I got a Dolomite a few months ago. It's my first fat bike and the first bike I've had since I was a kid. Few things I'm wondering. Can I put a different cassette on it and make it easier to ride? If so what cassette, how many gears, front sprocket, derailer, shifter, etc...? Anyone know off hand what size the handle bar tube is so I can put bmx bars on it? I mainly use it to haul my kids around in the bike trailer but I'm going to do some riding up in the mountains on it. I think regearing it would help out. Other than that I love it. It's a fun bike and i get lots of stares and questions about it.
