Does as expected allowing chain-line fine tuning

I recommend this product
Consmay be necessary to adjust the pedals!
Prosallows fine chain-line adjustment, easy to use and fit
Easy to install spacers that fit a cartridge type Bottom Bracket perfectly, I needed my chain line to be moved slightly, and as these are measured at 1.5mm its possible to change the chain-line precisely.
They are exactly 1.5 mm in thickness, measured using a calliper gauge. using multiples of these will enable larger chain-line movement, but be aware that too many will reduce the thread length of the bottom bracket! it will also expose the non drive side to dirt and water, where the threads are normally covered completely. this is not a real problem, just be aware. and it may also be necessary to adjust the pedals with spacers as they will move over by exactly the same width as the spacers.

Single speed freewheel

I have a single speed bike with a Dicta freewheel, can I use this to space the freewheel so that the chainline is better?
Hi there,

In theory, yes you could. But we would recommend looking at adjusting the chain ring position.

I need to space a Sturmey archer freewheel BSC 1.37 x 24 tpi out from the hub a little will these fit ?

The internal diameter is 35mm and the external is 40.5mm so these should fit on your hub fine.
