Impression after first ride. I love them......
They replaced straight bars which had too much of a tiller effect when going slow uphill - I meandered all over the place. Now I don't.
They bring my hands closer to me, so I'm a little more upright and less bent over. I like this.
Main hand position i.e. holding the grips, feels entirely natural: the Rohloff twist grip is very easy to operate and the brake levers are within easy and instinctive reach. No wrist pain.
There's no knee contact.
Lots of alternative hand positions and space to put lights and other gadgets.
I may have just found my perfect position.
