In thinking about a durable city bombing, leave locked up and not worry...

An MTB frame (hard tail, SS drop outs), painted with spray in bed liner.

Fixed hub, MTB rims, slick tires. Bullhorns.

Just wondering if I could find one in a geomtry that would be enough to get it into a similary seating situation as a road conversion.

Why not? You should be able to stand the proposed bike up along side your road fixed conversion of choice for reference and then make the appropriate choices as to stem length, ect. The only difference is, you probably have to play around with different cog/chainwheel combos to achieve the same riding feel of the road bike. There are gear charts online that will tell you what ratios to use for similar gear inches on either bike. Then there is the 26" as opposed to 700cc wheel size but that is probably not an issue other than appearance. This bike could be used off road with a change of tires which would be another arguing point to the Keeper of the Funds,(wife), which is always a consideration. I say go for it. Nothing is sacred when it comes to fixed gear. Just different ways of doing the same thing.

Who cares if it's "stupid" I just did a crappy Mongoose with Horzontial dropout as a SS. Urban assalt. I din't want to use my livingroom bike (trainer) in the crap or the nice road bike. I just have to get rid of the straight bars.

I guess you could flip some drops up. Now thats "Stupid"!

Would a sups fork affect handling very much? Hmm.. I wonder if I could find one of those light but bomb proof al frames.

Back to the junk bike shop.. and off to find someone to build wheels.

the truck bed liner is an awesome (all be it strange) idea. i've thought about using that stuff on lots of stuff. is there a brand out there that you can apply yourself?

while i was working in london i saw a messenger's bastard hybrid roadbike with sus-forks and drops. looked cool though.

Lots of comapnies make roll-on bed liners that you apply like paint. I bet you could get someone to spray one on, but it would take some convincing. Stuff is HEAVY though. just, for the love of GOD and all that is holy, plug up any and all holes that you will be using, like BB tube, don't spray/paint inside the dropouts etc. A little preparation goes a long way in this case.

Why gussy it up with suspension forks. You want to make this thing look as plain and univiting as you can, to potential thieves. A rigid fork should work fine for you on the road. They work fine on road bikes, don't they? One less thing to worry about having stolen. You should be able to find an older dirt bike rigid for "dirt cheap", if you will pardon the pun. Everybody wants to have Boinger front and back ends on dirt bikes and that makes what you are looking for really cheap. Just my 2 cents.

Dupliner and herculiner.
Both suck. Lot of prep work. Durabilty is average to poor. Doesn't go on thick enough.
I've used both. Herc needs about 4 coats to get it thick enough. Dupliner just turns flakey.
The spray ons are almost rubbery: would seem great for locking up.. etc.

rhynoliner.

works pretty well. they had it on some of the trucks at the park district i worked for for a summer. we put those things through their paces. even had two of the mini-dumpers the stuff lasts GREAT. it dries hard a
and stays hard. i'm not sure that you could get them to coat a bike though...

There used to be something called Zolotex or something like that. It looked kind of black and white and really rough. It was around in the 1950's when I was into hot rods. I don't even know if it is still made. Check with an auto paint store for their suggestions.

cadmium yellow?

[the same stuff they paint bulldozers with]

Why don't you just dip the frame in a vat of that rubbery stuff for tool handles?

That is awesome. I am gonna do it to my arms.

hmm...is that stuff hot, or is it something that you mix up a batch by combining two chemicals and then it hardens?

Don't know, but it sure is tough. I used to work at a place that made motorbike stands; they had these 'cups' that sit under the rear swingarm (attatched to the stand of course), coated in rubber, I never saw one damaged (lots of old ones lying around the place).

But regular powdercoat is pretty good stuff, comes in a zillion clours and it's pretty durable.

That's two posts in a row you made me laugh out loud!

I've seen the ultraheavy-duty rubberized paint they use for road striping around in cans someplace, too... might work!

I'm gonna shave my head and dip the dome. Paint on some hair and never worry about a helmet again. CPSC be damned.

They sell that kind of stuff for tool handles in aerosol form, too. It might be a good covering.

This would combine the effects of fixed gear fever with white line fever. A truly scary concept.
