I'm after a Black rear sprocket , British Customs does one but it's £70 !!! and I want to try and keep the price for chain and both sprockets to about £120 . Has anyone ever painted the rear sprocket , what did you use and what were the results ?

problem with painting is its going to chip either way, powder coat or spray (water or cellulose). you will end up base colour around the teeth and once chipped corrosion will work its way under.
motocross Aluminium sprockets fair better as they are anodized which eats into the surface, especially hard anodized and can be purchased in multiple colours.
if you try paint,its got to be cleaned well and etched, maybe even anodized. Ive fitted chrome belt sprockets to Harleys and even the rubber/Kevlar compound peels after a time.
there are a few enamel paintersbut even the old bread bins chip after a while. a lot of coloured sprockets are on low mileage show bikes.
best I cann suggest is call into a spray shop like Bristol powder coating or Pharon these are more specialised industrial coaters rather than a bike sprayer
Thanks Wheelers , been doing a bit of research and it seems as you've stated , anodising is probably the way to go . Maybe it'll be a lot less hassle just getting the British Customs sprocket .Quote:

My rear sprocket is black..... shouldn't be, but I haven't cleaned the bike for the last 1500 miles.

Have decided not to be so bloody vain and stick with the standard steel replacement rear sprocket at a fraction of the cost . I was talking to Steve Lynham today and he reckons if an alloy sprocket is allowed to dry out even a little , a steel chain would chew the hell out of the teeth , and as I've had close to 30,000 miles out of the original parts , I'll stick with the same .
what you have to remember is Ally ones on mx bikes are changed and checked every race. which is why they look good and are replaced.
if you want to go colour on as steel, you could follow old British bikes...
work out where the chain will sit and allow approx. 5mm below. mask of above, covering the teeth and get the centre powder coated or enamelled.
When i bought my mtb, it had alloy chainrings, when they wore out, i just put steel deore rings on, last ten times longer :)

I didnt spray but have done BSA and Ariel's before. I got them sand blasted, not shot. then made sure dry.
if very fussy you could get them cadmium plated (gold film) as a corrosion preventative, then powder coat over the top. that way, if the paint does chip it should leave sprocket protected from rust with the plating.
the cadmium on steel isnt decorative just corrosion preventative.
Thanks for the info :cool:Quote:
