Locks that work

GA2G, do you have any views on the Abus Mini 401?

From what I can gather this is a relatively recent Abus lock (it's not on the Abus website) that features a 16mm shackle in a portable package. The capacity is slightly less than a Evo Mini (83mm) at 75mm but having had a play with it I reckon it will fit around a sheffield stand and through a rear wheel and seat tube of steel frame bikes with fairly tight clearances...as long as they don't have deep section wheels.

It looks like a good choice for primary security if you don't mind being restricted to sheffield stands and you don't have deep section wheels. What do you think?

It's discussed in this thread a few pages back.
