Hi everyone. I'm really new to this and Sheldon Brown's website has been my religious text for the last few days but I have a question I haven't found the answer for.

I'm searching for a flip flop hub. The rear dropout spacing on my frame is 126mm.

If a hub is too narrow, is it possible to switch out the axle for a longer one to accommodate wider dropouts?

It's made of steel.

Pretty much all hubs can be respaced to 126, but this might require a new axle. The reason Balki asked what it was made of is that, assuming it's steel, it's fine to use a 120 and just do up the axle nuts until it pulls the frame in a little. It'll only be 3mm each side.

OK, thanks so much :) I can go ahead an pick up a 120mm hub I saw at the local community workshop!

Hi TerryXL, I've literally got the same problem. I realise that you posted this a while ago but I was wondering how well the flip flop hub that was 120mm fit in the 126mm rear spacing. Any advice would be great :)

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
