New Charge line-up

The movement of the BB was a hidden benefit to me when I had one and allowed fine tuning of BB height. Although the difference was small admittedly.

I'm with you though, if not using discs then track ends for me every time (light, reliable, least complex and look the best)

A EBB also makes life easier with bikes/frames that can be run with or without a rear mech. Because you dont need to re-aline the rear mech each time you remove the rear wheel. Vassago had a neat solution to this though. A separate mech hanger that threads onto the rear axle and into the track end in the same way a chain tug does. Means the mech is always alined yet the bike look cleaner when running it single speed.
I've gone for the simple slotted disc caliper mounts for my SS offroad build but then as its a belt drive I'm hoping not to have to adjust tension as the belt should'nt stretch (special chain tugs should insure that the wheel sits in the same spot after removal).
