Guess I could upgrade my old dh tube style for the real deal
Yes, you should. Zip ties scratch your fork and you have to cut them to get the flap off.
Tested today in some thawed depth hoar on Green Line. Exceeded my expectations. Probably a 90% reduction in mud-in-the-face, compared to no protection. Seemed to work better at higher speeds.If you don't like a goofy, plasticy thingy falling off the front of your then this is what you've been waiting for.Light, cheap, simple and effective.
A shroud works well in addition to these for really wet conditions.
