He's talking about a
heavy-load-capable TOURING bike, folks!!
NOT a "racer"...or a "sport-touring" model...or a MTB!
For a touring...or utility (city) bike, a kickstand is really a
necessity! Trying to put a heavy cargo load on ...or attach a trailer to...such a bike WITHOUT one can be, at best, "interesting", shall we say!
As for the problem of kickstand attachment to a Trek 520 touring bike...I feel for you!! I HAVE a Trek 520...indeed, the ONLY place a kickstand can be mounted, reliably, IS on the chainstay/rear triangle!!
There IS NOT enough room for a center mount model of any kind!!! Especially with full fenders!!
What Trek was thinking...I don't know....
Also...
weight-weenies DO NOT RIDE heavy-load-capable touring bikes!!!
