I assume that these are the brake levers that you are interested in...



These are just fine to use, provided that the wheels are true so that the brakes can be set up properly. Also, ensure that the "turkey levers" (not my choice of terms) do not hit the handlebars when used.

I don't know of anyone who has these for sale but if you wish, you are welcome to send me a private message regarding availability.

Hope this is a help.
