Are FELT road bikes a good bike to buy at entry level??
Felt has made very nice bikes for years now. All bikes have a 3 piece crank. The mixing of parts is common in all manufacturers as they try to get bikes into certain price points. If you can save a little bit and wait a little longer I would wait and step up to the next level bike. Typically the only reason a person would buy sora parts on the bike is because they want the price point and aren’t sure if they are going to enjoy riding. If you know you like riding and want something that will last (components wise, the frame will be fine) step up to the next model and get FW35, the full 105 grouppo is going to be a world of difference in shift quality and will wear better than the tiagra or sora components. Talk to the shop your looking at the FW40 at and see if they have a year old FW35. If so you can normally get a slight deal on last years model.
