I also just purchased a 747 this week. Another big bike in the Great White North. I'm 6'6" and 340lbs and will be mounting this on my trainer until I get myself down under the 300lb mark. In the meantime, I will continue to ride my Specialized Stumpjumper tank that I set up for road riding last year. Even once riding down at 300lbs, I am very interested in mounting some 28c Schwalbe Marathon Plus tires on this bike. I have read a couple threads that indicated 28c would be a tight fit but it looks like they should fit fine on my bike.
I was surprised that my bike came with Weinmann DA17 rims instead of the Weinmann DP18 rims the bike is spec'd with. Anyone else get these rims? From the Weinmann site, they appear to be a wider trekking rim designed for 23c/28c tires versus the DP18 which is a racing tire for 18c/23c tires. I am hoping that with the wider rim, a 28c tire might fit better. Thoughts?
