$190 US, and took 3 months to arrive from Germany through the US supplier. They are well made, and the close-up picture shows they are adjustable for angle because of the interlocking feature of the pieces. The footpad angle is adjustable, too.
The drawback is that they place the foot outboard by an inch which takes some getting used to. Also, the first set sent to me were incorrect (not enough space to install the stock springs), and it took an additional bunch of emails and 3 more months to sort that out, but they did it with no complaints once I detailed the error.
The stock brake and gear levers can be adjusted enough. I had to remove the upper cam at the top of the gear lever rod to get the lever low enough as the rod adjustment wouldn't go far enough.
Overall intstallation including lever adjustment was a half-hour plus re-adjustment after test rides. The pegs themselves take 5 minutes to swap out.
As for function:
These take some stress off of the knees and do reduce fatigue.
Anyways, they aren't for everyone but there are some who might be interested. There are different kits available depending on how much "throw" wanted. These are the 30mm kit. Colours available, too.
