Never-answered question about rims
M13II by Sun-Ringle... polished silver finish, brushed sidewalls... do these qualify as unanodized? Or must the rims tarnish in order to pass the test? At: http://www.sun-ringle.com/prods/oemrims.html I see only an anodized version and it doesn't use spoke sockets, only eyelets. I don't know what the idea is behind that but all good rims that weren't deep aero cross sections used to have spoke sockets that distributed loads to both inner and outer beds of the rim. Rims without sockets cracked. Better yet, what are rims such as the Sun Rhyno Lite? They appear to be painted, but I usually refer to it as anodizing. If it is truly anodizing, then the brake pads should wear out long before the anodizing wears away, no? Anodizing does not wear away on the inside of the rim or on the bed where the spoke loads bear. If you post a URL with your comments, looking at the rim would be easier. I'm sorry... I forgot to be clearer. My Rhyno Lite has unfinished braking surfaces. I took some pictures... The rim and tire... crappy joint. http://plaza.ufl.edu/phillee/crap/um1.jpg Zoomed-out view of the next pic http://plaza.ufl.edu/phillee/crap/um2.jpg Original-sized cropped view of the rim http://plaza.ufl.edu/phillee/crap/um3.jpg Zoomed-out view of another section of rim http://plaza.ufl.edu/phillee/crap/um4.jpg Original crop http://plaza.ufl.edu/phillee/crap/um5.jpg The last picture demonstrates my use of mud to break in the pads and rim surface early on in the rim's life. It worked quite well. Something to note: I had excellent braking performance when the anodizing was still there... as the miles rack up, glaze and possibly invisible stuff has polluted the surfaces... I would rather ride with muddy rims than clean off and/or sand pads and rim surfaces. Another question: does everyone see this happen on their unfinished rims? http://plaza.ufl.edu/phillee/crap/rim1.jpg It appears to be that the rim is being pulled away at the locations of the drive-side nipples (picture taken from the nondriveside). The other side of the wheel demonstrates much less of this effect. -- Phil, Squid-in-Training |

A slight deformation of the sidewall appears to be caused in manufacturing by spoke bores, but has no effect on performance. Jobst Brandt |

I think this indicates that the spoke tension is causing the rim to
deform slightly at the spoke locations. I don't necessarily view that as a problem, though; it certainly does not seem to be causing any difficulties. I've noticed this type of wear pattern a number of times, and it does not seem to be associable with any pattern of failure. I think it's due to spoke tension, too, because the wavy pattern is apparent to a much higher degree on my non-drive-side than on the drive side. Thanks for the testing and hard data. -- Phil, Squid-in-Training |

Oddly enough, in looking through the rest of the used wheels, I ran across a Ritchey front rim that had the wavy pattern reversed; the wide spots ae at the spokes, rather than between them. Most of the rims showed no wavy pattern at all. This still looks like it's more of a curiosity than anything else, though; it doesn't seem to have much of an effect on the usefulness of the rim. -- Typoes are a feature, not a bug.
