These bikes greatly benefit from a slight gearing change. For that reason, I would recommend sourcing the drive components individually. You could pretty much match that kit price if you shop around, maybe even beat it. I would recommend the stock front 17T but drop the rear 1 tooth to a 33. D.I.D. makes one of the best standard chains and you can get one for about $40. If you want to save some money and take a chance, you might try one of these .....

I bought a couple and they look pretty nice. They are a well known brand (Takasago, they made your wheel rims) and made in Japan. I think they may be a decent chain for the money.
