Entertaining thread! I’ve been a cyclist for years (only road, I own a MTB but don’t know much about mountain biking except that I enjoy it). I’m old school in some ways, I have not jumped on the Peloton train like most of it friends. I have a decent indoor trainer but it’s not a smart one (like its owner) and I absolutely hate riding on stationary trainers. I live in Chicago so it’s a necessary evil but I do not enjoy indoor suffering and try to ride outside unless it’s below 30F, raining or snowing.
Over the years I’ve owned decent aluminum road bikes from Cannondale and Specialize, and reasonably good carbon fiber and a well made steel bike (Reynolds 853). They all feel a bit different and geometry of each is a bit different (although size is approximately the same). Unless you are planning to race or join a fast group, I’ll be happy to give my ten cents and recommend getting a bike that fits you well. This includes the frame size, saddle, cockpit, etc. Get a professional fit if you can afford it. IMO, this will have a bigger impact on your enjoyment than anything else. My main bike has full SRAM Red from about ten years ago, and my steel bike has Shimano, a mix of DuraAce and Ultegra. They shift a bit differently and I prefer the SRAM but I could live with either. Same is true of Campy, once you get used to it, it works fine. I don’t have electronic shifting but have tested it several times and completely understand the allure. It’s pretty cool.
Fit and comfort are the most important areas you should focus on when you get started. Today’s aluminum bikes are better than I ever thought aluminum was capable of being. In my experience, tires are highly underrated and overlooked by too many cyclists. I love the fact that we are no longer putting 22mm tires on our road bikes and pumping them up to 110psi. So many cyclists are running fatter tires (25 or 28mm) and running lower pressure. In my experience this makes a bigger impact on comfort than frame material in general, especially if you are riding for fun and not racing or obsessed with every tenth of a second. All this talk is making me sad because I have a date with my stationary bike trainer tonight. Although I scoff at Peloton, I admit that I have a power meter on my stationary along with cadence HR monitor and a Garmin. Okay, I’m waiting for one of these Covid home cyclists to sell me a peloton cheap when when he/she gets tired of it next year.
