I'm strongly considering purchasing the Luna BBSHD kit for my bike and I've got a few questions before diving in.
1. Can I reuse the crank arms that are currently on my bike, or do I have to use the ones supplied with the kit?
2. From what I've read, there is general disdain for the heavy steel chainring that Bafang supplies with the kit. I noticed that Luna offers an aluminum one for an extra $40. I'm not sure if I should spend the extra money though. I would hate to purchase it only to find out the chain-line isn't correct. The bike is a Ghost Speedline 3 (https://www.rei.com/product/883669/ghost-speedline-3-bike-2016). This is not a fat bike or a mountain bike, but what I guess you'd call a commuter, so there is no wide swing-arm to account for. The dimensions are pretty average. What have the rest of you done?
