OK - I've spent an hour doing searches for 'front brakes' and 'emergency stops' and did find one thread with some info and a TDF video on emergency stops (the video was actually of sprinters crossing the line.)

Anyway, when I'm going fast (for me that would be 25+ mph) on a downhill or fast (12 - 15+ mph) on a flat and/or curved road, what would be the correct stopping manuever? Is it true that using the front brake is safer when used at speed than at slow speed? Should I always shift my weight to the back wheel when using the front brake?

Any threads/links and/or advice will be much appreciated and I will practice over the weekend. Thanks in advance while I go cook dinner and be back shortly to read any replies.

Thanks.
