Re: [RBW] Question about stand over and head tube
Hi Joe, It is definitely a 700c wheel but the bottom bracket may be low compared since it looks somewhat like Steve P has on his. The chain stay is not level with BB and is actually slanted downward to meet the bottom bracket.

Re: [RBW] Question about stand over and head tube
If i understand your question correctly: 1) bottom bracket height matters a lot. For a given (& workable) standover height, the saddle can come down closer to the top tube with a corresponding drop in bottom bracket height, which then brings saddle and handlebar heights closer to equal - before even looking for other tricks like extended head tubes or tall stems. 2) the riders of most of the bikes you're looking at probably dont sweat the standover clearance (they're not "crotch-worriers" as riv terms it). It is likely much more minimal than you're used to. 3) most bikes fit better for people of average proportions, or those with long limbs (inseam) and short torso. Someone with shorter legs, of an otherwise identical height on an otherwise identically sized bike, might actually prefer the top tube to slope down from the headtube connection, and have more seatpost. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Question about stand over and head tube
Lee, if you're getting a lot of seatpost and stem showing, but little standover clearance, you're probably on a frame with a high bottom bracket and 700C wheels. For an extreme example of this you can search stuff about the Pashley Guv'nor. That bike is based on an ancient path racer design with a bottom bracket almost level with the rear dropouts, and when properly sized has no or even negative standover clearance. I hope our answers have helped a little bit. There's quite a few variables involved, which is why folks like Grant work so hard to sort them out. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Question about stand over and head tube
I am asking how frame builders are designing bicycle that look the way they do, without sloping top tubes. My mind says it is not possible without a high top tube, yet bicycle frame builders are designing frames that look like the Herse you have in this email. Part of the reason I am thinking like this is that I have a old bicycle with a pretty flat top tube or looks like there is no slope in it at all, yet the bicycle requires a dirt drop to get the handlebar high enough. The top tube is high so there isn't room while standing over it. Its weird in my mind but I do have alot of seat post and stem to get me up there. More than what is shown in the pictures you have Patrick.

[RBW] Question about stand over and head tube
My 51cm Appaloosa has 6 degrees of rise to the headtube, then the headtube juts up an inch over that, plus the steerer adds another inch. So I get a couple inches of standover in front of the saddle, but don't need a tall stem because so much height has been added to the frame up front. The front height can be duplicated for me with a mostly level toptube, but would require a 53 or 54cm seattube, robbing standover clearance. In the olden days this was a common setup..folks didn't concern themselves much with standover, they just rode big frames with slammed seatposts and stems.

[RBW] Question about stand over and head tube
This is a question towards people who are involved in frame design but anyone can respond. I have been thinking about this but it has been more academic than of practical use. I have looked at bicycles on Flickr of MAP, Rene Herse, Grand Bois, Rivendell, Mariposa and others but I have always thought how can these frames have such headtube lengths with stand over of the top tube that fits the rider. It would seem that most bicycle should have a slight, slant towards the head tube from the seat tube to give stand over clearance while feet on the ground but my mind keeps saying that the stem should be much longer that what is shown in these picture. You can only go so high on the top tube due to stand over and to get any adjustment for handlebar, it has to be mostly stem if you are somewhat of a average size person but the stem on these bicycle are not long at all. In fact, they look sensibly and lend towards the aesthetics of the bicycle. Can anyone explain that? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
