Strengths: Light as you want. Fantastic to look at, clamping is very clean and simple. Manfacturing tolerances are very good - just eased down the steerer tube.
Weaknesses: Not front loading. Clamping of handlebars looks a bit skimpy in this day and age. The circular edges from where the handlebars meet the stem are not radiused and could be a stress raiser?
Overall: Damn fine but not for brutalizers. Expensive but lightweight.
Strengths: It looks great, its light, its strong. It's Pace.
Weaknesses: none as yet.
Overall: I don't know why people complain about the absence of front loading, because this doesn't affect anything -I use riser bars in mine and they fit in and out fine. Its worth the money 'cos it's a classy, well designed piece of kit.
Strengths: Well, they help a British company make money, oh, and they keep the big boys who like there toys happy. The ride felt okay though.
Weaknesses: The bar clamp breaks, maybe it's just me but I think they're way too expensive, tend to be used by people who think they're pro riders, but aren't.
Overall: I would go for a control tech or azonic, better VFM which is rare in MTBing these days. They both front load and are strong without being heavy.
