well for starters the 21 does not have a ''slightly larger'' inflated tire diameter...i just measured several variants of 21'' and 19'' tire diameters...FYI,,,the average 21'' measures 28'' OA as opposed to 26'' for the 19'' set-up...that alone accounts for the smoother ride in the dirt
the 21'' front wheel assy is generically circa one pound lighter than the 19''s.. and with proper choice of hubs/discs/rims have been able to make them 2-4+ lbs lighter...now that is significant because that all equates to less un-sprung weight...which of course makes it easier to loft the front end and makes the ride more supple.
i'll need to get a more definitive ie scientific answer regarding what the narrower rim does [truth is i have customers banging at my door who need my attention NOW
] to be cont'd
excuse me for a few,,
