I currently have a Shimano 5700 10 speed double 53-39 t crankset with BCD of 130 mm (http://www.chainreactioncycles.com/shimano-105-5700-double-10sp-chainset/rp-prod50439?gs=1&gclid=Cj0KEQiA-NqyBRC905irsrLr-LUBEiQAWJFYTkxMA9a_E1fL6-t7-aTW19bkJuJg-JSW1YW7l4VlWooaAuNz8P8HAQ&gclsrc=aw.ds).

Can I change to a Shimano 110 mm BCD cranks of 53-39 t (http://www.chainreactioncycles.com/shimano-105-5800-11-speed-double-chainset/rp-prod116491)? That's 11 speed but I don't think that will matter. The reason to change is I want to try a 165 mm length crank instead of 170 mm on current.

The BCD shouldn't make any difference to how the cranks work, just which chainrings you use. As long as the BB matches the cranks go ahead.
