Is anybody well versed or familiar with the crowns used on these two bikes? Particularly regarding the differences between them, and their relative tire clearances?
The recent Reader, #44, included a description of Riv's various, current fork crowns (RC-02 through the new, Appaloosa-style RC-06) but it doesn't really answer my question. I have a first-run QB, the crown of which looks like the one at the following link (and also matches my Rambouillet). But it isn't even shown in the Reader article. Perhaps it's a RC-01? Or is it the RC-02, which is listed as the Roadeo crown and therefore the narrowest possible option? : original QB crown <http://flickrhivemind.net/blackmagic.cgi?id=2874011510&url=http%3A%2F%2Fflickrhivemind.net%2FTags%2Fcyclocrossbike%252Cquickbeam%2FInteresting%3Fsearch_type%3DTags%3Btextinput%3Dcyclocrossbike%252Cquickbeam%3Bphoto_type%3D250%3Bmethod%3DGET%3Bnoform%3Dt%3Bsort%3DInterestingness%23pic2874011510&user=&flickrurl=http://www.flickr.com/photos/25451876@N00/2874011510> Meanwhile, later QBs and, presumably S.O.s had crowns that looked like the one at the following link. It's hard to tell from photos whether this is an RC03 or an RC04, though I'm guessing the former. Both have the little scroll detail with three dots above: Later Quickbeam crown <http://farm4.static.flickr.com/3656/3577001997_71ca22526a_m.jpg> My main question is whether or not the later QB/SO crowns had significantly more clearance than the earlier ones. My reason for asking is because the Rosco #5 is said to be built around a surplus Quickbeam / Simple One fork, and I'm trying to figure out what that means in terms of real world tire clearance. It is the later of the two above styles, and the bike's listed as having a max tire clearance of 40mm (though I suspect that's a typo and it really meant to say 44 or 45). But is this the conservative dimension Riv is required to cite as a manufacturer, or does it jive with what QB/SO owners have been able to do? Though I'm at the upper end of the fit spectrum, #5 is the first Rosco that's looked like it will fit me, but I'm trying to figure out if it's something I'd use. My QB is the most comfortable bike I own, but I rarely ride it precisely because it is limited to such narrow tires. If #5 doesn't improve on that significantly, then it's likely just too much overlap and redundancy. #5 also shares the same, steepish 72 seat tube / 72.5 headtube angles with the QB (which I suppose is why they describe it as "roadish"), has horizontal dropouts, and is bright green. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
