bent dropout question

[Rebel_Biker]

I bent my dropout on a Pinarello Bassano. Do you think this can be fixed by cold pressing? Thanks in advance for any advice.

Nice to be working with steel. :p

If you can bend a tweaked derailleur hanger back into place I can't imagine this wouldn't respond to the same technique.

I would use an adjustable wrench (with some appropriate protection for that pretty chrome) and gently go at it.

But, I'm sure some others here have already actually done such work on track bikes...

You should be able to bend it back. If the job needs a hammer a rawhide mallet used in the jewelry trade will let you whack it with out leaving a mark. They are more controllable with a better impact than a rubber mallet.

thanks guys

I will use the advise an bend it back.

One thing to think about is why this happened in the first place. It can happen when the built in floating washer on the track axle nut freezes to the nut itself. This means that when you spin the nut it also spins the washer which then grinds against the dropout which in turn can spread the slot.

Make sure that the washer does not spin when you tighten the nut. A bit of lube (chain lube works well) placed between the washer and the nut can work wonders.

Good luck.
