bunny hop it, but it was about six feet long so I struck it in the center and bounced accross it. Really nasty business.

The 2x4 trick worked excellently, by the way. Thanks for the tip! All I need to do is assemble everything together again, and then...true the wheels somehow.

Another question:

What should I ask for when I go to the bike store? The spacer thing in between the nut and the fork? It says this criptic number thing on the reflecter mount: A-1-72
(72 has a degree mark after it)

a-1 is the part's model number. 72 is the angle of the head tube that the bracket itself was meant for to insure a proper angle for reflector operation.

72 degrees is very common for these, I am looking at an old cateye H-3 right this second that has a 72deg bend.

Basically if you want a reflector later on, be sure to use another 72. If not, just show them the reflector and ask if they have a spacer to use in place or anything. I know on some bikes you could just turn the headset nut down further if you didn't use a reflector.
