There are different possible head tube lengths. Most are 4" or 4.5". S&M makes the Tall Boy frame with a 5.15" head tube. http://solidbikes.bigcartel.com/product/integrated-headtube-quick-taperhttps://www.sandmbikes.com/product/hardgoods/frames/crumlish-sig-tall-boy-frame/ I know this post is old, but it's still a topic that someone could ask and it still comes up at the top of ... more »

STOUT http://stoutbikes.blogspot.com/ can make one for you custom at a good price.

I think it's from around 2005-2007. I had one.

Yes, you can buy complete wheels, and you can usually buy a single front or single rear as well.

I got a buddy in Pasadena. Kinda far from you I guess. You should stop by the Anthills (also far, but worth visiting).

Agree with above, but just want to mention that 22" tubes are pretty easily available through web stores: https://www.amazon.com/Kenda-Inner-Tubes-Schrader-SHIPPING/dp/B00ZICCWRO/ref=sr_1_3?ie=UTF8&qid=1499266601&sr=8-3&keywords=22+X+1.75+bicycle+tube I like both 22", 24", and 26" mtb. basically 22" replaced 20"s for me.

I don't see how it could have any effect on strength. If anything, more offset seems slightly less strong (like it would put more stress on the dropouts).

I don't quite understand why kijiji is a thing in Canada. To me, craiglist is much clearer, less cluttered. But anyway. . . .. This would be a very cool bike. MacNeil is a Canadian company (Vancouver area). They sell higher end frames and forks, handlebars, ... more »

Anything sold by empirebmx.com, albes.com, or danscomp.com will be good. They don't sell junk.

What make/model is it? Got a photo?

A front hub is 100mm spacing, right? And a rear hub is 110mm. So do you have 5mm of washers inside both dropouts, or did you just squeeze the frame together that much?
