Bent pedal stem

[jido]

Hello,
I had an accident ramming into a car (the car won) and although I came out badly bruised myself, the cycle is fine.

OK I am lying.

There was a stone that found its way in the seat, which is slightly uncomfortable. And then there is the bent pedal, which is more of an issue for me.

Check the attached picture (no it is not the effect of perspective).

Now I have a dilemma. I don't have a sledgehammer lying around at home, and I am not even sure unbending it with a sledgehammer will do much good to the rest of the cycle.

So is there a better unbending tool I could use?
Thanks.

I would look for a new pair, straightening that would weaken it, it is seldom fun when a pedal snaps.

And your knee will suffer some damage.

Bent spindles wobble the pedal as it rotates, wobbling your knee joint. Never a good idea. I would also suspect the cranks after a whack like that. They snap along weakened areas generally when they can do you most damage.

Huh... The chainsets I can find online are on the expensive side. Oh well, at least there is not a lot of parts to replace.

Looks to me more like the thread in the crankarm has been ripped out, DAMHIKT
I'd replace it asap as I know what could potentially happen next if you 'sort' it.

What is the "thread" in the crank arm? As far as I can tell the crank arm itself is bent.

Bent spindles

It is not the spindle, but just as bad for my leg.

It does look as if the threads in the crank itself have been damaged.

A firm like Highpath can repair them

The steel pedal screws into the aluminium arm, an impact can rip the threads out of 2/3rds of the aluminium arm and leaves it still attached but very weak.

I see. The cure is same, right? I need to replace the chainset.

The one I have currently is a Tempo FSA

And the pedals.

 

[Crankarm]

My ears are burning. As has already been suggested check the crankarm for stress fractures and also whether it too is bent although it is probably cast and won't bend but just snap if it is a cast aluminium crank. Yes new pedals as well. Maybe new chain as well if the chain rings of the crank were quite worn meaning the chain may have needed replacing as well. It's not good putting an old worn chain on a new chainset. Also check out the sprockets of the cassette as well. If they are excessively worn replace the rear cassette as well.

And the pedals.

The pedal may have survived intact, it takes a lot to wreck them especially if its a CrMo shaft. The only way to tell is remove it.

You don’t say what your B.B. is but Decathlon have some good prices on cranksets, https://www.decathlon.co.uk/105-11-s-170mm-chainset-id_8311066.html this for £95 is a good buy compared to just £15 less for a Claris from Evans.

Since I have FSA I assume a square bracket.

I found the following replacements, will probably go for the cheapest:

I will also replace the chain and cassette. Hoping the pedal is still good.
