The Lime alloy Scout from 2015 is what I have. I love mine a lot.
I started to get giddy when the carbon version was proposed as being the perfect upgrade for the alloy. I didn’t upgrade for the following reasons;
Could justify the cost over perceived technical advantage.
Didn’t like the fact that the down tube has a long curve in it. I prefer the look of the alloy version.
Once I considered it, I realised I don’t actually want a carbon bike. They are too desirable to leave anywhere and would attract unwanted attention (he says, after admitting to owning a flouro yellow alloy version).
I build my own bikes, my perception of carbon is that here is a much smaller margin for error when fitting parts, headsets, BB’s and the like. I don’t own any carbon parts on any of my bikes as a result.
