Mountain Biking - Replaced Crunchy McSquishybike

So I finally pulled the trigger on a bike to replace the one I drove over with my truck

2008 Kona Dawg Deluxe, on closeout.

I was thinking I wanted more of an XC bike to try to make up for my spindly legs (I don't really do much in the way of drops) but this thing was such a bargain that I couldn't pass it up.

Nice, don't run this one over now. ;)

I'm gonna try to bend back the frame on the old Dawg. Any tips on that? I have a vice on my workbench...

Don't bother since it's an aluminum frame. Even if you get it back to normal, it stands a higher chance of failure since the metal in it will be permanently weaker than it was new.

It's trash anyways, and I've got a new bike. I've got nothing to lose.

seems aweful close to the truck.

nice bike.

take all usuable stuff from the old one, and scrap the frame.

see what you can get for it from a scrap yard lol.

Very nice . . . enjoy that Dawg.

Use your vice and then play with a set of Pony clamps as spreaders and such. Put some pipe or solid bar cut to 135mm between the dropouts and clamp that part in the vice. Then start jacking around the other stuff, measuring triangulation as you go, and see if you can get things back in alignment. Just always try to use slow pressure and leverage instead of brute hammer force. Use your imagination of stuff around your shop to exert the leverage/pressure you need. If you have a Porta-Power set and/or an arbor press, all the better.

agreed. lol

yeah but wouldn't you feel silly if you lost some teeth cause your old bent bike gave out on you when your nice shiny new bike was sitting at home?

Being a bit melodramatic, here, aren't we?
after looking up melodramatic to clarify, no, I'm just saying you got a nice new bike, why would you try to bend an old aluminum frame back so you could ride IT instead?

especially since AL doesn't have a good record for that kind of thing.

You can also use a few 2x4s to reinforce the spots that look like they are weakened and potentially apt to failure. I think. Well, scratch that. I'm bad with this kind of stuff.

Or maybe I'd like something to give to friends for occasional trail rides together? You act like I'm going to ditch the new bike for the old one and go bombing off some 8' drops. I have an otherwise decent bike, it won't cost me a dime to mess with it, there's no reason not to.

Not a bad idea, I'll see if I can bum a set.

Well, scratch that. I'm bad with this kind of stuff.You are. That's evident. Shut up. :D


There are even a few little things one can do if tweaking things back in line causes a crack or two. But I'm not going to mention them here or the doomsday scenarios will really start to crawl out of the woodwork.

just put the truck in reverse and back over it again. duh.

You could have a KONA TOSS, similar to the traditional HUFFY TOSS.

^ Now, if the guy was deliberately aiming for the photographer I'd say that's a pretty respectable toss! I wonder if the camera survived?

Replaced Crunchy McSquishybike...

McSquishy?!??


Is that medical drama TV series really that popular... :lol:

Actually, I thought I made that up.

what a dick move
If a friend needs a bike the only respectable thing to do would be to let them ride your new one and you take it easy on your old one. If a friend let me borrow a bike that he knew had structural flaws, especially fatigued aluminum, and it failed while I was riding it.... I would not be happy.

Communication break down?

entirely possible, I'm frequently a moran

It's trash anyways, and I've got a new bike. I've got nothing to lose.

A few teeth, maybe? Aluminum does not bend and hold its strength, period.

Just hang the frame in your garage or den or something. Don't be a tool and try to bend it back so that it is "ride-able"

Sheesh.

Take another look at the OP's wrecked bike, you guys. I guarantee that it will be impossible to get the frame even close to rideable.

After heat treatment and hardening, aluminum used on bike frames isn't like steel which can be cold-worked back into shape. When T6 aluminum is bent it starts to fracture even if sometimes it can't be seen at the surface. Strongly advise not to reuse it.
