Well I am doing some work experience at the moment in Bristol and I ride it to work every day and I have no problem stoping even downhill:) I used to ride a 52 14 gearing brake less. This is easy. Yeah I get the parts sh and fix them if neded. Soon I will get this to my goal of 4 kg
I love the bike, but no foot retention is just silly. There's no way you can ride a 52 14 down a hill at 35 mph and then just stop without foot straps or clips when an old lady walks out in front of you or a car backs out. That's near 100 gear inches. The gear ratio you have now is more reasonable for stopping without retention, but it's just an unnecessariy risk and plain stupid.
