Alta Safety Washer Hub - Heavy Duty Front Wheel Retaining Clip for Bikes, ATVs & Motorcycles | Secure Wheel Fastening | Off-Road & Commuter Use

I noticed that one of my bicycle’s had a regular washer On the front. I also remember one if my guests going on a bike ride, and having the front wheel cone off while riding. Luckily no injuries,But these washers keep the wheel in place.Highly recommend.
