To all you 29er's out there!

Looks like you have 3-4mm of thread protruding through the dropout, so a small washer between tensioner & dropout will be fine. Just be careful how much of the quick release skewer is held in the part above it.

almost all of it!

and the clearance is a little better...

might even go for thicker washers if I can find any, just to be sure.

cheers for help.
