Snapped frame help please

Hi, I was fiddling with my gears because they weren't changing correctly when I noticed that there was a snap in the frame near the drop out. The bike also shakes vigorously when I brake hard, could this be why?



Is there a way of repairing it or is it better to sell it for parts and break it and buy a new bike?

Thanks

Too little information to make an intellegent reply

Too little information. What frame material (looks like Aluminum)? What year, brand, and model bike? If you bought it new, there may be a warranty on the frame. Got to the manufacturer's website for warranty info if you don't have any material that came with the bike. Some frames are warrantied for a few years and others for the lifetime of the original owner. Most times if the bike is second hand, there is no warranty. You might need proof of purchase if there is a warranty and it is still in force.

The bike is a Carrera Crossfire 2, on Halfords.com it says the frame is made of lightweight alloy. I bought it second hand so i have no warranty.

My dad said he'll be able to fix it but I want a new bike, I'm going to be paying for it but he wont let me have one unless the current one is completely done so how can I intentionally snap the frame? Thanks

a repair is not likely to affect anything that is not near the repair site

a repair however
probably a weld
is likely to be considerably weaker than the frame was originally
so if your dad welds it back together
just ride it and it like you were before
and it will probably fail again

as for getting a new bike
you don't need a new bike
just a new frame
and if you shop around
you can get a new frame of the same or better quality
for around 100 dollars us
or whatever that works out to in pounds

I would like a new bike though, this was my first bikewhen I got into biking so I though a hybrid would be best for me but I realised I need a mountain bike now I've got a hybrid. Is there anything I can do over the skate park that can weaken my frame, I cant flare or whip or anything so if its complicated I wont be able to do it ��

Is it out of warrantee? the shop you bought it from is who you ask nobody here can do anything but writer condolences ..

looks like those holes in that frame portion under the Disc Brake caliper was a Stoopid design.


shop for the next bike at someplace that is not mostly in Car Parts.

Yes it is out of warranty because I bought it second hand and yeah I still don't know what those holes are for...

Anyone know anyways to weaken the weld where it has been snapped? Or how to weaken the frame and make a new snap I can the break the bike for parts, that will then give me more of a budget.

If you're really budget-constrained, get just a new frame and swap everything over.

That frame is pretty much toast. Don't begin to think for a moment it can easily be welded and safely repaired.

It snapped from metal fatigue and having a hole there didnt help .


If you have to hire an aluminum welder ,, after stripping it down and reinforcing that area with more metal also welded in

You may be able to then rebuild it and get it working again, for the cost of another Chinese imported Bike, just like it.

Kinda like C'dale Hooligans


I'm thinking either a defect or abuse caused the break,not the design.

It does look like aluminum - take a magnet to it to be sure. A magnet will stick to steel but not aluminum. As you have learned (the hard way) aluminum fails catastrophically - all at one time unlike steel which usually gives you some warning. A shop can heliarc weld aluminum but as others have said it probably is a lost cause. If it broke once it may break elsewhere. This bike would be considered "entry level" at a bike shop in the US. I've bought a couple used aluminum frame bikes in the past but they were way more expensive bikes to start with and I didn't pay much for them so I wouldn't be heartbroken if one broke.

The bike has seen it's last days and done it's last whip!

In most cases, you can't safely repair an aluminum bicycle frame with any certainty. It's too risky! Get another bike!

This frame is no more! He has ceased to be! 'E's expired and gone to meet 'is maker! 'E's a stiff! Bereft of life, 'e rests in peace! If you hadn't nailed 'im to the perch 'e'd be pushing up the daisies! 'Is metabolic processes are now 'istory! 'E's off the twig! 'E's kicked the bucket, 'e's shuffled off 'is mortal coil, run down the curtain and joined the bleedin' choir invisible!! THIS IS AN EX-FRAME!!
