Removing a dent

I have an aluminum Yeti frame with a quarter-sized dent in the top tube. Is there any way to get it out? I know Al doesn't bend as well as steel, but.. ?

Old suspension fork

I'm looking at getting a 98 Rocky Mountain and it has an old Marzocchi Bomber X-Fly (Z2 I think). Does anyone know how well these things hold up and if I might need to replace the fork? I have no...

This may constitute a new thread entirely, but from what I've heard the stiffness of newer low-spoke rims largely makes up for the low spoke count, but no FE analyses to back that up here, sorry. My...

Ah, then tell us, what is the One True Model of forces in a loaded wheel? I fail to see how that diagram is wrong, given that it's on a computer program with inputs for spoke tensions and load...

I had the exact same problem with my RSX front derailer brifter. It sounds like you are doing the same thing I was, which was to very carefully downshift by applying just the right pressure in just...

What's the point of talking about spokes as springs just to say that the hub hangs from the rim? Spokes are not springs, and while they are susceptible to lateral deflection, they do behave as a...

I went looking around the interweb and found this to support me:

It has some finite element analyses near the bottom, which I found helpful, as well as...

I had thought that while the bottom spokes support the load, the increase in tension in the other spokes can be attributed only to the maintenance of equilibrium and not to the load, thus the bottom...

Mechanics of the tensioned load-bearing wheel

I remember reading in Jobst Brandt's "The Bicycle Wheel" that the tensioned (bicycle) wheel supports a load by standing on the bottom spoke, which loses part of its tension force in proportion to the...

Okay, thanks a lot. I had no idea cross-chaining was so strongly frowned upon. This is my first bike with STI, the last one had friction shifters so chain rub was never a problem.

In my experience, if you're doing it right, it will sound like something is going horribly wrong with your hub. Put the non-drive side in a vice, put the lockring tool in the cassette and the chain...

I know that QBP carries some lower-end 8 speed stuff for Shimano, but I'm not sure about Campy. If you did find a new 8-speed hub out of QBP, it wouldn't be up to date - ie higher spoke count, more...

Bent chainring?

I bought a used crankset from a guy who had crashed his bike and then decided to buy a new one. I've been noticing that I'm getting chain rub on the front derailer on both the low and the high end of...

Thank you for all the help. My main concern is whether I'll be able to replace the screw: that is, not whether I can find an appropriately sized replacement, but whether I will be able to get it back...

(mostly) Stripped hex screw

I have a recessed hex screw to adjust tension on my pedals, which I bought used. Unfortunately, though I would like to raise the tension, the screw on the left pedal is adjusted all the way to the...
