For SLK, Just to be really depressing!
The ideal distance between the centres of the front and rear sprocket should be between 30 and 50 links
With a 10 tooth front sprocket (I race Blue) and
a 30 or 31 link centre then the chain should be n links long.
eg: for a 70 tooth rear sprocket and a 30 link centre the chain should be 103 links long
at a 31 link centre the chain should be 105 links long.
Obviously you adjust the chain centres between 30 and 31 (a distance of 7.774 mm) to use 104 links

For Matt. This is a simple(?) application of trigonometry, IT (google) and Excel...there's a use for that school work.
