The bike I got earlier this spring, it came with 24"x3" Kenda Flame fat tires, and I want to keep the tires for my build. Obviously it's my first build, else I wouldn't be asking about the spokes. Anyway, I heard about how the extra torque has a tendency to snap them like twigs, and I figured the best way to get around that was mag rims. Lo and behold, 'twould appear there be none such a beast for yon tyres. Honest, I've looked. Widdled away seven hours on Google.
