Ergon Grips
I've have Ergon GR2 Grips and bar ends fitted on my Marin MTB. They certainly give a very comfortable cycling position. They may be a good choice for Agattu/Pro-Connect owners who don't like the look of their swept back bars but don't want to lose the comfortable riding position that they offer.
The only downside I've found with these grips is it's not easy to fit a mirror, I have a small strap on Zefal Spy Mirror fitted but it's not as good as as the larger Cateye one on my road bike A long stem one might work but would probably spoil the look.
