Hey guys....bought a threadless steel fork from Soma. Next issue is the handlebar stem. Most are made for 1 1/8 diameter. I see that JensonUSA sells a "shim" to address that. Any concern with that? I wouldn't think so. I can also fabricate something pretty easily. Also, what's the skinny on "ZIPP" products? They sell a nice looking silver colored stem. Smelly, I need to hear from you on this! Thanks!
