Considering ride quality and speed.
I've found two or three opinions online favoring the Bridgestone over the TSR--and none expressing the reverse preference.
I've ridden a separable TSR 8 that was simply too bouncy, and an AM Speed that was horrendously perfect. I'd like to find a less expensive alternative to the non-TSR Moultons, but it's unlikely I'll be able to test ride either a Bridgestone or a non-separable TSR. (This is off-topic, but: I'm unsure why the TSR and the AM Speed rode so differently--because one was separable? This was what the dealer emphasized as the most likely culprit. Or because one had "racing suspension"? Or because one had smaller wheels? Or because one had drop bars? Or because one was $7K? In any event, they couldn't have felt more different.)
Anyone ridden both, and come away with a clear preference?
I'm also curious if anything was ever done about the Bridgestone's cracking issue. I'd probably be interested in a nonseparable version, though.
