I have seen recommendations and replacement swing arms 1" longer than stock for Cubs and C15s. The only description is that they work better. Could someone elaborate on exactly what this improves and how this may help on specific obstacles? Does it help the back wheel get over sharp objects like a vertical 12 or 18" step? Is it a significant difference or a subtle change?

Thanks,

or maybe to get more clearance stops mud cloging up?

a couple of basic principles i suppose.

a long bike is a stable bike in a straight line ( land speed bikes are loooong and hill climbbikes have four foot swing arms) on the other hand trials often mean going around stuff so a short bike would be req.

how does the length of the arm impact on suspension movement? a long lever makes it easier to lift an object, a longer arm may allow the suspension to be more laid down ala ossa and majesty

if nothing else is changed, lengthening the swingarm increases the front rear weight bias (heavier at front).

Depending on where the new bottom shock mount is, rear suspension travel can be retained or increased.
