Bought one of these online, got it for 49 bucks which was the best thing . I will say this is a good product it keeps the water from splashing on your back while riding the bike at at high speed. However it doesn't look very pretty on a hybrid or Roadbikes (700c) , but it's super easy to install and uninstall and storage is the best part as it can get completely flat and can be stored anywhere. The plastic Quality is way better then it looks online. The Zip tie belts given to secure the mud flaps is excellent coz u can unlock it when needed it can surely stay in place even on trials and mountain biking. The best part is it won't break in case of an crash . It will just flex . Highly recommended product.
I have been using this Mudguard on my roadbike. It was on sale and got it for just Rs.49.00. I found it to be very effective and reduced spray from rear wheel . It is strong enough. May not stand rigors of hard MTB off roading.
