I use to be a avid cyclist, Sworks Roubaix and Tarmac SL. 20 mile joy rides and centuries on the weekends. Had a bad tumble doing some MMA about 4 years ago, and here I sit at 325lbs.
Regardless, I have made the decision to get back on the bike, sold my jeep, and will make my life car free until I hit 200lbs.
Currently, I have a cheap rock hopper, which I commute 5 miles to work on, and just bought a Specialized Sirrus Carbon X1. Putting a 50 tooth front ring on, and should take delivery Friday.
The mtn bike is too slow, but will still use it twice a week to put the work in.
