Bob Jackson Q
 

does anybody know if there's any toe-overlap on the Vigorelli Track frames?
size - 22.5 inches /57cm with a size 12/13shoe?
worth a shot- thanks.

i have no toe drag on my custom jackson. i use clipless and ride size 46 sidis. my geometry is 58st-56tt and 74.5d on both tubes.

it's close... but it never hits--even though i expect it to.

Not sure, but I think the Vigorelli is built to be a grass track racer, and has a bit more lax geometry than a traditional track bike. I don't have a Bob J. myself, but I'd guess that if there's overlap, it's probably not a lot.

picture? i'm sure its out there already, but help a lazy man out.

it's a little different at the moment though.

No overlap on mine. It does have a more relaxed geometry. Here, in Noah's Arc bars mode.

Wow I love you.

This and a green Bob Jackson I saw awhile ago are now two of my top favorite bikes I have seen.

thank you all,
your a brave man choosing that colour for that bike- i like it! (the chain too)

Hi tony. You've seen my bob jackson (the massive one) and I doubt you'll be surprised to hear there's no overlap. But all the off the peg vigorelli frames are pretty relaxed and have clearance for 28s so I doubt you'll have any overlap on that frame.

hey naz. did you just base the colors off the website? seems to be quite a few options and possible combos. also did you do the assembly / prep or have a shop (marcus?) take care of it.

I got the colours from the website. I knew exactly what I wanted since I was basically resurrecting my first fixie, a conversion. That old frame had gold lug outlines but I wanted silver for this one. White decals were easy to pick.

I have all the tools and knowledge for putting a fixie together save for headset tools but I negated that by buying a campy Record headset from Bob J (it's cheaper there too) and had them install it for me before shipping it over so all I had to do the day it got here was put it together. Since I had to wait, I slowly accumulated parts from ebay and the like and built the wheels for them (my second wheelbuild). It was actually going to sport a different wheelset but the Campy Omega Stradas were on eBay, NOS, for a steal.

I keep tweaking that bike though since I love it so. It's gone back to drops (the flat bars were for fun) and it now sports a Brooks Swift. I continue into retro-grouch/comfort land. I save the agressiveness for the Italian and Japanese steeds.

nice.
not in the market for another nice ride but looks like a good option.
i am sort of looking for foul weather beater

You could always make the BK your beater. :)

nice idea. don't know if my wallet will like that.
would be easier to replace than the nishiki that was plan A for wet/winter weather. just need to see if those clip on fenders will fit on the BK front tire has a pretty tight clearance. i was hoping for something i could move over my full commuter fenders over to.

This is my 1997 Bob Jackson Messina. It does have a tab of toe overlap.

I am certainly no expert. So hopefully someone can help me out here.

From what I see of the two Bob Jacksons in this thread the clearance up front is pretty lax. In my mind I am comparing this to my 1983 Kenevans which has about an 1/4th of an inch between the tire and down tube.

This is something I see on modern track bikes pretty often. So my question is this; why do older frames have such ridiculous clearance up front between the wheel and down tube while newer models don’t? at least don’t look like they do.

I know that for the Vigorelli and the model I have, it's a grass track racer and thus is built to take a 700x28c tire easily with clearance to spare. My frame was built to be a 53 but has a higher bottom bracket than my other track frames, again for clearance. I wanted it this way too since it feels a bit larger and more road-like -- I was looking for something comfortable to ride day in and day out and over long distances as well.

The Vigorelli, if you want it, can come with fender mounts free of charge so fender clearance can be achieved.

As for Visitor's, his is fully custom, so he'd be better to answer that. Though he picked a 74.5 angle so that would explain it.

in my case, i just requested that there be no overlap for my body's geometry. they basically got it exactly right.

somewhere, don had a pretty good/concise explanation of clearance with respect to one of his walker team issue frames.

Does anyone here own a 20.5"(52cm) off-the-peg BJ vigorelli frame and get any overlap? Yeah, I know it's something one can get used to, but just wanted to know before shelling out so much for an off-the-peg frame.

Where can I find geometry for a Bob Jackson?

email them.
i ordered custom because the off the peg geometry was not what i was looking for...but that last silver BJ that was up here looked like it had nice geometry.

Thanks, but that doesn't have Audax or Vigorelli, which is what is sold off the peg.

only had overlap with 172.5 cranks. i have 165's now and medium christophe clips.
head tube angle, rake, and top tube length are the same as VisitorDesign's
74.5, 30, 56cm
