Hey there, I'm fairly new to cycling and I live in the Weston area. This place is an absolute paradise for road cyclists. Because of my "new" status, I have a very basic old Schwin MTB. I put road tires on it (much faster) and have upgraded the seat. I ride the thing flat out all of the time which is only about 18mph.
Basically, I'm just getting myself into "road" shape. So far, I've lost 13lbs. When I'm ready - I'll get a road bike and stop getting passed. Getting passed happens to me every day. However, I couldn't care less because I'm not racing - I'm losing weight and getting into shape.
I've modified the bike as much as it can be. I ride the seat pretty high. My legs have only a slight bend when the pedal is all of the way down. This routine will continue, most likely, for about another 3 months. When I feel comfortable - I'll switch to a road bike - which is a substantial investment.
If anybody out there wants to have a very fast and very safe ride - try Weston. Just say, "Hi" when you zip past me...
