Since no one has answered, I will give it an educated guess. I love pre-dawn detective work. I have neither the plans nor the bike yet, but taking measurements off the profile photo (assuming a 700mm wheel) I get somewhere between 53" and 55" for the wheelbase. I'd call it 54, but to be honest that seems way too high to me, based on the wheelbase of the Bacchetta bikes (46"-48") and the fact that the same measuring technique yields 192mm for the crank. Admittedly the crank is closer to the camera in the shot so it will appear somewhat larger. I suspect that crank is probably 175mm, which would yield a wheelbase closer to 49." Camera, Parallax error(?), or maybe Canadian 700mm wheels are smaller than the ones we have in the US :jester:

Wasn't it the Virginia Slims cigarette that was a silly millimeter longer in the TV ads?

Actually, it was the Chesterfield 101s which spawned that ad.

To paraphrase the actress at the end of the commercial - I'd like the HighRoller even if it wasn't 1 millimeter longer. Time for some coffee!!

Funny how our minds remember such nonsense. That phrase "a silly millimeter longer" is still floating through my brain more than 3 decades later, and I don't even smoke and never will. For some reason I orginally thought this morning it was a Virginia Slims commercial (another one that was so wrong on so many levels).

This 24" is at 45-1/2" on the axles. I used a smaller boom for a shorter person. Could be a few inches longer, plus or minus, with a longer boom

I will measure mine when I feel brave enough to head outdoors to shovel out the garage!

48" exactly axle to axle on mine.

Great - so my eyeballing the profile with a ruler was only off by 2%, using the crank length, and not tire size. Thats not too bad, but it still makes me wonder about those wheels again. I know you said they were 700mm, but my ruler on the picture says 631mm from tire edge to tire edge (the part that hits the road). I have a Canadian Miele road bike with "700 cc" wheels. It is running 700x23 tires and measures just at 692 mm from tire edge to tire edge. I have a set of 26" wheels running 26x1.25 tires that measures right at 622mm. Just looking at your pics I think you are running fatter tires, but something isn't right somewhere. In addition, I don't see many Schrader valves on 700cc wheels, but I know they make them. Very puzzling - like a song I can't get out of my head lol. You sure those are not 26" wheels in the picture of your HighRoller Brad?

Yes, the ride photos were taken with 26 inch rims... good call. I built it with my 700cc rims, but was too scared to use them around here due to rough roads.

Pheww! Thanks Brad. Now I can sleep at night knowing I don't need a new ruler.

700c tyres arent 700mm
theres different sizes of rims and tyres in the 700 series
700a is a balloon tyre. Only really used on dutch roadster bikes. They have a larger rolling diameter than the 700c tyre.
maybes thats what they use on the 29er bikes you can get these days?
