210 and gravel (old fashion tracks)

[hottuna]

Had my first outdoor race with the 210 last day. It ended up with a big disapointment.
It was on a dirt track, loose gravel. On all 3 quali rounds, and 2 out of 3 final rounds i got small stones stucked in the rear rims.
I know it happens all rider sometimes, but not this often. I have had other brands, and never had this problem before.
I noticed the clearance from hub to rim is almost none, all small grit stones got stucked there.

Anyone else noticed this? And have Durango really tested the 210 on gravel?? Or has the turf, blue groove and indoor made it forgot about us european racers who still uses the original buggy tracks?
