For any who might be interested, I have a Suntour Superbe brakeset for sale for $55.00 with shipping in continental US.
They have a nutted attachment, reach of 50-60 mm; calipers are in good condition; one lever has road rash on the side and both have other scratches. The levers have black Ame hoods.
Jpegs should you want.
Thank you.
Cheers.
