I’m in a very similar position so also interested in opinions. I’ve loved the Alpine, but it is a bit hefty and only 27.2 seat tube so limited on dropper post options. I also fancy trying a four bar (horst link) again.
I’ve got stuff to swap over so would prefer a frame only option, but considering a full bike and flogging the bits I don’t need. Currently narrowed it down to:
Lapierre Spicy (hopefully some good deals around soon on 26″ 2013 models)
Specialized Enduro
Nicolai Ion 16
I really like the Ion (good angles and get to choose shock), but it is expensive and I don’t think it’s much/any lighter than the Alpine.
