I don’t think you can have too many shiny items – but for me there is cutoff in terms of maximum surface area of anodizing of any one item.
These Items are ok…..
brakes or bore caps
rotors
hubs
Bottom bracket
headset /headset spacers /Top Cap (but not all 3!)
Chainring
Seat Clamp
Jockey wheels
bolts (but not all of them)
valves
nobs and levers
Lock on grips
QR skewers
These are definitely not OK….
cranks
bars
seatpost
Pedals
rims
chain
cassette (Eagle looks nasty!)
frame (unless its just the frame and nothing else)
Grey Area….
stems
Historically I have said no to anodized stems but now that we are down to 35mm in length I’m not so sure? Id like input on this matter actually as I am currently on the fence over a black or red Hope stem…
Honestly the decisions I have to make, I don’t know how I cope sometimes!!
