Everyone knows that Chris King is the most respected manufacturer of finicky components like headsets and bottom brackets. CK has been killing Shimano-compatible components for years, so it's great to see the SRAM Mountain Bottom Bracket, which packs the same quality into a BB that's compatible with SRAM, Truvativ, and Bontrager GXP cranksets with stepped 24mm axles.

The cups hold 24 stainless-steel balls in each cartridge bearing, and have King's awesome easy-to-clean design—to clean them, just squirt in clean oil and it'll do the rest all by itself. You can change out thicker and thinner oils in the same way, so you can usa a lower-friction oil on race day and a heavier-duty liquid for everyday riding.

Having an issue with a stock Omnium setup...

Having an issue with a stock Omnium setup on a new road commuter build in that the back of the spider comes in contact with the chainstay. BB shell on the bike is 73mm - hence the MTN type BB. Seeing as the BB has spacers, can I use...say...five 1mm spacers for the required clearance on the spider (and not have to worry about it still hitting when the crank/frame are under load)?

Any feedback is appreciated.
