Umm, because I already bought a wheel on Amazon and my adapter didnt fit it. The adapter was too wide to fit between the spokes. The Howard adapter was designed specifically for the Cranbrook wheel, and after purchasing a different wheel and it not fitting, I'm not going to throw more money away on other wheels not knowing whether the adapter will fit or not. I truly do believe that the failure of my current wheel was due to abuse by the previous owner. And the other wheel I purchased came with a Shimano coaster brake, and that's what's going in the new Huffy wheel. I'm also not going to waste more money buying a different sprocket adapter. At some point I will end up spending more money on the bike than its actually worth, and that's when I start losing money. I'm really trying to avoid that. Realistically I'd say the most this bike is worth is $1800, and without lowballing, a fair offer would be about 1500. Not that I plan on selling it (seriously I don't, just making a point), but I've already spent about a grand on it. When I've spent $1300 or so, I'd say this bike becomes less of an investment and more of a money pit. It happened with my last bike, and I won't let it happen with this bike. I'm keeping the wheel that's on the bike, so if any spokes break on the new wheel, I will have spares. I'll be keeping a close eye on the new wheel, checking it over before and after each ride. But at this point, I don't have much of a choice because the hub on the cranbrook is the only hub I know of that's wide enough to take the Howard adapter.
