My good bud is looking for a 50cm bareknuckle frame. I've scoured CL looking for one but they are all 56cm and above. Is there a website somewhere that has them cheaper?

Citygrounds has them for 689 but I'm looking to spend less. It's odd. Usually I can find them everywhere but it seems either they are drying up (heard they are being discontinued) or something....

If anyone can give me a help, maybe a LBS or site that has them cheaper...or even a used one, that none of you guys know someone is selling that's in good condition let me know please.

Thanks
