Just look at my MTB.
How do u feel about it?
I feel u are thinking about a Motocross bike.
Yes u R right, I just thought the same thing about this.
The fender costed around Rs400/ - which is quite worth than investing the money for a dry clean ;), a necessary for Rainy day where u can ride the bike with out fear of cloth being spoiled.
I just felt the front ones are working fine & there is need to adjust the back one a little upside.
Cons: The weight of ur Aluminium bike is increased by about 300 gms.
