Obesity, Muscle Strength, and Gearing
I am looking to get a more Road oriented flatbar / finess / commuter bike. There are a lot of different choices out there and I am looking for opinions on a few things.
I currently ride a low end Comfort Specialized Expedition bike. I commute 7 miles from Spring to Fall on it generally at least 3 to 4 times a week. Some 15 mile weekend rides, etc. I was 370 pounds when I started on it. I am close to 310 now. My main complaint is not having enough gearing to go faster on flat and downhills. I think top speed is around 18-20mph according to my bike computer. What I DO like is having the OPTION to go up hills maybe max 20% grade in the lowest gear possible seated. (although I take most hills in a higher gear standing. I am obese but I think I have created some decent muscles sets for getting myself and 35+lb bike and backpack up hills.
Tire/Wheels - 26x1.95 wheels.
Casette -Shimano MFHG-37, 7-speed, 13-34t mega range
Chain Rings - 42S/34S/24S
Hub - Shimano FH-RM30S, cassette, 32h, QR
I am looking hard at the GT Tachyon 2.0. Obviously with 700cc x32 wheels I know it will feel really fast and probably be amazing on flat and downhills, but what about steep hills... Is the lowest gear to heavy?
It obviously has more road bike oriented gearing with a FSA Omega Triple 50/39/30t rings.
Do you think I might be walking this bike up hills?
