I am confused by REI's product name and tech specs for bicycle ABUS chain locks. You have 2 ABUS chain locks for sale, both called Granit CityChain 1010 with lengths 32" and 42". On ABUS web site, they have nothing by that name. They have CityChain 1010 at 9 cm thickness and also Granit CityChain XPlus 1060 at 10 cm. Which level is REI selling? Also, your 2 weights do not match ABUS weights. You list the 32" at 5 lb 2.9 oz and the 42" at 5 lb 4.7 oz - that is only 1.8 oz difference with a 10" longer length. Please advise your corrections - name, thickness and weights - so I can make a confident purchase decision. Thank you.
