Kevin, You mentioned that if you get the 16t Middleburn, then you should run a BMX style chain due to the low coverage of the bashring. Do you run one of these chains? Do you run a king hub w/ 9spd cassette? The reason I ask is normally a BMX chain is much wider and not compatible with other systems. Hell, it's hard to get an 8spd chain to shift properly on a 9spd cassette nevermind a super wide BMX chain. Ken T.
