Demoed an ST4 – my personal opinion is that this bike only makes sense if you can afford to pimp it out.
The biggest problem with the ST4 is the Orange Five. The ST4 isn’t really any lighter (6.8lb vs 6.4lb for 18″ frame), it feels like you’re riding a Five (sit on one blind folded and you’d be hard pushed to tell), only it’s less capable on the big stuff (that’s not to say it isn’t capable).
It does pedal better, there’s a remarkable lack of pedal bob and they could save money by fitting a basic float shock.
Where the ST4 would make sense IMO is if you pimp it out. The Five is always going to be limited to a heavier 140mm fork. I reckon the ST4 could take a 100mm fork instead of 120mm so something like a SID and some racier wheels and you’ve got yourself an awesome light but tough alldayer.
In S and Pro spec, you might as well bag the Five.
So to answer your question…
an Anthem?
