Really enjoying mine. It's only got 140mm Revs on it, but a real blast to ride. Previous bikes have included a steel Inbred and a Patriot for reference.
Good points:
Wonderful spring to the frame which I guess is a factor of being steel, but also clever engineering.
Steep seat tube makes climbing easy for this style of bike
Weight – not sure what mine has built up to, Revs and XT kit but it doesn't feel particularly heavy
Downhill it's a complete giggle, that slack head angle makes it really capable and with the edge taken off the trail buzz through the frame, you can really let it rip
Pedallable – it's a really easy bike to just take anywhere, and will go up and down most things well
Not such good points:
Flat singletrack – this may be me just not getting it fully dialled in yet, but on flat singletrack it doesn't feel as precise and I'm more prone to the front end not holding in there as well as a steeper angled bike. As I say, it could be just me not getting enough weight on the fork at this stage, and I don't have the problem when pointing down hill.
Blanking/Cable Guide bolts – the aluminium is very, very soft so be gentle when tightening them up.
Overall I am really, really enjoying it and would definitely recommend it. It's substantially less cash than many rivals as well (not all I admit), which also helps.
