I'm 135lbs fully geared up and my bike came with Codes. The first few times I used them, I accidentally locked up my wheels and almost fell. They definitely took some time to get used to.If you weigh less than 200, just about any brake is more than enough, unless you're dragging/boiling your brakes - which would not be the brakes shortcoming.
I love to see reviews of Codes or Ones by 155lb guys.... awesome.
