Just received my 3rd pair of levers from the twowheels. good service as always, took just over 2 weeks to get here.
Like said above the brakes wont sudden jam on if they are incorrectly fitted, as heat builds up in the discs and pads the brakes will get firmer and firmer. your'll soon know if something is wrong when you're reving the nuts off the bike and its not going anywhere!
A simple check to make sure there is a small gap between the MC push rod and the lever, and also making sure the front wheel is free spinning is always a good idea after fitting any new levers.
No doubt the colours will fade if left out in all weathers and in direct sun.
You could easily got over this by giving them a coat of lacquer before fitting them.
But for 20 quid as apposed to 150 odd I cant complain.
