The anti-klunk? (Show us your urban bombers!)

[mrfritz]

I don't know why more people don't do this. Most of your energy is wasted just pushing the knobby tires.

Strange, I've always felt knobbies were easier to pedal on then smooth street style tires, alot let less road contact due to the knobs only touching, I have knobbies on quite a few of my cruisers for that very reason. We may have to contact myth busters about this one.

Once you roll on a full inflated big apple you're mind will change, mine sure did. The 2" in particular really rolls... and in a 29er form factor it's not doing much turning to make distance either! I'm also pretty impressed with fully inflated hookworms on pavement.. And they are plush riding..

thanks for helping me out there

You might have less contact area, but those knobs squirm and deflect a lot when they roll into the contact patch. The energy they absorb in moving around outweighs the reduced contact area, generally. Slick tires and street tires with shallow tread blocks have a lot less deflection when they hit the ground, so less energy is absorbed and rolling resistance is reduced. Less tread squirm also means sharper response and better grip on hard surfaces.

This is a mockup of the second one I'm working on. This is a 26" rock hopper that I put a 8 spd nexus on the back and am putting a voodoo rigid front fork and 29er on the front. I'm hoping the fork and new bars show up in the next day or two so I can complete it. The derailer will be replaced by a tensioner and I am planning on retaining the front 3sp chain ring. If it works out at some point I'll strip it all down and make a custom out of it.



Bikes are FUN!

I need to quite using my living room as a shop and garage.

sweet! man that front tire is stuffed in those forks huh? lol looks good, re post a pic after the 29er forks...

I built this one and place it on the klunker gallery but I built it with smooth tires, bmx bars and a SA internal 3 speed.

I use first gear when cruising around the beach but use third gear when I want to ride from one place to another with some speed and that's when the tires come in handy. Running them at 60 psi.

In what category would you put this one?

1.5" street tires on my '89 Supergo Access Comp I've owned since new. Columbus tubing, made in Taiwan; go figure.

this is my crappy winter roads training bike - not so much an urban bomber.

a while back there was this car trend where you took a bigger personal luxury type car (grand prix, monte carlo, etc) and made a hot rod out of it. they called them gentleman's hotrods. your's could be a gentleman's klunker

FUN!?
Classic Cantilever Framed?
Rat?
Urban?
Bomber?

I'd call it a FUN Classic Cantilever Framed Rat Urban Bomber.

I do this to my bikes. I wish I had a pic of my 83 schwinn probe. It had a kenda kwest on the front and a kenda 838 on the back with a schwinn letour crank. The wheels were deep v's off a mongoose. So I stuffed a 7speed in the back. That thing was quick. Now i have a mongoose deceptio., lotus pegasus and the schwinn henderson to do. Not sure about my columbia trike.

I like that name also but that's not a cantilever frame its a dx frame!

How about UBK for Urban Bomber Klunker

[flatflip]

OK, I stole my wife's tires.

I'll update this post with better pictures when I have some daylight to work with. I'm calling this on the "2629 Urban Bomber" it started out as 26" mountain bike. I swapped the front spring for a rigid 29er fork and fitted a 29er rim. Right now the gearing is a little low with the Alphine 8 speed all I've had any use for is the 48t ring using the 20t cog. I'm going to switch up the to crank with a 38, 52 rings and a 15 or 13 cog.



It is an absolute blast to ride...
