Chain length?

[dmgraham8]

Hi cyclechatters,

I have put a new chain on an old Raleigh. I don’t have the old chain.
How do I gauge the correct length of chain? It’s probably a bit loose at the moment.
Also, new shifting cables are going on. Any tips/things to beware of would be greatly appreciated!

thanks in advance,

Without going through the derailleur wrap the chain around big ring and biggest sprocket. Pull tight and add two links.

See parktools they have 3 methods

I think your QR lever would be best on the non drive side.

What crankset is that, dmgraham8?

Hi Ajax Bay,

It’s a sakae SA, entry level apparently - more pictures here:

See my comments on that thread. It's an SR Sakae btw, and 'entry level' is unkind, imo. A UN-300 BB (correct length spindle) will be a good replacement if the BB is rough, though a good clean out might do it.
Recommend replacement of the outers as well as inner cables (especially the loop to the RD).

This, dead easy and works every time.
