two bolt kickstand source in USA?
There seem to be two (German?) standards for kickstands that use two M5 machine screws instead of one giant bolt: 40mm apart and 18mm (17mm claimed on some pages). I've found two manufacturers: Hebie, who makes the 661 and 662 for 40mm and Esge/Pletscher which make the Comp and Comp Zoom for 18mm and Comp 40 and Comp 40 Zoom for 40mm. I think "zoom" refers to an adjustable length leg.
bikefront.com sells the Hebie chainglider, but only lists one kickstand (a two-leg centerstand) and lists it as out.
HP Velotechnik puts 18mm holes on the Street Machine & Hostel Shoppe sells the Pletscher Comp for $36.
Thor USA has the Pletscher Comp Zoom for $24 for Dahons.
Specialized puts two bolt kickstands on some of the Globes & older Crosstrails. It looks like a Pletscher with the "one less car" symbols stamped on it. it also looks like 18mm.
I'm going to try to get my local Specialized shop to sell me one, but I sure would like a stand with 40mm spacing. I have to fabricate a mounting plate anyway, so I might as well make it a little bigger & stronger, though still a lot lighter than the monster plates the single bolt stands use.
