Don't get the carbon chainstays if you're above average weight. I found them too flexy (Mine was the previous model, with the 'hole' in it) and I sold it mainly because of that.
Otherwise, lovely bikes. Superbly made, tough paint, superb mile munchers (I did the Trans Wales on mine) and they climb well (You need to use the ProPedal switch a lot though) Not as supple under power as a Spesh FSR either, the back end 'digs in' rather than following the terrain like an FSR. Quite a high up bike too, no pedal strikes
I did find they need very careful set-up too. I've never had a bike that was so sensitive to tiny changes in set up before – Suspension, tyres, setem length, anything.
On the whole – Lovely bike, but an all day limmo, not an all mountain hucker.
I swapped a Stumpy FSR for my 575, then went back to another FSR (Pitch) because I prefer them, but that's just my opinion.
Compared to an Enduro, it'll be lighter, quicker, and higher up, but not as capable when the going gets tough
What sort of riding do you do?
