Total newb - Fender questions!
I am new here and new to biking as well. I biked as a kid for fun but I want to get more into it for commuting and everyday travel so I feel it's important to get informed and ask a lot of questions! Hopefully you guys can help me to struggle along.
First off here's my new (old) bike:
It's a GT Timberline that I bought for $50 from this place where they take old bikes, tune them up, and then sell them.
1) Those nice shiny fenders I have on there are from an older junked mtb I had and the stays attached to the axle bolts of that bike. I took them off and put them on my new old mtb which uses quick release for both the front and rear wheel. I just wanted to make sure that it is okay to do this? If it is should I be putting some kind of washer or something else there? I really don't know if this is proper. Here are some pictures of what it looks like to help you guys get a better idea:
2) Is there one bolt/nut size/type that I should always be using for any "add-ons" so that I ensure that I need the fewest tools possible? And how do I decide what length/width bolts I should use for certain things? This one here looks like it may be a bit to long eh? Oh yeah and what about washers - where do I put them/what are they for/ do I need them on all bolts or only certain ones and do they go on both sides?:
Thanks a lot for the help everyone!
