Get a new wheel before installing a rear rack?
Hey there, this is my first thread, although I've taken advice from this site for a while. So to get to it, I have a Schwinn mountain bike that is like 10 years old and am the 3rd person to use it and the only one to actually care for and tune it up in anyway. I use it almost exclusively for the road, since there aren't really any trails in or close to NYC. I have over 1500 miles on it now and last year I broke a spoke (although it may have been broken before I even got the bike) and a few days ago broke another one (both have been fixed, of course). I want to get a rear rack, mostly to carry either my backpack or from time to time shopping/groceries. A friend of mine said I should get a new wheel before installing a rear rack just to be safe, although 2 broken spokes after a year of hard riding, often times with a lot of weight on me, in bad weather and roads so bumpy and jagged they may as well be trails, doesn't seem that bad to me.
Any thought? I just didn't plan to spend an additional $60-100 or however much it'll cost to replace a 26 x 1.95 wheel, in addition to the $40 I will spend on the Topeak Super Tourist Rack (non disc brake/non spring one). Thanks ahead of time.
