the echo hub is... well all fixed cog hubs right now are WAY overpriced for what they are. the echo hub uses cheap bearings, a cheaply made hub shell, cheap axle, super cheap cassette body.... the whole thing is not very high quality stuff. the try-all one is much nicer but is still nothing to write home about. Just my opion there are plenty of better hubs out there.
Hope ive helped
