Re: Magnify Glass vs Jewelry Microscope Magnifier Loupe

the "magnifier" doesn't magnify at all, it shows only 1:1 reality scaled images. :/ The only way to zoom in is to physically put the lens closer to the object, which blurs it out, making it useless as an actual magnifier. Amberwolf, Does the Re-Focus button operate? Can you "zoom in" physically, as...

Re: spoke nipple diameter

Minde, FWIW, you can get dedicated washers to fit various spoke nipples. Check the bike shops locally, or maybe the Internet. The size of the spoke holes in the rim probably won't matter much, using the washers that will exactly fit the nipples. Automotive paste wax will minimize corrosion between t...

There are a number of threads dealing with the torque arm vs dropouts issue.

I have a friend who will only use steel front forks on a front-wheel drive system. He reports breaking some aluminum forks in-flight, with predictable results, especially when using the stronger motors. Just a thought . . .

Re: Lots of punctures - replace with solid or puncture resistant

To my post back then, I would only add that you may wish to cut away the tire beads from the inside tire. It may not be necessary, though.
