thanks been riding for many many yrs and now older ride defensively BUT as you said their out to kill us so try as we like there is always something that can crop up ,idiot drivers , cows on a blind corner , kangaroos that aim , just that last brush with a idiot driver made me realise I needed to do something a bit better with the brakes than what iv been riding with the last couple of yrs ( also in mt country so steep dirt drive way /rds , where back brake saves the front end washing out ) , hence thinking of the thumb brake BUT had another look at the interagrated brakes to find there is a difference between intergrated and abs, both using the proporsioning valve BUT only the intergrated would work for my needs/ or any one else in my position ie. front lever operating both 60% front and 40% back , with the back also only operating via foot pedal , so have to chase up the older model pre abs bikes.. thanks those link are also great as the more info can get first will make it easier
