Bike Project Part VIII

Finally got the spacers and cog.

Just spent a few hours today trying to figure out how I'm going to set them up to get a good chainline.

I measured the chainring position, rear dropout spacing and splined freewheel mechanism dimensions last night. The spacer kit recommendation is to suit new style 135mm MTB or 130mm Road bike dropout spacing, but mine's a late '80s 126mm with a narrower freewheel mechanism, so I drew up the measurements and calculated the spacer and cog positions.

And I think I've sussed it!

So I'll maybe have a go at that tonight.

Next challenge will be to set the chain length so I don't need half links or tension devices to mess things up.

Then finally to rebuild the wheel bearings.
