I have a fixie pure bike for years that I brought back from my Stanford days and now in Maryland and recently joined a cycling group(casual riders -all of us are dads) and all the guys have a 16 to 20gear road and hybrid bikes. I'm struggling on the hills to keep up with the crew. Ive budgeted for 1k for a geared bike. What suggestions do the riders have(brands, gears)? Any other recs the riders that were once in my boat have would be highly appreciated.
