What is the main benefit to having double walled rims ?
I am thinking of changing the rims on the mountain bike that I am about to buy and want to get decent rims and a good pair of tires that are puncture resistant (for road cycling).
Any suggestions/recommendations on either would be much appreciated. I have the option of swapping parts for this bike at a discount when I buy it so want to get the best that I can.
PS..I live in Vancouver, B.C. so if you can recommend any good brands, I would really appreciate it.
