well the way i am going to run my cc-01 is for rock cralwing purposes only so what ever i can throw at it. you know: water, mud, snow, the normal crap. i have been looking at protek bearings but they don't make every size i need. i would like to get all of the same bearing. i am going to keep doing some more searching. i have an email into boca bearing but they have not gotten back to me as of yet. but thanks for the heads up.
