two finds

first, according to this shop owner, Sun has made their CR-18 rim in 650B. coincidentally, i emailed Sun yesterday to ask when and if they'd do exactly that. this means 650B is doable for about $70 less in rims, although tires would still be pretty steep; Harris has NiftySwiftys for $40 apiece, as opposed to about $40 total for a set of Panaracer Tourguards.

i stumbled across this browsing the KOG message boards for info on trail...there's a link to a very interesting .pdf of a Vintage Bicycling Quarterly article comparing the Kogswell P/R with three different forks.
