Hello fellow mb'ers. I am still looking for a new front wheel for my trike. Have been looking around on the web and found some wheels. Not sure how they do it. I see rim width on some site, Do they measure it from the outer rim or from the inside the rim where the tire meets? I found 28mm width wheel from performance bikes. I am looking for 26x 1.50 to 1.75 with disc brakes. I want a strong rim like mtbs. The one i found is fort'e wheel. Is this a good wheel/rim? Thanks for any help!
