I got my Ergons awhile ago and initially used 'em on my Dahon. I use the original ones and cut the right grip down. Oddly enough, they seem to work a little better with a more upright position; on the Dahon the bars were 3" above the saddle, on the Swift they're even, so I assume I'm putting a little more weight on my hands now.

The bar & bar ends are both Nashbar brand, just the 580mm flat mountain bar and their bar ends. Maybe it's just my imagination but the handling feels a touch more solid now. I'll post pics at some point....
