Thanks dodge, The fender looks closer than it actually is. At full compression there is 1/2" between the tire and the end of the bolts. And even though I've tried it hasn't come close to fully bottoming out while riding on a rough trail. Of course I'm not Evil Knievel so the bike has not been beat on too much! The way I tested this was to put a zip tie around each fork tube. And then I went for a ride and then measured the distance the zip tie moved. Low tech I know, but it worked!
