It's actually pretty hard for a stick to get through the spokes of a wheel with a reasonable spoke count. Not impossible, mind you, but difficult. I've flipped sticks into one side - snapping a spoke, but never all the way through. (Mythbusters actually did a good segment on shoving a broomstick into a motorcycle wheel - but speed was quite different.) Good reason for 32h or 36h setups...
The great squirrel-snapping-the-front-fork examples (more than one, curiously. quite googleable.) are from very low-count wheels. It also provides a good contrast to how different materials handle super-high-stress impacts. Back to the example at hand. I've seen accordianed rear plastic fenders a few times, as those tend to not have the QR's. If you roll a lot of mixed terrain, you are liable to pick a stick now and again. It happens much, much faster than you would think. At one point, I sketched out a paisley-shaped doohickey which you attach to the trailing edge of your fender and then could point/angle to prevent this. Never took the time to bend something up. The more critical issue is the clearance of metal fenders. The sobering example in those photos is that it's worth tuning the fender line, and that it isn't just for aesthetics. Given the bend - which would tend to occur below the jam (fulcrum) where the metal thins out - it does seem that it happened right at the top of the tire. Front tire stoppage is scary stuff in my book. Stay back, stay alert and ride safe, folks! - Jim cyclofiend.com On Thursday, July 25, 2013 5:55:50 AM UTC-7, stevef wrote: > > Yeah, scary pic.
