Agree, all depends what riding you like. No need for steel frames, alu is everywhere (and personally I can’t see it’s worth spending a mint on carbon). Choice is more about the right kit for your style and budget (wheel size, gearing etc)
I was in the same boat until yesterday with 2 older (2009, 2012) bikes both becoming harder to keep going. And then I was in Blazing Saddles in Hebden Bridge yesterday and they had last year’s Spec Camber at a v good price and right spec for me (2×11, decent kit level, etc). Only thing – I’m not convinced about 29er and had not looked at Spec models recently but too good an opportunity, so I’ll be out on it in a couple of days 🙂
Lesson – don’t overlook the obvious. And there are other 2017 bargains out there. Get going before the weather picks up and they are all gone.
