had Mary bar and currently on Carnegie..
the mary was really good, once you adjusted to it I personally found that the narrow (ish) backswept position gives more leverage when pulling.. If you’re really trying hard to pull upwards on something you have more leverage with a narrow grip right..?
Imagine trying to pull up on something off the bike.. you don’t spread your arms wide to get more leverage you bring them closer to your body..
I really found them them to be quite an aggressive bar.. no problems on severe rocky tech trails at all.. the Mary feels like you just use your shoulders and arms to do the work rather than your whole upper body, leaving you with more options regarding body position and weight distribution..
I tried the Carnegie to see what all the fuss is about wider bars.. hmmmm… the jury is still out for me.. I don’t find the wider position so aggressive as the mary although it feels more natural and comfortable over distance.. I’m more confident with it but then suddenly don’t feel so in control when things are right on the edge..
