Selling my schwinn Mtb. Uncertain on the size, but it's on the small size for a lady. I've gotten more into road cycling and have no need for it. One shifter is broken, but I believe it might be a simple fix. You are more than welcome to have a look and make me an offer! Otherwise it's like brand-new. The tires have very small amount wear and I would say that it just has about 20-25 miles on it.
