So I bought a new bike a couple months back, and opted to spend the extra $$ to add the carbon rims. They are Vision SC40 TLRs. Nice enough rims, but in my never-ending quest for "the next way to reduce resistance", I decided to look into upgrading to ceramic bearings. I like the idea of the decreased resistance, and more importantly, the longer bearing life. Pulled my hubs apart to get the bearings sizes I'd need to shop for. Lo and behold, the front hubs have 18x28x7 bearings. Searched everywhere, contacted all of the well proven ceramic bearing sources (Boca Bearing, Ceramic Speed, and others), and have found out that ceramics aren't available in this size, which leads me to think that FSA put bearings into these units so that you can't upgrade your rims to "match" comparable Zipp rims. Just an assumption on my part, but I can't figure any other reason to use a bearing that isn't "standard" fare for this application.
That being said, does anyone have a recommendation that would be a high quality replacement for the stock bearings? Currently all bearings installed are "S&S" brand, "2RS" sealed bearings. Does anyone have any info on brands and part numbers that would be high quality upgrades for 18x28x7, 17x28x7, 6803, and 6903 bearings? Looking for "non-contact" seals, low rolling resistance, and good bearing life. I ride road, and live in an arid climate, so not worried about mud/gunk intrusion, etc. I can find the stated bearing sizes in steel everywhere online, so I'm looking specifically for brand and part#s so I know what to look for, based on people's good experiences.
Thanks!
