Chain Length

[Dan_h]

Hi Guys,

On my bike I have a 48 tooth chainring with a 17 tooth fixed cog and a 17 tooth freewheel on a flip flop hub. Does anyone know if it is possible to run a 17 tooth fixed with a 19 tooth feewheel or would that cause issues with the chain length when i flipped the wheel? Currently i need to pull the wheel back about an inch and a half in the track ends to get the tension about right.

I have done a few hilly rides recently and the ability to get a bit of extra leverage when feeling a bit tired would be good!

For every increase of 2T either front or back the rear axle should end up moving forward by a quarter of an inch. You have plenty of leeway.

... however, you may need to adjust your brake blocks (assuming you have rear brakes like you should when running freewheel)

That is cool, thanks.

i certainly do, I am way to scared to ride without a rear brake!
