A little? They're 2.3kg! They are amazing frames though, probably the best frame I've ever owned. If I ever get another mod it will probably be a Zona. (Heavily modified to save some weight!) They maggy mounts are really deep though, if you get longer bolts and cut them down to fit, you can get over 10mm of thread inside the frame, so you'll have to be incredibly ham fisted to strip them. Mine was 1070 with T-Pro forks and a knackered chain, 1045 with Echo Lites and the same chain, so with a nice new chain it should be about 1040 with decent forks.
